-# Exporting reference
-
-Welcome to the exporting engine reference guide. This guide contains comprehensive information about enabling,
-configuring, and monitoring Netdata's exporting engine, which allows you to send metrics to external time-series
-databases.
-
-For a quick introduction to the exporting engine's features, read our doc on [exporting metrics to time-series
-databases](https://github.com/netdata/netdata/blob/master/docs/export/external-databases.md), or jump in to [enabling a connector](https://github.com/netdata/netdata/blob/master/docs/export/enable-connector.md).
-
-The exporting engine has a modular structure and supports metric exporting via multiple exporting connector instances at
-the same time. You can have different update intervals and filters configured for every exporting connector instance. 
-
-When you enable the exporting engine and a connector, the Netdata Agent exports metrics _beginning from the time you
-restart its process_, not the entire [database of long-term metrics](https://github.com/netdata/netdata/blob/master/docs/store/change-metrics-storage.md).
-
-Since Netdata collects thousands of metrics per server per second, which would easily congest any database server when
-several Netdata servers are sending data to it, Netdata allows sending metrics at a lower frequency, by resampling them.
-
-So, although Netdata collects metrics every second, it can send to the external database servers averages or sums every
-X seconds (though, it can send them per second if you need it to).
-
-## Features
-
-### Integration
-
-The exporting engine uses a number of connectors to send Netdata metrics to external time-series databases. See our
-[list of supported databases](https://github.com/netdata/netdata/blob/master/docs/export/external-databases.md#supported-databases) for information on which
-connector to enable and configure for your database of choice.
-
--   [**AWS Kinesis Data Streams**](https://github.com/netdata/netdata/blob/master/exporting/aws_kinesis/README.md): Metrics are sent to the service in `JSON`
-    format.
--   [**Google Cloud Pub/Sub Service**](https://github.com/netdata/netdata/blob/master/exporting/pubsub/README.md): Metrics are sent to the service in `JSON`
-    format.
--   [**Graphite**](https://github.com/netdata/netdata/blob/master/exporting/graphite/README.md): A plaintext interface. Metrics are sent to the database server as
-    `prefix.hostname.chart.dimension`. `prefix` is configured below, `hostname` is the hostname of the machine (can
-    also be configured). Learn more in our guide to [export and visualize Netdata metrics in
-    Graphite](https://github.com/netdata/netdata/blob/master/exporting/graphite/README.md).
--   [**JSON** document databases](https://github.com/netdata/netdata/blob/master/exporting/json/README.md)
--   [**OpenTSDB**](https://github.com/netdata/netdata/blob/master/exporting/opentsdb/README.md): Use a plaintext or HTTP interfaces. Metrics are sent to
-    OpenTSDB as `prefix.chart.dimension` with tag `host=hostname`.
--   [**MongoDB**](https://github.com/netdata/netdata/blob/master/exporting/mongodb/README.md): Metrics are sent to the database in `JSON` format.
--   [**Prometheus**](https://github.com/netdata/netdata/blob/master/exporting/prometheus/README.md): Use an existing Prometheus installation to scrape metrics
-    from node using the Netdata API.
--   [**Prometheus remote write**](https://github.com/netdata/netdata/blob/master/exporting/prometheus/remote_write/README.md). A binary snappy-compressed protocol
-    buffer encoding over HTTP. Supports many [storage
-    providers](https://prometheus.io/docs/operating/integrations/#remote-endpoints-and-storage).
--   [**TimescaleDB**](https://github.com/netdata/netdata/blob/master/exporting/TIMESCALE.md): Use a community-built connector that takes JSON streams from a
-    Netdata client and writes them to a TimescaleDB table.
-
-### Chart filtering
-
-Netdata can filter metrics, to send only a subset of the collected metrics. You can use the
-configuration file
-
-```txt
-[prometheus:exporter]
-    send charts matching = system.*
-```
-
-or the URL parameter `filter` in the `allmetrics` API call.
-
-```txt
-http://localhost:19999/api/v1/allmetrics?format=shell&filter=system.*
-```
-
-### Operation modes
-
-Netdata supports three modes of operation for all exporting connectors:
-
--   `as-collected` sends to external databases the metrics as they are collected, in the units they are collected.
-    So, counters are sent as counters and gauges are sent as gauges, much like all data collectors do. For example,
-    to calculate CPU utilization in this format, you need to know how to convert kernel ticks to percentage.
-
--   `average` sends to external databases normalized metrics from the Netdata database. In this mode, all metrics
-    are sent as gauges, in the units Netdata uses. This abstracts data collection and simplifies visualization, but
-    you will not be able to copy and paste queries from other sources to convert units. For example, CPU utilization
-    percentage is calculated by Netdata, so Netdata will convert ticks to percentage and send the average percentage
-    to the external database.
-
--   `sum` or `volume`: the sum of the interpolated values shown on the Netdata graphs is sent to the external
-    database. So, if Netdata is configured to send data to the database every 10 seconds, the sum of the 10 values
-    shown on the Netdata charts will be used.
-
-Time-series databases suggest to collect the raw values (`as-collected`). If you plan to invest on building your
-monitoring around a time-series database and you already know (or you will invest in learning) how to convert units
-and normalize the metrics in Grafana or other visualization tools, we suggest to use `as-collected`.
-
-If, on the other hand, you just need long term archiving of Netdata metrics and you plan to mainly work with
-Netdata, we suggest to use `average`. It decouples visualization from data collection, so it will generally be a lot
-simpler. Furthermore, if you use `average`, the charts shown in the external service will match exactly what you
-see in Netdata, which is not necessarily true for the other modes of operation.
-
-### Independent operation
-
-This code is smart enough, not to slow down Netdata, independently of the speed of the external database server. 
-
-> ❗ You should keep in mind though that many exporting connector instances can consume a lot of CPU resources if they
-> run their batches at the same time. You can set different update intervals for every exporting connector instance,
-> but even in that case they can occasionally synchronize their batches for a moment.
-
-## Configuration
-
-Here are the configuration blocks for every supported connector. Your current `exporting.conf` file may look a little
-different. 
-
-You can configure each connector individually using the available [options](#options). The
-`[graphite:my_graphite_instance]` block contains examples of some of these additional options in action.
-
-```conf
-[exporting:global]
-    enabled = yes
-    send configured labels = no
-    send automatic labels = no
-    update every = 10
-
-[prometheus:exporter]

-    send configured labels = yes
-    send automatic labels = no
-    send charts matching = *
-    send hosts matching = localhost *
-    prefix = netdata
-
-[graphite:my_graphite_instance]
-    enabled = yes
-    destination = localhost:2003
-    data source = average
-    prefix = Netdata
-    hostname = my-name
-    update every = 10
-    buffer on failures = 10
-    timeout ms = 20000
-    send charts matching = *

-### Sections
-
--   `[exporting:global]` is a section where you can set your defaults for all exporting connectors
--   `[prometheus:exporter]` defines settings for Prometheus exporter API queries (e.g.:
-    `http://NODE:19999/api/v1/allmetrics?format=prometheus&help=yes&source=as-collected`).
--   `[<type>:<name>]` keeps settings for a particular exporting connector instance, where:
-  -   `type` selects the exporting connector type: graphite | opentsdb:telnet | opentsdb:http |
-      prometheus_remote_write | json | kinesis | pubsub | mongodb. For graphite, opentsdb,
-      json, and prometheus_remote_write connectors you can also use `:http` or `:https` modifiers
-      (e.g.: `opentsdb:https`).
-  -   `name` can be arbitrary instance name you chose.
-
-### Options
-
-Configure individual connectors and override any global settings with the following options.
-
--   `enabled = yes | no`, enables or disables an exporting connector instance
-
--   `destination = host1 host2 host3 ...`, accepts **a space separated list** of hostnames, IPs (IPv4 and IPv6) and
-     ports to connect to. Netdata will use the **first available** to send the metrics.
-
-     The format of each item in this list, is: `[PROTOCOL:]IP[:PORT]`.
-
-     `PROTOCOL` can be `udp` or `tcp`. `tcp` is the default and only supported by the current exporting engine.
-
-     `IP` can be `XX.XX.XX.XX` (IPv4), or `[XX:XX...XX:XX]` (IPv6). For IPv6 you can to enclose the IP in `[]` to
-     separate it from the port.
-
-     `PORT` can be a number of a service name. If omitted, the default port for the exporting connector will be used
-     (graphite = 2003, opentsdb = 4242).
-
-     Example IPv4:
-
-```conf
-   destination = 10.11.14.2:4242 10.11.14.3:4242 10.11.14.4:4242
-```
-
-   Example IPv6 and IPv4 together:
-
-```conf
-   destination = [ffff:...:0001]:2003 10.11.12.1:2003
-```
-
-   When multiple servers are defined, Netdata will try the next one when the previous one fails.
-
-   Netdata also ships `nc-exporting.sh`, a script that can be used as a fallback exporting connector to save the
-   metrics to disk and push them to the time-series database when it becomes available again. It can also be used to
-   monitor / trace / debug the metrics Netdata generates.
-
-   For the Kinesis exporting connector `destination` should be set to an AWS region (for example, `us-east-1`).
-
-   For the MongoDB exporting connector `destination` should be set to a
-   [MongoDB URI](https://docs.mongodb.com/manual/reference/connection-string/).
-
-   For the Pub/Sub exporting connector `destination` can be set to a specific service endpoint.
-
--   `data source = as collected`, or `data source = average`, or `data source = sum`, selects the kind of data that will
-     be sent to the external database.
-
--   `hostname = my-name`, is the hostname to be used for sending data to the external database server. By default this
-    is `[global].hostname`.
-
--   `prefix = Netdata`, is the prefix to add to all metrics.
-
--   `update every = 10`, is the number of seconds between sending data to the external database. Netdata will add some
-    randomness to this number, to prevent stressing the external server when many Netdata servers send data to the same
-    database. This randomness does not affect the quality of the data, only the time they are sent.
-
--   `buffer on failures = 10`, is the number of iterations (each iteration is `update every` seconds) to buffer data,
-    when the external database server is not available. If the server fails to receive the data after that many
-    failures, data loss on the connector instance is expected (Netdata will also log it).
-
--   `timeout ms = 20000`, is the timeout in milliseconds to wait for the external database server to process the data.
-    By default this is `2 * update_every * 1000`.
-
--   `send hosts matching = localhost *` includes one or more space separated patterns, using `*` as wildcard (any number
-    of times within each pattern). The patterns are checked against the hostname (the localhost is always checked as
-    `localhost`), allowing us to filter which hosts will be sent to the external database when this Netdata is a central
-    Netdata aggregating multiple hosts. A pattern starting with `!` gives a negative match. So to match all hosts named
-    `*db*` except hosts containing `*child*`, use `!*child* *db*` (so, the order is important: the first
-    pattern matching the hostname will be used - positive or negative).
-
--   `send charts matching = *` includes one or more space separated patterns, using `*` as wildcard (any number of times
-    within each pattern). The patterns are checked against both chart id and chart name. A pattern starting with `!`
-    gives a negative match. So to match all charts named `apps.*` except charts ending in `*reads`, use `!*reads
-    apps.*` (so, the order is important: the first pattern matching the chart id or the chart name will be used -
-    positive or negative). There is also a URL parameter `filter` that can be used while querying `allmetrics`. The URL
-    parameter has a higher priority than the configuration option.
-
--   `send names instead of ids = yes | no` controls the metric names Netdata should send to the external database.
-    Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system
-    and names are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several
-    cases they are different: disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc.
-
--   `send configured labels = yes | no` controls if host labels defined in the `[host labels]` section in `netdata.conf`
-    should be sent to the external database
-
--   `send automatic labels = yes | no` controls if automatically created labels, like `_os_name` or `_architecture`
-    should be sent to the external database
-
-## HTTPS
-
-Netdata can send metrics to external databases using the TLS/SSL protocol. Unfortunately, some of
-them does not support encrypted connections, so you will have to configure a reverse proxy to enable
-HTTPS communication between Netdata and an external database. You can set up a reverse proxy with
-[Nginx](https://github.com/netdata/netdata/blob/master/docs/Running-behind-nginx.md).
-
-## Exporting engine monitoring
-
-Netdata creates five charts in the dashboard, under the **Netdata Monitoring** section, to help you monitor the health
-and performance of the exporting engine itself:
-
-1.  **Buffered metrics**, the number of metrics Netdata added to the buffer for dispatching them to the
-    external database server.
-
-2.  **Exporting data size**, the amount of data (in KB) Netdata added the buffer.
-
-3.  **Exporting operations**, the number of operations performed by Netdata.
-
-4.  **Exporting thread CPU usage**, the CPU resources consumed by the Netdata thread, that is responsible for sending
-    the metrics to the external database server.

-
-## Exporting engine alerts
-
-Netdata adds 3 alerts:
-
-1.  `exporting_last_buffering`, number of seconds since the last successful buffering of exported data
-2.  `exporting_metrics_sent`, percentage of metrics sent to the external database server
-3.  `exporting_metrics_lost`, number of metrics lost due to repeating failures to contact the external database server

-## Setup
-
-### Prerequisites
-
-#### 
-
-- You have already installed Netdata and Graphite.
-
-
-
-### Configuration
-
-#### File
-
-The configuration file name for this integration is `exporting.conf`.
-
-
-You can edit the configuration file using the `edit-config` script from the
-Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
-
-```bash
-cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
-sudo ./edit-config exporting.conf
-```
-#### Options
-
-The following options can be defined for this exporter.
-
-<details><summary>Config options</summary>
-
-| Name | Description | Default | Required |
-|:----|:-----------|:-------|:--------:|
-| enabled | Enables or disables an exporting connector instance (yes/no). | no | yes |
-| destination | Accepts a space separated list of hostnames, IPs (IPv4 and IPv6) and ports to connect to. Netdata will use the first available to send the metrics. | no | yes |
-| username | Username for HTTP authentication | my_username | no |
-| password | Password for HTTP authentication | my_password | no |
-| data source | Selects the kind of data that will be sent to the external database. (as collected/average/sum) |  | no |
-| hostname | The hostname to be used for sending data to the external database server. | [global].hostname | no |
-| prefix | The prefix to add to all metrics. | netdata | no |
-| update every | Frequency of sending sending data to the external database, in seconds. | 10 | no |
-| buffer on failures | The number of iterations (`update every` seconds) to buffer data, when the external database server is not available. | 10 | no |
-| timeout ms | The timeout in milliseconds to wait for the external database server to process the data. | 20000 | no |
-| send hosts matching | Hosts filter. Determines which hosts will be sent to the external database. The syntax is [simple patterns](https://github.com/netdata/netdata/tree/master/libnetdata/simple_pattern#simple-patterns). | localhost * | no |
-| send charts matching | One or more space separated patterns (use * as wildcard) checked against both chart id and chart name. | * | no |
-| send names instead of ids | Controls the metric names Netdata should send to the external database (yes/no). |  | no |
-| send configured labels | Controls if host labels defined in the `[host labels]` section in `netdata.conf` should be sent to the external database (yes/no). |  | no |
-| send automatic labels | Controls if automatically created labels, like `_os_name` or `_architecture` should be sent to the external database (yes/no). |  | no |
-
-##### destination
-
-The format of each item in this list, is: [PROTOCOL:]IP[:PORT].
-- PROTOCOL can be udp or tcp. tcp is the default and only supported by the current exporting engine.
-- IP can be XX.XX.XX.XX (IPv4), or [XX:XX...XX:XX] (IPv6). For IPv6 you can to enclose the IP in [] to separate it from the port.
-- PORT can be a number of a service name. If omitted, the default port for the exporting connector will be used.
-
-Example IPv4:
-  ```yaml
-  destination = 10.11.14.2:2003 10.11.14.3:4242 10.11.14.4:2003
-  ```
-Example IPv6 and IPv4 together:
-```yaml
-destination = [ffff:...:0001]:2003 10.11.12.1:2003
-```
-When multiple servers are defined, Netdata will try the next one when the previous one fails.
-
-
-##### update every
-
-Netdata will add some randomness to this number, to prevent stressing the external server when many Netdata servers
-send data to the same database. This randomness does not affect the quality of the data, only the time they are sent.
-
-
-##### buffer on failures
-
-If the server fails to receive the data after that many failures, data loss on the connector instance is expected (Netdata will also log it).
-
-
-##### send hosts matching
-
-Includes one or more space separated patterns, using * as wildcard (any number of times within each pattern).
-The patterns are checked against the hostname (the localhost is always checked as localhost), allowing us to
-filter which hosts will be sent to the external database when this Netdata is a central Netdata aggregating multiple hosts.
-
-A pattern starting with `!` gives a negative match. So to match all hosts named `*db*` except hosts containing `*child*`,
-use `!*child* *db*` (so, the order is important: the first pattern matching the hostname will be used - positive or negative).
-
-
-##### send charts matching
-
-A pattern starting with ! gives a negative match. So to match all charts named apps.* except charts ending in *reads,
-use !*reads apps.* (so, the order is important: the first pattern matching the chart id or the chart name will be used,
-positive or negative). There is also a URL parameter filter that can be used while querying allmetrics. The URL parameter
-has a higher priority than the configuration option.
-
-
-##### send names instead of ids
-
-Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system and names
-are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several cases they are
-different : disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc.
-
-
-</details>
-
-#### Examples
-
-##### Example configuration
-
-Basic configuration
-
-```yaml
-[graphite:netdata]
-    enabled = yes
-    destination = localhost:2003
-
-```
-##### Configuration with HTTPS and HTTP authentication
-
-Add `:https` modifier to the connector type if you need to use the TLS/SSL protocol. For example: `remote_write:https:my_instance`.
-
-```yaml
-[graphite:netdata]
-    enabled = yes
-    destination = localhost:2003
-    username = my_username
-    password = my_password
-
-```
-##### Detailed Configuration for a remote, secure host
-
-Add `:https` modifier to the connector type if you need to use the TLS/SSL protocol. For example: `remote_write:https:my_instance`.
-
-```yaml
-[graphite:https:netdata]
-    enabled = yes
-    username = my_username
-    password = my_password
-    destination = 10.10.1.114:2003
-    # data source = average
-    # prefix = netdata
-    # hostname = my_hostname
-    # update every = 10
-    # buffer on failures = 10
-    # timeout ms = 20000
-    # send names instead of ids = yes
-    # send charts matching = *
-    # send hosts matching = localhost *
-

-# MongoDB
-
-
-<img src="https://netdata.cloud/img/mongodb.svg" width="150"/>
-
-
-Use the MongoDB connector for the exporting engine to archive your agent's metrics to a MongoDB database
-for long-term storage, further analysis, or correlation with data from other sources.
-
-
-
-<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
-
-## Setup
-
-### Prerequisites
-
-#### 
-
-- To use MongoDB as an external storage for long-term archiving, you should first [install](http://mongoc.org/libmongoc/current/installing.html) libmongoc 1.7.0 or higher.
-- Next, re-install Netdata from the source, which detects that the required library is now available.
-
-
-
-### Configuration
-
-#### File
-
-The configuration file name for this integration is `exporting.conf`.
-
-
-You can edit the configuration file using the `edit-config` script from the
-Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
-
-```bash
-cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
-sudo ./edit-config exporting.conf
-```
-#### Options
-
-The following options can be defined for this exporter.
-
-
-<details><summary>Config options</summary>
-
-| Name | Description | Default | Required |
-|:----|:-----------|:-------|:--------:|
-| enabled | Enables or disables an exporting connector instance (yes/no). | no | yes |
-| destination | Accepts a space separated list of hostnames, IPs (IPv4 and IPv6) and ports to connect to. Netdata will use the first available to send the metrics. | localhost | yes |
-| username | Username for HTTP authentication | my_username | no |
-| password | Password for HTTP authentication | my_password | no |
-| data source | Selects the kind of data that will be sent to the external database. (as collected/average/sum) |  | no |
-| hostname | The hostname to be used for sending data to the external database server. | [global].hostname | no |
-| prefix | The prefix to add to all metrics. | Netdata | no |
-| update every | Frequency of sending sending data to the external database, in seconds. | 10 | no |
-| buffer on failures | The number of iterations (`update every` seconds) to buffer data, when the external database server is not available. | 10 | no |
-| timeout ms | The timeout in milliseconds to wait for the external database server to process the data. | 2 * update_every * 1000 | no |
-| send hosts matching | Hosts filter. Determines which hosts will be sent to the external database. The syntax is [simple patterns](https://github.com/netdata/netdata/tree/master/libnetdata/simple_pattern#simple-patterns). | localhost * | no |
-| send charts matching | One or more space separated patterns (use * as wildcard) checked against both chart id and chart name. | * | no |
-| send names instead of ids | Controls the metric names Netdata should send to the external database (yes/no). |  | no |
-| send configured labels | Controls if host labels defined in the `[host labels]` section in `netdata.conf` should be sent to the external database (yes/no). |  | no |
-| send automatic labels | Controls if automatically created labels, like `_os_name` or `_architecture` should be sent to the external database (yes/no). |  | no |
-
-##### destination
-
-The format of each item in this list, is: [PROTOCOL:]IP[:PORT].
-- PROTOCOL can be udp or tcp. tcp is the default and only supported by the current exporting engine.
-- IP can be XX.XX.XX.XX (IPv4), or [XX:XX...XX:XX] (IPv6). For IPv6 you can to enclose the IP in [] to separate it from the port.
-- PORT can be a number of a service name. If omitted, the default port for the exporting connector will be used.
-
-Example IPv4:
-  ```yaml
-  destination = 10.11.14.2:27017 10.11.14.3:4242 10.11.14.4:27017
-  ```
-Example IPv6 and IPv4 together:
-```yaml
-destination = [ffff:...:0001]:2003 10.11.12.1:2003
-```
-When multiple servers are defined, Netdata will try the next one when the previous one fails.
-
-
-##### update every
-
-Netdata will add some randomness to this number, to prevent stressing the external server when many Netdata servers
-send data to the same database. This randomness does not affect the quality of the data, only the time they are sent.
-
-
-##### buffer on failures
-
-If the server fails to receive the data after that many failures, data loss on the connector instance is expected (Netdata will also log it).
-
-
-##### send hosts matching
-
-Includes one or more space separated patterns, using * as wildcard (any number of times within each pattern).
-The patterns are checked against the hostname (the localhost is always checked as localhost), allowing us to
-filter which hosts will be sent to the external database when this Netdata is a central Netdata aggregating multiple hosts.
-
-A pattern starting with `!` gives a negative match. So to match all hosts named `*db*` except hosts containing `*child*`,
-use `!*child* *db*` (so, the order is important: the first pattern matching the hostname will be used - positive or negative).
-
-
-##### send charts matching
-
-A pattern starting with ! gives a negative match. So to match all charts named apps.* except charts ending in *reads,
-use !*reads apps.* (so, the order is important: the first pattern matching the chart id or the chart name will be used,
-positive or negative). There is also a URL parameter filter that can be used while querying allmetrics. The URL parameter
-has a higher priority than the configuration option.
-
-
-##### send names instead of ids
-
-Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system and names
-are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several cases they are
-different : disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc.
-
-
-</details>
-
-#### Examples
-
-##### Basic configuration
-
-The default socket timeout depends on the exporting connector update interval.
-The timeout is 500 ms shorter than the interval (but not less than 1000 ms). You can alter the timeout using the sockettimeoutms MongoDB URI option.
-
-
-```yaml
-[mongodb:my_instance]
-    enabled = yes
-    destination = mongodb://<hostname>
-    database = your_database_name
-    collection = your_collection_name
-
-```

-# Using Netdata with Prometheus
-
-Netdata supports exporting metrics to Prometheus in two ways:
-
- - You can [configure Prometheus to scrape Netdata metrics](#configure-prometheus-to-scrape-netdata-metrics).
-
- - You can [configure Netdata to push metrics to Prometheus](https://github.com/netdata/netdata/blob/master/exporting/prometheus/remote_write/README.md)
-   , using the Prometheus remote write API.
-
-## Netdata support for Prometheus
-
-Regardless of the methodology, you first need to understand how Netdata structures the metrics it exports to Prometheus
-and the capabilities it provides. The examples provided in this document assume that you will be using Netdata as 
-a metrics endpoint, but the concepts apply as well to the remote write API method.
-
-### Understanding Netdata metrics
-
-#### Charts
-
-Each chart in Netdata has several properties (common to all its metrics):
-
-- `chart_id` - uniquely identifies a chart.
-
-- `chart_name` - a more human friendly name for `chart_id`, also unique.
-
-- `context` - this is the template of the chart. All disk I/O charts have the same context, all mysql requests charts
-  have the same context, etc. This is used for alert templates to match all the charts they should be attached to.
-
-- `family` groups a set of charts together. It is used as the submenu of the dashboard.
-
-- `units` is the units for all the metrics attached to the chart.
-
-#### Dimensions
-
-Then each Netdata chart contains metrics called `dimensions`. All the dimensions of a chart have the same units of
-measurement, and are contextually in the same category (ie. the metrics for disk bandwidth are `read` and `write` and
-they are both in the same chart).
-
-### Netdata data source
-
-Netdata can send metrics to Prometheus from 3 data sources:
-
-- `as collected` or `raw` - this data source sends the metrics to Prometheus as they are collected. No conversion is
-  done by Netdata. The latest value for each metric is just given to Prometheus. This is the most preferred method by
-  Prometheus, but it is also the harder to work with. To work with this data source, you will need to understand how
-  to get meaningful values out of them.
-
-  The format of the metrics is: `CONTEXT{chart="CHART",family="FAMILY",dimension="DIMENSION"}`.
-
-  If the metric is a counter (`incremental` in Netdata lingo), `_total` is appended the context.
-
-  Unlike Prometheus, Netdata allows each dimension of a chart to have a different algorithm and conversion constants
-  (`multiplier` and `divisor`). In this case, that the dimensions of a charts are heterogeneous, Netdata will use this
-  format: `CONTEXT_DIMENSION{chart="CHART",family="FAMILY"}`
-
-- `average` - this data source uses the Netdata database to send the metrics to Prometheus as they are presented on
-  the Netdata dashboard. So, all the metrics are sent as gauges, at the units they are presented in the Netdata
-  dashboard charts. This is the easiest to work with.
-
-  The format of the metrics is: `CONTEXT_UNITS_average{chart="CHART",family="FAMILY",dimension="DIMENSION"}`.
-
-  When this source is used, Netdata keeps track of the last access time for each Prometheus server fetching the
-  metrics. This last access time is used at the subsequent queries of the same Prometheus server to identify the
-  time-frame the `average` will be calculated.
-
-  So, no matter how frequently Prometheus scrapes Netdata, it will get all the database data.
-  To identify each Prometheus server, Netdata uses by default the IP of the client fetching the metrics.
-
-  If there are multiple Prometheus servers fetching data from the same Netdata, using the same IP, each Prometheus
-  server can append `server=NAME` to the URL. Netdata will use this `NAME` to uniquely identify the Prometheus server.
-
-- `sum` or `volume`, is like `average` but instead of averaging the values, it sums them.
-
-  The format of the metrics is: `CONTEXT_UNITS_sum{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. All the
-  other operations are the same with `average`.
-
-  To change the data source to `sum` or `as-collected` you need to provide the `source` parameter in the request URL.
-  e.g.: `http://your.netdata.ip:19999/api/v1/allmetrics?format=prometheus&help=yes&source=as-collected`
-
-  Keep in mind that early versions of Netdata were sending the metrics as: `CHART_DIMENSION{}`.
-
-### Querying Metrics
-
-Fetch with your web browser this URL:
-
-`http://your.netdata.ip:19999/api/v1/allmetrics?format=prometheus&help=yes`
-
-_(replace `your.netdata.ip` with the ip or hostname of your Netdata server)_
-
-Netdata will respond with all the metrics it sends to Prometheus.
-
-If you search that page for `"system.cpu"` you will find all the metrics Netdata is exporting to Prometheus for this
-chart. `system.cpu` is the chart name on the Netdata dashboard (on the Netdata dashboard all charts have a text heading
-such as : `Total CPU utilization (system.cpu)`. What we are interested here in the chart name: `system.cpu`).
-
-Searching for `"system.cpu"` reveals:
-
-```sh

-### Streaming data from upstream hosts
-
-The `format=prometheus` parameter only exports the host's Netdata metrics. If you are using the parent-child
-functionality of Netdata this ignores any upstream hosts - so you should consider using the below in your
-**prometheus.yml**:
-
-```yaml
-    metrics_path: '/api/v1/allmetrics'
-    params:
-      format: [ prometheus_all_hosts ]
-    honor_labels: true
-```
-
-This will report all upstream host data, and `honor_labels` will make Prometheus take note of the instance names
-provided.
-
-### Timestamps
-
-To pass the metrics through Prometheus pushgateway, Netdata supports the option `&timestamps=no` to send the metrics
-without timestamps.
-
-## Netdata host variables
-
-Netdata collects various system configuration metrics, like the max number of TCP sockets supported, the max number of
-files allowed system-wide, various IPC sizes, etc. These metrics are not exposed to Prometheus by default.
-
-To expose them, append `variables=yes` to the Netdata URL.
-
-### TYPE and HELP
-
-To save bandwidth, and because Prometheus does not use them anyway, `# TYPE` and `# HELP` lines are suppressed. If
-wanted they can be re-enabled via `types=yes` and `help=yes`, e.g.
-`/api/v1/allmetrics?format=prometheus&types=yes&help=yes`
-
-Note that if enabled, the `# TYPE` and `# HELP` lines are repeated for every occurrence of a metric, which goes against
-the Prometheus
-documentation's [specification for these lines](https://github.com/prometheus/docs/blob/master/content/docs/instrumenting/exposition_formats.md#comments-help-text-and-type-information).
-
-### Names and IDs
-
-Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system and
-names are human friendly labels (also unique).
-
-Most charts and metrics have the same ID and name, but in several cases they are different: disks with device-mapper,
-interrupts, QoS classes, statsd synthetic charts, etc.
-
-The default is controlled in `exporting.conf`:
-
-```conf
-[prometheus:exporter]
-	send names instead of ids = yes | no
-```
-
-You can overwrite it from Prometheus, by appending to the URL:
-
-- `&names=no` to get IDs (the old behaviour)
-- `&names=yes` to get names
-
-### Filtering metrics sent to Prometheus
-
-Netdata can filter the metrics it sends to Prometheus with this setting:
-
-```conf
-[prometheus:exporter]
-	send charts matching = *
-```
-
-This settings accepts a space separated list
-of [simple patterns](https://github.com/netdata/netdata/blob/master/libnetdata/simple_pattern/README.md) to match the
-**charts** to be sent to Prometheus. Each pattern can use `*` as wildcard, any number of times (e.g `*a*b*c*` is valid).
-Patterns starting with `!` give a negative match (e.g `!*.bad users.* groups.*` will send all the users and groups
-except `bad` user and `bad` group). The order is important: the first match (positive or negative) left to right, is
-used.
-
-### Changing the prefix of Netdata metrics
-
-Netdata sends all metrics prefixed with `netdata_`. You can change this in `netdata.conf`, like this:
-
-```conf
-[prometheus:exporter]
-	prefix = netdata
-```
-
-It can also be changed from the URL, by appending `&prefix=netdata`.
-
-### Metric Units
-
-The default source `average` adds the unit of measurement to the name of each metric (e.g. `_KiB_persec`). To hide the
-units and get the same metric names as with the other sources, append to the URL `&hideunits=yes`.
-
-The units were standardized in v1.12, with the effect of changing the metric names. To get the metric names as they were
-before v1.12, append to the URL `&oldunits=yes`
-
-### Accuracy of `average` and `sum` data sources
-
-When the data source is set to `average` or `sum`, Netdata remembers the last access of each client accessing Prometheus
-metrics and uses this last access time to respond with the `average` or `sum` of all the entries in the database since
-that. This means that Prometheus servers are not losing data when they access Netdata with data source = `average` or
-`sum`.
-
-To uniquely identify each Prometheus server, Netdata uses the IP of the client accessing the metrics. If however the IP
-is not good enough for identifying a single Prometheus server (e.g. when Prometheus servers are accessing Netdata
-through a web proxy, or when multiple Prometheus servers are NATed to a single IP), each Prometheus may append
-`&server=NAME` to the URL. This `NAME` is used by Netdata to uniquely identify each Prometheus server and keep track of
-its last access time.
-
-## Configure Prometheus to scrape Netdata metrics
-
-The following `prometheus.yml` file will scrape all netdata metrics "as collected". 
-
-Make sure to replace `your.netdata.ip` with the IP or hostname of the host running Netdata.
-
-```yaml
-# my global config
-global:
-  scrape_interval: 5s # Set the scrape interval to every 5 seconds. Default is every 1 minute.
-  evaluation_interval: 5s # Evaluate rules every 5 seconds. The default is every 1 minute.
-  # scrape_timeout is set to the global default (10s).
-
-  # Attach these labels to any time series or alerts when communicating with
-  # external systems (federation, remote storage, Alertmanager).
-  external_labels:
-    monitor: 'codelab-monitor'
-
-# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
-rule_files:
-# - "first.rules"
-# - "second.rules"
-
-# A scrape configuration containing exactly one endpoint to scrape:
-# Here it's Prometheus itself.
-scrape_configs:
-  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
-  - job_name: 'prometheus'
-
-    # metrics_path defaults to '/metrics'
-    # scheme defaults to 'http'.
-
-    static_configs:
-      - targets: [ '0.0.0.0:9090' ]
-
-  - job_name: 'netdata-scrape'
-
-    metrics_path: '/api/v1/allmetrics'
-    params:
-      # format: prometheus | prometheus_all_hosts
-      # You can use `prometheus_all_hosts` if you want Prometheus to set the `instance` to your hostname instead of IP 
-      format: [ prometheus ]
-      #
-      # sources: as-collected | raw | average | sum | volume
-      # default is: average
-      #source: [as-collected]
-      #
-      # server name for this prometheus - the default is the client IP
-      # for Netdata to uniquely identify it
-      #server: ['prometheus1']
-    honor_labels: true
-
-    static_configs:
-      - targets: [ '{your.netdata.ip}:19999' ]
-```
-
-### Prometheus alerts for Netdata metrics
-
-The following is an example of a `nodes.yml` file that will allow Prometheus to generate alerts from some Netdata sources. 
-Save it at `/opt/prometheus/nodes.yml`, and add a _- "nodes.yml"_ entry under the _rule_files:_ section in the example prometheus.yml file above.
-
-```yaml
-groups:
-  - name: nodes
-

-#### File
-
-The configuration file name for this integration is `exporting.conf`.
-
-
-You can edit the configuration file using the `edit-config` script from the
-Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
-
-```bash
-cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
-sudo ./edit-config exporting.conf
-```
-#### Options
-
-The following options can be defined for this exporter.
-
-<details><summary>Config options</summary>
-
-| Name | Description | Default | Required |
-|:----|:-----------|:-------|:--------:|
-| enabled | Enables or disables an exporting connector instance (yes/no). | no | yes |
-| destination | Accepts a space separated list of hostnames, IPs (IPv4 and IPv6) and ports to connect to. Netdata will use the first available to send the metrics. | no | yes |
-| username | Username for HTTP authentication | my_username | no |
-| password | Password for HTTP authentication | my_password | no |
-| data source | Selects the kind of data that will be sent to the external database. (as collected/average/sum) |  | no |
-| hostname | The hostname to be used for sending data to the external database server. | [global].hostname | no |
-| prefix | The prefix to add to all metrics. | netdata | no |
-| update every | Frequency of sending sending data to the external database, in seconds. | 10 | no |
-| buffer on failures | The number of iterations (`update every` seconds) to buffer data, when the external database server is not available. | 10 | no |
-| timeout ms | The timeout in milliseconds to wait for the external database server to process the data. | 20000 | no |
-| send hosts matching | Hosts filter. Determines which hosts will be sent to the external database. The syntax is [simple patterns](https://github.com/netdata/netdata/tree/master/libnetdata/simple_pattern#simple-patterns). | localhost * | no |
-| send charts matching | One or more space separated patterns (use * as wildcard) checked against both chart id and chart name. | * | no |
-| send names instead of ids | Controls the metric names Netdata should send to the external database (yes/no). |  | no |
-| send configured labels | Controls if host labels defined in the `[host labels]` section in `netdata.conf` should be sent to the external database (yes/no). |  | no |
-| send automatic labels | Controls if automatically created labels, like `_os_name` or `_architecture` should be sent to the external database (yes/no). |  | no |
-
-##### destination
-
-The format of each item in this list, is: [PROTOCOL:]IP[:PORT].
-- PROTOCOL can be udp or tcp. tcp is the default and only supported by the current exporting engine.
-- IP can be XX.XX.XX.XX (IPv4), or [XX:XX...XX:XX] (IPv6). For IPv6 you can to enclose the IP in [] to separate it from the port.
-- PORT can be a number of a service name. If omitted, the default port for the exporting connector will be used.
-
-Example IPv4:
-  ```yaml
-  destination = 10.11.14.2:2003 10.11.14.3:4242 10.11.14.4:2003
-  ```
-Example IPv6 and IPv4 together:
-```yaml
-destination = [ffff:...:0001]:2003 10.11.12.1:2003
-```
-When multiple servers are defined, Netdata will try the next one when the previous one fails.
-
-
-##### update every
-
-Netdata will add some randomness to this number, to prevent stressing the external server when many Netdata servers
-send data to the same database. This randomness does not affect the quality of the data, only the time they are sent.
-
-
-##### buffer on failures
-
-If the server fails to receive the data after that many failures, data loss on the connector instance is expected (Netdata will also log it).
-
-
-##### send hosts matching
-
-Includes one or more space separated patterns, using * as wildcard (any number of times within each pattern).
-The patterns are checked against the hostname (the localhost is always checked as localhost), allowing us to
-filter which hosts will be sent to the external database when this Netdata is a central Netdata aggregating multiple hosts.
-
-A pattern starting with `!` gives a negative match. So to match all hosts named `*db*` except hosts containing `*child*`,
-use `!*child* *db*` (so, the order is important: the first pattern matching the hostname will be used - positive or negative).
-
-
-##### send charts matching
-
-A pattern starting with ! gives a negative match. So to match all charts named apps.* except charts ending in *reads,
-use !*reads apps.* (so, the order is important: the first pattern matching the chart id or the chart name will be used,
-positive or negative). There is also a URL parameter filter that can be used while querying allmetrics. The URL parameter
-has a higher priority than the configuration option.
-
-
-##### send names instead of ids
-
-Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system and names
-are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several cases they are
-different : disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc.
-
-

-
-#### Examples
-
-##### Example configuration
-
-Basic example configuration for Prometheus remote write.
-
-```yaml
-[prometheus_remote_write:my_instance]
-    enabled = yes
-    destination = 10.11.14.2:2003
-    remote write URL path = /receive
-
-```
-##### Example configuration with HTTPS and HTTP authentication
-
-Add `:https` modifier to the connector type if you need to use the TLS/SSL protocol. For example: `remote_write:https:my_instance`.
-
-```yaml
-[prometheus_remote_write:https:my_instance]
-    enabled = yes
-    destination = 10.11.14.2:2003
-    remote write URL path = /receive
-    username = my_username
-    password = my_password

-| enabled | Enables or disables an exporting connector instance (yes/no). | no | yes |
-| destination | Accepts a space separated list of hostnames, IPs (IPv4 and IPv6) and ports to connect to. Netdata will use the first available to send the metrics. | no | yes |
-| username | Username for HTTP authentication | my_username | no |
-| password | Password for HTTP authentication | my_password | no |
-| data source | Selects the kind of data that will be sent to the external database. (as collected/average/sum) |  | no |
-| hostname | The hostname to be used for sending data to the external database server. | [global].hostname | no |
-| prefix | The prefix to add to all metrics. | netdata | no |
-| update every | Frequency of sending sending data to the external database, in seconds. | 10 | no |
-| buffer on failures | The number of iterations (`update every` seconds) to buffer data, when the external database server is not available. | 10 | no |
-| timeout ms | The timeout in milliseconds to wait for the external database server to process the data. | 20000 | no |
-| send hosts matching | Hosts filter. Determines which hosts will be sent to the external database. The syntax is [simple patterns](https://github.com/netdata/netdata/tree/master/libnetdata/simple_pattern#simple-patterns). | localhost * | no |
-| send charts matching | One or more space separated patterns (use * as wildcard) checked against both chart id and chart name. | * | no |
-| send names instead of ids | Controls the metric names Netdata should send to the external database (yes/no). |  | no |

-##### destination
-
-The format of each item in this list, is: [PROTOCOL:]IP[:PORT].
-- PROTOCOL can be udp or tcp. tcp is the default and only supported by the current exporting engine.
-- IP can be XX.XX.XX.XX (IPv4), or [XX:XX...XX:XX] (IPv6). For IPv6 you can to enclose the IP in [] to separate it from the port.
-- PORT can be a number of a service name. If omitted, the default port for the exporting connector will be used.
-
-Example IPv4:
-  ```yaml
-  destination = 10.11.14.2:2003 10.11.14.3:4242 10.11.14.4:2003
-  ```
-Example IPv6 and IPv4 together:
-```yaml
-destination = [ffff:...:0001]:2003 10.11.12.1:2003
-```
-When multiple servers are defined, Netdata will try the next one when the previous one fails.
-
-
-##### update every
-
-Netdata will add some randomness to this number, to prevent stressing the external server when many Netdata servers
-send data to the same database. This randomness does not affect the quality of the data, only the time they are sent.
-
-
-##### buffer on failures
-
-If the server fails to receive the data after that many failures, data loss on the connector instance is expected (Netdata will also log it).
-
-
-##### send hosts matching
-
-Includes one or more space separated patterns, using * as wildcard (any number of times within each pattern).
-The patterns are checked against the hostname (the localhost is always checked as localhost), allowing us to
-filter which hosts will be sent to the external database when this Netdata is a central Netdata aggregating multiple hosts.
-
-A pattern starting with `!` gives a negative match. So to match all hosts named `*db*` except hosts containing `*child*`,
-use `!*child* *db*` (so, the order is important: the first pattern matching the hostname will be used - positive or negative).
-
-
-##### send charts matching
-
-A pattern starting with ! gives a negative match. So to match all charts named apps.* except charts ending in *reads,
-use !*reads apps.* (so, the order is important: the first pattern matching the chart id or the chart name will be used,
-positive or negative). There is also a URL parameter filter that can be used while querying allmetrics. The URL parameter
-has a higher priority than the configuration option.
-
-
-##### send names instead of ids
-
-Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system and names
-are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several cases they are
-different : disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc.

-#### Examples
-
-##### Example configuration
-
-Basic example configuration for Prometheus remote write.
-
-```yaml
-[prometheus_remote_write:my_instance]
-    enabled = yes
-    destination = 10.11.14.2:2003
-    remote write URL path = /receive
-
-```
-##### Example configuration with HTTPS and HTTP authentication
-
-Add `:https` modifier to the connector type if you need to use the TLS/SSL protocol. For example: `remote_write:https:my_instance`.
-
-```yaml
-[prometheus_remote_write:https:my_instance]
-    enabled = yes
-    destination = 10.11.14.2:2003
-    remote write URL path = /receive
-    username = my_username
-    password = my_password
-
-```

-  prerequisites:
-    list:
-      - title: ''
-        description: |
-          - First [install](https://github.com/googleapis/google-cloud-cpp/) install Google Cloud Platform C++ Client Libraries
-          - Pub/Sub support is also dependent on the dependencies of those libraries, like `protobuf`, `protoc`, and `grpc`
-          - Next, Netdata should be re-installed from the source. The installer will detect that the required libraries are now available.
-  configuration:
-    file:
-      name: 'exporting.conf'
-    options:
-      description: |
-        The following options can be defined for this exporter.
-      folding:
-        title: 'Config options'
-        enabled: true
-      list:
-        - name: 'enabled'
-          default_value: 'no'
-          description: 'Enables or disables an exporting connector instance (yes|no).'
-          required: true
-        - name: 'destination'
-          default_value: 'pubsub.googleapis.com'
-          description: 'Accepts a space separated list of hostnames, IPs (IPv4 and IPv6) and ports to connect to. Netdata will use the first available to send the metrics.'
-          required: true
-          detailed_description: |
-            The format of each item in this list, is: [PROTOCOL:]IP[:PORT].
-            - PROTOCOL can be udp or tcp. tcp is the default and only supported by the current exporting engine.
-            - IP can be XX.XX.XX.XX (IPv4), or [XX:XX...XX:XX] (IPv6). For IPv6 you can to enclose the IP in [] to separate it from the port.
-            - PORT can be a number of a service name. If omitted, the default port for the exporting connector will be used.
-
-            Example IPv4:
-              ```yaml
-              destination = pubsub.googleapis.com
-              ```
-            When multiple servers are defined, Netdata will try the next one when the previous one fails.

-          required: false
-          detailed_description: |
-            Netdata will add some randomness to this number, to prevent stressing the external server when many Netdata servers
-            send data to the same database. This randomness does not affect the quality of the data, only the time they are sent.
-        - name: 'buffer on failures'
-          default_value: '10'
-          description: |
-            The number of iterations (`update every` seconds) to buffer data, when the external database server is not available.
-          required: false
-          detailed_description: |
-            If the server fails to receive the data after that many failures, data loss on the connector instance is expected (Netdata will also log it).
-        - name: 'timeout ms'

-            Hosts filter. Determines which hosts will be sent to the external database. The syntax is [simple patterns](https://github.com/netdata/netdata/tree/master/libnetdata/simple_pattern#simple-patterns).
-          required: false
-          detailed_description: |
-            Includes one or more space separated patterns, using * as wildcard (any number of times within each pattern).
-            The patterns are checked against the hostname (the localhost is always checked as localhost), allowing us to
-            filter which hosts will be sent to the external database when this Netdata is a central Netdata aggregating multiple hosts.
-
-            A pattern starting with `!` gives a negative match. So to match all hosts named `*db*` except hosts containing `*child*`,
-            use `!*child* *db*` (so, the order is important: the first pattern matching the hostname will be used - positive or negative).
-        - name: 'send charts matching'
-          default_value: '*'
-          description: |
-            One or more space separated patterns (use * as wildcard) checked against both chart id and chart name.
-          required: false
-          detailed_description: |
-            A pattern starting with ! gives a negative match. So to match all charts named apps.* except charts ending in *reads,
-            use !*reads apps.* (so, the order is important: the first pattern matching the chart id or the chart name will be used,
-            positive or negative). There is also a URL parameter filter that can be used while querying allmetrics. The URL parameter
-            has a higher priority than the configuration option.
-        - name: 'send names instead of ids'
-          default_value: ''
-          description: 'Controls the metric names Netdata should send to the external database (yes|no).'
-          required: false
-          detailed_description: |
-            Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system and names
-            are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several cases they are
-            different : disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc.
-        - name: 'send configured labels'
-          default_value: ''
