+# 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

+In `average` or `sum` data sources, all values are normalized and are reported to Prometheus as gauges. Now, use the
+'expression' text form in Prometheus. Begin to type the metrics we are looking for: `netdata_system_cpu`. You should see
+that the text form begins to auto-fill as Prometheus knows about this metric.

+For more information check Prometheus documentation.
+
+### 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
+
+ rules:
+ - alert: node_high_cpu_usage_70
+ expr: sum(sum_over_time(netdata_system_cpu_percentage_average{dimension=~"(user|system|softirq|irq|guest)"}[10m])) by (job) / sum(count_over_time(netdata_system_cpu_percentage_average{dimension="idle"}[10m])) by (job) > 70

+##### 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.

+##### 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]

+
+
+Use the Prometheus remote write exporting connector to archive your Netdata metrics to the external storage provider of your choice for long-term storage and further analysis.
+
+
+<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
+
+## Limitations
+
+The remote write exporting connector does not support buffer on failures.
+
+
+## Setup
+
+### Prerequisites
+
+####
+
+- Netdata and the external storage provider of your choice, installed, configured and operational.
+- `protobuf` and `snappy` libraries installed.
+- Netdata reinstalled after the libraries.
+
+
+
+### 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 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

+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.

+##### 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`.

+
+## Limitations
+
+The remote write exporting connector does not support buffer on failures.
+
+
+## Setup
+
+### Prerequisites
+
+####
+
+- Netdata and the external storage provider of your choice, installed, configured and operational.
+- `protobuf` and `snappy` libraries installed.
+- Netdata reinstalled after the libraries.
+
+
+
+### 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 |

+| 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 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*`,

+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.

+##### 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.

+
+
+<img src="https://netdata.cloud/img/prometheus.svg" width="150"/>
+
+
+Use the Prometheus remote write exporting connector to archive your Netdata metrics to the external storage provider of your choice for long-term storage and further analysis.
+
+
+<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
+
+## Limitations
+
+The remote write exporting connector does not support buffer on failures.
+
+
+## Setup
+
+### Prerequisites
+
+####
+
+- Netdata and the external storage provider of your choice, installed, configured and operational.
+- `protobuf` and `snappy` libraries installed.
+- Netdata reinstalled after the libraries.
+
+
+
+### 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.
+
+

+
+#### 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

+
+## Limitations
+
+The remote write exporting connector does not support buffer on failures.
+
+
+## Setup
+
+### Prerequisites
+
+####
+
+- Netdata and the external storage provider of your choice, installed, configured and operational.
+- `protobuf` and `snappy` libraries installed.
+- Netdata reinstalled after the libraries.
+
+
+
+### 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.

+##### 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

+ 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]

+
+
+Use the Prometheus remote write exporting connector to archive your Netdata metrics to the external storage provider of your choice for long-term storage and further analysis.
+
+
+<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
+
+## Limitations
+
+The remote write exporting connector does not support buffer on failures.
+
+
+## Setup
+
+### Prerequisites
+
+####
+
+- Netdata and the external storage provider of your choice, installed, configured and operational.
+- `protobuf` and `snappy` libraries installed.
+- Netdata reinstalled after the libraries.
+
+
+
+### 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>

+| 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 |

+Example IPv6 and IPv4 together:
+```yaml
+destination = [ffff:...:0001]:2003 10.11.12.1:2003
