+<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/netdata-agent/configuration.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/src/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
+
+```
