== MongoDB module

This module periodically fetches metrics from https://www.mongodb.com[MongoDB]
servers.

[float]
=== Module-specific configuration notes

When configuring the `hosts` option, you must use MongoDB URLs of the following
format:

-----------------------------------
[mongodb://][user:pass@]host[:port][?options]
-----------------------------------

The URL can be as simple as:

[source,yaml]
----------------------------------------------------------------------
- module: mongodb
  hosts: ["localhost"]
----------------------------------------------------------------------

Or more complex like:

[source,yaml]
----------------------------------------------------------------------
- module: mongodb
  hosts: ["mongodb://myuser:mypass@localhost:40001", "otherhost:40001"]
----------------------------------------------------------------------

The username and password can be included in the URL or they can be set using
the respective configuration options. The credentials in the URL take precedence
over the username and password configuration options.

[source,yaml]
----
- module: mongodb
  metricsets: ["status"]
  hosts: ["localhost:27017"]
  username: root
  password: test
----

The default metricsets are `collstats`, `dbstats` and `status`.

[float]
=== Compatibility

The MongoDB metricsets were tested with MongoDB 3.4 and 3.0 and are expected to
work with all versions >= 2.8.


[float]
=== Example configuration

The MongoDB module supports the standard configuration options that are described
in <<configuration-metricbeat>>. Here is an example configuration:

[source,yaml]
----
metricbeat.modules:
- module: mongodb
  metricsets: ["dbstats", "status", "collstats", "metrics", "replstatus"]
  period: 10s
  enabled: true

  # The hosts must be passed as MongoDB URLs in the format:
  # [mongodb://][user:pass@]host[:port].
  # The username and password can also be set using the respective configuration
  # options. The credentials in the URL take precedence over the username and
  # password configuration options.
  hosts: ["localhost:27017"]

  # Optional SSL. By default is off.
  #ssl.enabled: true

  # Mode of verification of server certificate ('none' or 'full')
  #ssl.verification_mode: 'full'

  # List of root certificates for TLS server verifications
  #ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]

  # Certificate for SSL client authentication
  #ssl.certificate: "/etc/pki/client/cert.pem"

  # Client Certificate Key
  #ssl.key: "/etc/pki/client/cert.key"

  # Username to use when connecting to MongoDB. Empty by default.
  #username: user

  # Password to use when connecting to MongoDB. Empty by default.
  #password: pass
----

This module supports TLS connections when using `ssl` config field, as described in <<configuration-ssl>>.
