| 10 | +The NGNINX receiver fetches stats from a Nginx instance using the ``ngx_http_stub_status_module`` module's status endpoint. The supported pipeline type is ``metrics``. See :ref:`otel-data-processing` for more information. |

| 20 | + |
| 21 | + |
| 22 | + |
| 23 | + |
| 24 | +The receiver collects stats with MongoDB's ``dbStats`` and ``serverStatus`` commands, and uses the golang mongo driver. See more at :new-page:`Mongo Go driver documentation <https://github.com/mongodb/mongo-go-driver>`. |
| 25 | + |
| 26 | +.. note:: Use the MongoDB receiver in place of the deprecated SignalFx Smart Agent ``mongodb`` monitor type. |
| 27 | + |
| 28 | +Prerequisites |
| 29 | +====================== |
| 30 | + |
| 31 | +The MongoDB receiver supports MongoDB versions 4.0+ and 5.0. |
| 32 | + |
| 33 | +MongoDB recommends to set up a least privilege user (LPU) with a ``clusterMonitor`` role in order to collect metrics. |
| 34 | + |
| 35 | +* For information on MongoDB's roles, see :new-page:`MongoDB built-in roles <https://www.mongodb.com/docs/v5.0/reference/built-in-roles/#mongodb-authrole-clusterMonitor>`. |
| 36 | +* For an example of how to configure these permissions, see :new-page:`lpu.sh <https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/mongodbreceiver/testdata/integration/scripts/lpu.sh>`. |
| 37 | + |
| 38 | +.. note:: If you're using automatic discovery with MongoDB, see :ref:`linux-third-party-mongodb`. |
| 39 | + |
| 40 | +Get started |
| 41 | +====================== |
| 42 | + |
| 43 | +Follow these steps to configure and activate the component: |
| 44 | + |
| 45 | +1. Deploy the Splunk Distribution of the OpenTelemetry Collector to your host or container platform: |
| 46 | + |
| 47 | + - :ref:`otel-install-linux` |
| 48 | + - :ref:`otel-install-windows` |
| 49 | + - :ref:`otel-install-k8s` |
| 50 | + |
| 51 | +2. Configure the receiver as described in the next section. |
| 52 | +3. Restart the Collector. |
| 53 | + |
| 54 | +Sample configurations |
| 55 | +--------------------------- |
| 56 | + |
| 57 | +To activate the MongoDB receiver, add ``mongodb`` to the ``receivers`` section of your configuration file, as shown in the following example: |
| 58 | + |
| 59 | +.. code:: yaml |
| 60 | +
|
| 61 | + receivers: |
| 62 | + mongodb: |
| 63 | + hosts: |
| 64 | + - endpoint: localhost:27017 |
| 65 | + transport: tcp |
| 66 | + username: otel |
| 67 | + password: ${env:MONGODB_PASSWORD} |
| 68 | + collection_interval: 60s |
| 69 | + initial_delay: 1s |
| 70 | + tls: |
| 71 | + insecure: true |
| 72 | + insecure_skip_verify: true |
| 73 | +
|
| 74 | +To complete the configuration, include the receiver in the ``metrics`` pipeline of the ``service`` section of your configuration file. For example: |
| 75 | + |
| 76 | +.. code:: yaml |
| 77 | +
|
| 78 | + service: |
| 79 | + pipelines: |
| 80 | + metrics: |
| 81 | + receivers: [mongodb] |
| 82 | +
|
| 83 | +Configuration options |
| 84 | +-------------------------------------------- |
| 85 | + |
| 86 | +The following settings are optional: |
| 87 | + |
| 88 | +* ``hosts``. ``[localhost:27017]`` by default. List of ``host:port`` or Unix domain socket endpoints. |
| 89 | + |
| 90 | + * For standalone MongoDB deployments this is the hostname and port of the mongod instance. |
| 91 | + |
| 92 | + * For replica sets specify the hostnames and ports of the mongod instances that are in the replica set configuration. If the ``replica_set`` field is specified, nodes will be autodiscovered. |
| 93 | + |
| 94 | + * For a sharded MongoDB deployment, specify a list of the ``mongos`` hosts. |
| 95 | + |
| 96 | +* ``username``: If authentication is required, provide the ``clusterMonitor`` permissions here. |
| 97 | + |
| 98 | +* ``password``: If authentication is required, provide the password here. |
| 99 | + |
| 100 | +* ``collection_interval``. ``1m`` by default. This receiver collects metrics on an interval. Valid time units are ``ns``, ``us`` (or ``µs``), ``ms``, ``s``, ``m``, ``h``. This value must be a string readable by Golang's time parseDuration. Learn more at :new-page:`ParseDuration <https://pkg.go.dev/time#ParseDuration>`. |
| 101 | + |
| 102 | +* ``initial_delay``. ``1s`` by default. Defines how long this receiver waits before starting. |
| 103 | + |
| 104 | +* ``replica_set``: If the deployment of MongoDB is a replica set, use this to specify the replica set name which allows for autodiscovery of other nodes in the replica set. |
| 105 | + |
| 106 | +* ``timeout``. ``1m`` by default. The timeout of running commands against mongo. |
| 107 | + |
| 108 | +* ``tls``: TLS control. By default insecure settings are rejected and certificate verification is on. See more at :new-page:`TLS Configuration Settings <https://github.com/open-telemetry/opentelemetry-collector/blob/main/config/configtls/README.md>`. |
