MongoDB πŸ”—

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the MongoDB monitor type to capture the following metrics about MongoDB:

  • Memory

  • Network input/output bytes count

  • Heap usage

  • DB connections

  • Operations count

  • Active client connections

  • Queued operations

The plugin also captures the following DB-specific metrics:

  • DB size

  • DB counters

Prerequisites πŸ”—

The following applies:

  • This integration is only available on Kubernetes and Linux.

  • This integration requires MongoDB 2.6 or higher.

  • This integration is not supported for Splunk OTel Collector versions 0.99.0 or higher. Use the MongoDB receiver instead.

Benefits πŸ”—

After you configure the integration, you can access these features:

Installation πŸ”—

Follow these steps to deploy this integration:

  1. Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:

  2. Configure the monitor, as described in the Configuration section.

  3. Restart the Splunk Distribution of OpenTelemetry Collector.

Authentication πŸ”—

If you’re monitoring a secured MongoDB deployment, create a MongoDB user with minimal read-only roles, as follows:

db.createUser( {
  user: "<username>",
  pwd: "<password>",
  roles: [ { role: "readAnyDatabase", db: "admin" }, { role: "clusterMonitor", db: "admin" } ]
});

Note

Only SCRAM-SHA-1 authentication is supported.

Configuration πŸ”—

To use this integration of a Smart Agent monitor with the Collector:

  1. Include the Smart Agent receiver in your configuration file.

  2. Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.

Example πŸ”—

To activate this integration, add the following to your Collector configuration:

receivers:
  smartagent/mongodb:
    type: collectd/mongodb
    ...  # Additional config

Next, add the monitor to the service.pipelines.metrics.receivers section of your configuration file:

service:
  pipelines:
    metrics:
      receivers: [smartagent/mongodb]

Configuration settings πŸ”—

The following table shows the configuration options for the MongoDB monitor:

presents. Not needed if not using TLS or if MongoDB certificate is signed by a globally trusted issuer already installed in the default location on your system.

tlsClientCert

No

string

Path to a client certificate. Not needed unless your MongoDB

instance requires x509 client verification.

tlsClientKey

No

string

Path to a client certificate key. Not needed unless your MongoDB

instance requires x509 client verification, or if your client certificate defined in tlsClientCert includes the key.

tlsClientKeyPassPhrase

No

string

Passphrase for the TLS client key defined in tlsClientKey.

sendCollectionMetrics

No

bool

Whether to send collection level metrics or not. The default

value is false.

sendCollectionTopMetrics

No

bool

Whether to send collection level top timing metrics or not. The

default value is false.

Note

When using TLS authentication, SCRAM-SHA-256 is not supported. Use SCRAM-SHA-1 authentication.

Custom metrics are not provided by default and might be subject to charges. See Metric categories for more information.

  • In MTS-based subscription plans, all metrics are custom.
