MongoDB Atlas cluster 🔗

Note: Use the MongoDB Atlas receiver in place of the SignalFx Smart Agent mongodb-atlas cluster monitor. The Smart Agent is deprecated. For details, see the deprecation notice.

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the mongodb-atlas monitor type by using the SignalFx Smart Agent Receiver.

MongoDB Atlas provides MongoDB as an on-demand fully managed service. Atlas exposes MongoDB cluster monitoring and logging data through its monitoring and logs REST API endpoints. These Atlas monitoring API resources are grouped into measurements for MongoDB processes, host disks, and MongoDB databases.

This monitor type repeatedly scrapes MongoDB monitoring data from Atlas at the configured time interval. It scrapes the process and disk measurements into metric groups called mongodb and hardware. The original measurement names are included in the metric descriptions.

A set of data points are fetched at the configured granularity and period for each measurement. Metric values are set to the latest non-empty data point value in the set. The finest granularity supported by Atlas is 1 minute. The configured period for the monitor type needs to be wider than the interval at which Atlas provides values for measurements, otherwise some of the sets of fetched data points will contain only empty values. The default configured period is 20 minutes, which works across all measurements and gives a reasonable response payload size.

Benefits 🔗

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

Installation 🔗

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.

Configuration 🔗

This monitor type is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector. You can use existing Smart Agent monitors as OpenTelemetry Collector metric receivers with the Smart Agent Receiver.

This monitor type requires a properly configured environment on your system in which you’ve installed a functional Smart Agent release bundle. The Collector provides this bundle in the installation paths for x86_64/amd64.

To activate this monitor type in the Collector, add the following lines to your configuration (YAML) file:

To activate this monitor type in the Splunk Distribution of OpenTelemetry Collector, add the following to your agent configuration:

    type: mongodb-atlas
    ...  # Additional config

To complete the activation, you must also include the smartagent/mongodb-atlas in a metrics pipeline. To do this, add the receiver item to the service/pipelines/metrics/receivers section of your configuration file. For example:

      receivers: [smartagent/mongodb-atlas]

Configuration settings 🔗

The following table shows the configuration options for the mongodb-atlas monitor type:








ProjectID is the Atlas project ID




PublicKey is the Atlas public API key




PrivateKey is the Atlas private API key




Timeout for HTTP requests to get MongoDB process measurements from Atlas. This should be a duration string that is accepted by func ParseDuration (default: 5s)




EnableCache enables locally cached Atlas metric measurements to be used when true. The metric measurements that were supposed to be fetched are in fact always fetched asynchronously and cached. (default: true)




Granularity is the duration in ISO 8601 notation that specifies the interval between measurement data points from Atlas over the configured period. The default is shortest duration supported by Atlas of 1 minute. (default: PT1M)




Period the duration in ISO 8601 notation that specifies how far back in the past to retrieve measurements from Atlas. (default: PT20M)
