Collectd df 🔗

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the Collectd df monitor type to track free disk space on the host using the collectd df plugin.

This integration is only available on Linux. Note a file system must be mounted in the same file system namespace that the agent is running in for this monitor to be able to collect statistics about that file system. This might be an issue when running the agent in a container.

Benefits 🔗

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

  • View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. For information about dashboards, see View dashboards in Observability Cloud.

  • View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Splunk Infrastructure Monitoring navigators.

  • Access the Metric Finder and search for metrics sent by the monitor. For information, see Use the Metric Finder.

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 🔗

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 🔗

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

    type: collectd/df
    ... # Additional config

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

      receivers: [smartagent/collectd/df]

Configuration settings 🔗

The following table shows the configuration options for the collectd/df monitor:








Path to the root of the host file system. Useful when running in a container and the host filesystem is mounted in some subdirectory under /.




If true, the file systems selected by fsTypes and mountPoints are excluded, and all others are included. The default value is true.



list of strings

The file system types to include or exclude. The default values is [aufs overlay tmpfs proc sysfs nsfs cgroup devpts selinuxfs devtmpfs debugfs mqueue hugetlbfs securityfs pstore binfmt_misc autofs].



list of strings

The mount paths to include or exclude, interpreted as a regular expression if surrounded by /. Note that you need to include the full path as the agent sees it, irrespective of the hostFSPath option. The default value is [/^/var/lib/docker/ /^/var/lib/rkt/pods/ /^/net// /^/smb//].




The default value is false.




The default value is false.




Whether true percent based metrics are reported. The default value is false.

Notes 🔗

  • Learn more about the available metric types in Observability Cloud.

  • Default metrics are those metrics included in host-based subscriptions in Observability Cloud, such as host, container, or bundled metrics. Custom metrics are not provided by default and might be subject to charges. See more about metric categories.

  • To add additional metrics, see how to configure extraMetrics using the Collector.
