Collectd df (deprecated)

Use this Splunk Observability Cloud integration for the Collectd df plugin monitor. See benefits, install, configuration, and metrics

Note: This integration is deprecated in favor of Free disk space (filesystems).

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 Splunk 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 Use navigators in Splunk Infrastructure Monitoring.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Search the Metric Finder and Metadata Catalog.

- For a list of common configuration options, refer to Common configuration settings for monitors.
- Learn more about the Collector at Get started: Understand and use the Collector.

Example

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

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

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

service:
  pipelines:

      receivers: [smartagent/collectd/df]

Configuration settings

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


Option	Required	Type	Description
`hostFSPath`	no	`string`	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 `/.`
`ignoreSelected`	no	`bool`	If true, the file systems selected by `fsTypes` and `mountPoints` are excluded, and all others are included. The default value is `true`.
`fsTypes`	no	`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]`.
`mountPoints`	no	`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//]`.
`reportByDevice`	no	`bool`	The default value is `false`.
