Collectd df 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the collectd/df monitor type by using the SignalFx Smart Agent Receiver.

Use this integration to track free disk space on the host using the collectd df plugin.

This monitor is 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 using the built-in dashboard. 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 Metric Finder and search for metrics sent by the monitor. For information about Metric Finder, 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 🔗

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:

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

To complete the integration, include the Smart Agent receiver using this monitor in a metrics pipeline. To do this, add the receiver to the service > pipelines > metrics > receivers section of your configuration file.

service:
  pipelines:
    metrics:
      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.
reportInodes no bool The default value is false.
