Free disk space (filesystems) 🔗

Note

If you are using the Splunk Distribution of OpenTelemetry Collector and want to collect file system utilization metrics, use the native OTel component Host metrics receiver.

Configuration settings 🔗

The following table shows the configuration options for this monitor.

Option	Required	Type	Description
`hostFSPath`	no	`string`	Path to the root of the host filesystem. It is useful when running in a container and the host filesystem is mounted in a subdirectory under /. The disk usage metrics emitted will be based at this path.
`fsTypes`	no	`list of strings`	The filesystem types to include/exclude. This is an overridable set. If this is not set, the default value is the set of all non-logical/virtual filesystems on the system. On Linux this list is determined by reading the `/proc/filesystems` file and choosing the filesystems that do not have the `nodev` modifier.
`mountPoints`	no	`list of strings`	The mount paths to include/exclude. This is an overridable set. Note: If you are using the hostFSPath option, do not include the `/hostfs/` mount in the filter. If both this and `fsTypes` are specified, the two filters combine in an AND relationship.
`sendModeDimension`	no	`bool`	Set to `true` to emit the “mode” dimension, which represents whether the mount is “rw” or “ro”. (default: `false`)
