Free disk space (filesystems) πŸ”—


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 πŸ”—

The following table shows the configuration options for this monitor.








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.



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.



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.




Set to true to emit the β€œmode” dimension, which represents whether the mount is β€œrw” or β€œro”. (default: false)
