System Filesystem Metricset

edit

System Filesystem Metricset

edit

The System filesystem metricset provides file system statistics. For each file system, one document is provided.

This metricset is available on:

  • Darwin
  • FreeBSD
  • Linux
  • OpenBSD
  • Windows

Filtering

edit

Often there are mounted filesystems that you do not want Metricbeat to report metrics on. A simple strategy to deal with these filesystems is to configure a drop_event filter that matches the mount_point using a regular expression. Below is an example.

metricbeat.modules:
  - module: system
    period: 30s
    metricsets: ["filesystem"]
    filters:
      - drop_event.when.regexp.mount_point: '^/(sys|cgroup|proc|dev|etc|host)($|/)'

Fields

edit

For a description of each field in the metricset, see the exported fields section.

Here is an example document generated by this metricset:
