$ gluster-stats --help
usage: gluster-stats [-h] [--record] [--version] [--timeout TIMEOUT]

Collect stats related to gluster

optional arguments:

  --record           Record the gluster cli responses in a local response file
  --version          show program's version number and exit
  --timeout TIMEOUT  Timeout per command in seconds. Defaults to 300.

Example output:

$ sudo gluster-stats

The following commands are run and parsed to generate the json output:

  • gluster --version
  • gluster peer status
  • gluster volume list
  • pidof glusterd
  • pidof glusterfsd

For each volume, the following commands are run:

  • gluster volume heal <volume> info
  • gluster volume heal <volume> info split-brain
  • gluster volume status <volume> detail

When run with --sudo, the gluster commands that require sudo access (all but --version) are run with sudo prepended.


Run make test

Tests are run locally with generated mock response files. Run gluster-stats-generate to generate new mock response file. The file will be saved at gluster_stats_<gluster_version>.json.


gluster-stats uses semantic versioning. Backward incompatible changes to the json output (such as changing something from a list to a dict) require a major version bump. New values in a dictionary will come with a minor version bump. Bug fixes and patches will use a patch bump.


  • Use the secret --xml option with gluster volume status - status was hard to parse and the parser is probably fragile. This will require new mock test files.
  • Additional health checks?
