Commands

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.

Testing

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.

Versioning

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.

Todo

• 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?
