gluster-stats is a command-line utility that generates health-related gluster
statistics in json, for use in monitoring gluster.

Installation
------------

``pip install gluster-stats``

Usage
-----

Return gluster stats in json format. Requires root privileges.

Options::

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

    Collect stats related to gluster

    optional arguments:
      -h, --help         show this help message and exit
      --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
    {

     "volume_count": 1, 
     "volumes": [
      "preprodcomms"
     ]
    }

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?
