Description:

collectdeos 0.2.1

Collectd plugin to collect EOS metrics.
Connects to a mgm instance using eos client and publishes node, fs and space metrics.
Collectd config section example:
<Plugin python>
Import collectd_eos
<Module collectd_eos>
instance example root://eos.example
instance another root://another.eos.instance.example
instance third root://third.mgm.intance.example
interval 60
eos_client_command ssh client.host.example eos
</Module>
</Plugin>

instance expects 2 values:

EOS instance name / plugin instance name
EOS MGM URL


interval overrides the default collection interval
eos_client_command is used when there is no eos client on the collectd node,
and ssh or docker are needed to run eos, especially during plugin development

If there are no instances defined in config and $EOS_MGM_URL is set,
it is used as the default url with the instance name set to the hostname portion.
If there are no instances defined in config and $EOS_MGM_URL is unset,
the current hostname is used as the instance name and url.

Testing
Test in virutalenv:
virtualenv venv
. venv/bin/activate
pip install -r build-requirements.txt -r test-requirements.txt
pip install -e .
pytest
python setup.py sdist bdist_wheel
twine check dist/*
tox
Use collectd.conf or collectd.docker.conf for functional testing: does the plugin cope with real metrics?
On a host with eos:
$ collectd -Tf -C collectd.conf
Docker can be used for the eos client:
$ docker run --name eos_client --rm -itd gitlab-registry.cern.ch/dss/eos:4.4.10
<container id output>
$ docker exec -it eos_client kinit <username>@CERN.CH
<password prompt>
$ collectd -Tf -C collectd.docker.conf
<check collectd log for errors>
$ docker stop eos_client

Added

pyproject.toml to define build requirements as per PEP-518
build-requirements.txt and build-requirements.26.txt to document build requirements

Changed

Configuration section format. mgm_url key is removed
EOS instances are now defined by the key “instance” which expects two values:

Fixed

Don’t sent interval of -1 to collectd, it does not interpret it as default
