Add Gearman exporter

Why are you unregistering the processes and Go collectors? You still want to monitor the exporter itself.

Version information should not be added as a label on gearman_up, that'd be quite annoying to deal with. Put the label on a separate metric.

gearman_status_total is a gauge, and should thus not end in _total. Something like gearman_jobs_queued would be a better name.

[brian-brazil]

Keep it sorted.

Thanks for the feedback! I will fix it and then get back to you.

gearman_jobs_queued could be a bit misleading, as the metric actually represents all non-finished jobs, the ones queued for execution as well as the ones currently being executed.
I would suggest the following names:

• gearman_running_jobs
• gearman_total_jobs (while I don't like "total" very much, it is well established from gearman)
• gearman_workers

@brian-brazil wdyt?

gearman_total_jobs (while I don't like "total" very much, it is well established from gearman)

Everything in metrics is some form of total, it rarely adds anything to a metric name.

_jobs and _jobs_running would be the usual way to organise that.

@brian-brazil I went with your suggestion. Could you take another look?

[brian-brazil]

You still have the version label on up, that should be moved to a different metric.

[njam]

I split it into two metrics, as you recommend in your blogpost:

gearman_up 1
gearman_version_info{version="1.1.18"} 1

Did I miss some place to update it?

[brian-brazil]

Odd, it was missing when I had last looked.
