Adding Prometheus users as well.

Hi everyone,

By some historic accident I became the maintainer of the collectd exporter (https://github.com/prometheus/collectd_exporter), although I have never used collectd myself and know very little about it. This has led to some neglect from my side...

Does anyone feel invested in collectd and feels qualified to maintain it?

Cheers,
Julius

Collectd has a built-in prometheus exporter, so I don't know if this is still necessary?

That's a good question - googling I found https://collectd.org/wiki/index.php/Plugin:Write_Prometheus, which says:

"This plugin is similar in scope to the collectd_exporter written by the Prometheus team and uses the same naming schema so it can be used as a drop-in alternative."

So maybe we could indeed deprecate the Collectd Exporter. I'm just not familiar enough with Collectd to say for sure if the exporter is doing anything important over that plugin.

+cc Florian Forster, who was involved in both - maybe you can provide more insight?

Awesome, thanks for the insight, Florian!

I suggest to mark the collectd_exporter then, and move it into our junkyard organization after a while of nobody complaining. I'll send a PR for that.

Hi Julius, hi Harald, hi lists,

I'm not aware of anything that the collectd_exporter does that the
"write_prometheus" plugin doesn't support – and I'm happy to get the
plugin to feature parity if anything comes up.

When switching to the plugin, a collectd_exporter that is running
alongside collectd (like a sidecar or some such) can be removed. A
collectd_exporter that is running centrally (many collectd's, one
exporter) can be replaced by a collectd or Prometheus instance. Either
way, the overall complexity of the setup is reduced. (*)

Hope this helps :)
Best regards,

(*) In theory. I'm not operating such a setup myself.
