[Feature Request] Prometheus Endpoint

[19wolf]

I’d love to have an endpoint for Prometheus to scrape data from, such as chunks health, server usage, and other metrics available in the cgi-server.

I know that the main resources are focused on developing the basic functionality of the project. But it would really be great to have a Prometheus endpoint to collect metrics.

@19wolf @konstantin-921 do you use LizardFS commercially and your businesses have a need for such a feature? Just curious about this need, maybe we'll put that on the roadmap :)

[konstantin-921]

Yes, we use LizardFS in commercial development. Right now there is a need to add monitoring for LizardFS. We use prometheus exporters or integrated endpoints to collect any metrics. It would be cool if you could add an endpoint for prometheus metrics :)

[19wolf]

I do not use LizardFS commercially, and in fact no longer use it at home either (for now), but if I were to use it at work I would definitely need this

So far I have added "crutches". I'm running every minute requests via cron using lizardfs-admin. My cron job looks like this:

* * * * * sed -i 's/^chunks_availability .*/chunks_availability '$(/usr/bin/lizardfs-admin chunks-health <HOST> 9421 | awk 'NR==3{print $2}')'/g' /var/lib/node_exporter/textfile_collector/lizardfs.prom

Then I use Node Exporter Textfile Collector - https://github.com/prometheus/node_exporter#textfile-collector to handle this metrics. It's not the most convenient setup, but at least it works.

For some reason I don't see any new emails from you. Even the spam folder is empty. My email is konstantin-921@yandex.ru.
