Docker Metric

[lanrekkeeg]

Is there a way to convert the docker metric cpu_used value to percentage in docker metric plugin? because this value doesn't make any sense until converted to percentage. Any formula or workaround will be appreciated.

Lua filter? Maybe a script that updates it that way?

Probably worth creating a new plugin based on Prometheus standards here, @lanrekkeeg is that something you would be open to contribute?

[lanrekkeeg]

yes, we need to create this new plugin accordingly. I am willing to contribute from next month (July) onward.

@lanrekkeeg awesome if you can contribute, I would recommend looking at the NGINX metric plugin as a starter.

Additionally, you may be able to get away with using the Prometheus Scraper and configuring Docker to expose Prometheus Metrics: https://docs.docker.com/config/daemon/prometheus/

@lanrekkeeg would this still be something you would be open to contribute?

@agup006 Yes, I had 2 exams left which I will be giving this month. After this, I will start working on this. I will look into your suggestion.
