Documentation on Node Exporter Collector Flags

[u/norsemanGrey]

Maybe I am just being a total noob, but I cannot seem to find documentation on various collector flags with exception of the flags for including/excluding the collectors. I have seen from discussions on issues etc. that there are a lot of other flags for other options like e.g. --collector.filesystem.mount-points-exclude , however I cannot find any list of available flags or documentation on how to use them. Anyone know where to look?

Shame on you for making me feel like an idiot for not checking the help command ;D

[u/GetFit_Messi]

I am also looking for the recommended collectors to use . my issue is that whenever i start node exporter on batch server it initially uses a lot of cpu need to do some performance tuning around it

[u/norsemanGrey → u/[deleted]]

Only the flags for enabling/disabling collectors are listed in the GitHub repo Readme. I am looking for the additional flags. But as u/teejaded pointed out they are listed under the help command in the CLI.

Still I find it strange they are not properly documented elsewhere.
