Collect process metrics

[jszwedko]

A user requested the ability to record metrics by process (like CPU, memory, etc.).

I think this could be a separate source or incorporated into the host_metrics source.

I would love to see this

[LeeTeng2001]

Currently I rely on vector host metrics to scrape details about host machine, it's awesome as I don't need another agent like node scrapper to provide this information

[LeeTeng2001]

can i get my hands on this?

Sure!

Hi, since heim wouldn't be replaced in a short while, I cannot implement process metrics using heim crates. can we use both dependencies and only sysinfo for process metrics?

[LeeTeng2001]

In other word, should I make a PR that only uses sysinfo for process metrics or a PR with heim completely replaced?

[LeeTeng2001]

I already got a working sample, thanks for the kind & quick response! Vector is a great software, would love to contribute

Hi @LeeTeng2001, first of all, thank you for your interest in contributing!

I think it is fine using sysinfo to implement things that heim doesn't support.

Regarding the heim vs sysinfo debate, the only concern IMO if sysinfo can satisfy all metrics produced by the host_metrics source.

It is obvious that sysinfo is significantly more popular now and generally I would be in favor of using it going forward. But that will require some extra work and validation.

And yes, ideally we should only use one dependency.

I would like to remove heim but I fell like it would be too much of a PR & out of this issue scope, I'd like to keep the PR small and only implement process metrics for now.

This issue is closed, may I asked when will the next release be? I would love to use this feature

The next release is 0.43. Expected to happen on Dec 2nd. You can see this via the milestone. Also, you can see our public calendar.vector.dev
