Does the grafana-agent output the OS version?

Does the agent output the OS type/version. For example RHEL 8.

AFAIK it displays the OS (linux, windows, etc) but not the distribution.

./agent -version
agent, version  (branch: , revision: )
  build user:
  build date:
  go version:       go1.18.3
  platform:         linux/amd64

What's the use case?

[nick-wvu]

Thank you for your reply, I should have added more info.
Does it send any of that to prometheus? I'm looking to make a table in grafana to display OS name/version.

Hey Nick! I suppose you mean the OS type and version of the host system that's running the Agent, right? The Agent's internal metrics do not include this information about the host system by default.

If your hosts are some flavor of Linux, you can use the node_exporter integration with the os collector which parses /etc/os-release or /usr/lib/os-release to retrieve this information. Take some time to read through the documentation to see the available list of collectors, as well as advice on how to set up the exporter correctly if you plan on running it on Docker or Kubernetes.

For macOS, the os collector is not implemented yet, but is tracked on this upstream ticket. For Windows machines you can use the equivalent windows_exporter which does have an os equivalent collector.

Does the grafana-agnet use the os collector from the node_exporter?

[tpaschalis]

Yes, the os collector is enabled by default when using node_exporter.

You can use the set_collectors key to run only this collector, if you don't need the other ones from the default set.

[nick-wvu]

OK, thank you. Any chance you happen to have the metric handy?
I don't see anything like node_os_info like there is for windows

integrations:
  agent:
    enabled: true
  node_exporter:
    enabled: true

The metric names are node_os_info and node_os_version. I'm going to close the tickets unless there's anything agent specific further to discuss here.
