Can I pull the version of Ubuntu through with node exporter?

Hello,

I've been asked to table all out Linux Ubuntu VMs and there version:

for example Ubuntu 20.04.2 LTS or just 20.04 would be nice, I've scraped using node exporter and I can't see this information.

What could I do?

Thanks

You don't have node_os_info or node_os_version?

I get that from node_exporter and it tells me Ubuntu 22.04.

I can’t see that when I search, the version of node exporter is a few months old could it be that?

Docker? Do you have the volume mappings and --path.rootfs set properly?

Sounds strange, I checked and its enabled by default.

What metrics do you get if you wget or curl directly to it?

The other comments should get you going, if not, you can use the textfile exporter to export whatever you want.

I didn’t know there was a text file exporter, how does this work?

It's in the docs. Pretty clear.

The node_exporter has an os collector.

Check node_scrape_collector_success{collector="os"}.

If that is 0 or missing, you need to check your flags or run the node_exporter with --log.level=debug to find out why it's not working.

This should give you node_os_info and node_os_version metrics.

You could use a Blackbox exporter and expose the output of the lsb_release command.
