redfish enable/disable specific metrics categories

[rismoney]

Use Case

It can be quite expensive on big systems to query thermals, power, voltage, etc.

Expected behavior

Be able to just enable power collection

Actual behavior

You get all metrics thermals, power, voltage.

Additional info

Not sure what the best way to do this, but filtering, if I understand correctly is performed after the input is collected, and doesn't alleviate the https queries going out for all the additional calls.

Hi,

Looking at the Gather function, there really is only two things we could break this down into:

• Thermal - which produces temperatures and fans
• Power - which produces power control, power supplies, and voltages

Generally, we have a config option that is used to specify which parts you would want to collect. Something like:

## Specify the metrics to collect
# collection = ["thermal", "power"]

You could possibly also disable the call to getChassis if the tagSetChassisLocation is not set.

Is this what you are after? Would you be willing to put up a PR?

That is definitely what I am after!

collection = ["power"] would totally work and reduce a huge burden across the 1000s of systems interrogated. Unfortunately I don't think I can contribute a PR at this time.

I put up a quick PR in #14143. In 20-30mins there will be artifacts attached to that PR that you could download. Could you give the new option a try and confirm you get what you expect:

include_metrics = ["power"]

Thanks!

Wow that was fast! I will attempt to do this now. Will report back shortly.

I tested exactly this, and it worked 100% as expected! I am so thankful and kudos to you!
