sum by, irate and __name__ question

[matejkramny]

What did you do?

I have data like:

system_cpu_system
system_cpu_user
system_cpu_steal
...

sum by(__name__)(irate({__name__=~"system_cpu_(system|user|steal|softirq|nice|iowait)"}[10s]))

What did you expect to see?

sum by(__name__)({__name__=~"system_cpu_(system|user|steal|softirq|nice|iowait)"})

What did you see instead? Under which circumstances?

The __name__ label (?) gets lost when using the irate function. There is ingestable data by irate as you can see:

I think I might not be doing this right, or this might be a bug.. I don't know how better to ask. I looked through numerous docs and tried many variations. Please help!

I can do this manually, but I'd like to know how it's possible using sum by

When you apply a function to a metric, it's no longer that metric. Thus the name is removed. You need to do this by hand as you've figured out.

I'd suggest using the node exporter to get these metrics, as it has labels which make the processing easier.

Ok I see. My targets are firehol/netdata.

Thanks for responding & making this awesome project!
