Seeking assistance from the proc PMDA gurus ...


I am seeing this on lots of QA hosts:

kenj@vm12:~/src/pcp/qa$ pminfo -f proc.psinfo.ngid

proc.psinfo.ngid
Error: Unknown or illegal instance identifier

Values for all the other proc.psinfo metrics look to be OK (and only ngid produces this error).

Is this correct?

And then, less commonly:

proc.psinfo.cpusallowed: Unknown or illegal instance identifier

Is this correct?

In both cases, since I did not specify any instances, I would have expected "No data available" or a reason why no data was available.

I'm also seeing qa/999 failures with lines like:

hotproc.psinfo.cgroups: No data available

I suspect this one is OK, but just needs filtering in qa/999 ... does that sound right?
