Hi Michele,

Hi all,

while for most hinv.* metrics I do not expect any changes over time
(hinv.pagesize, hinv.ncpu, ...), I was a bit surprised that also
hinv.cpu.clock seems to not change over time (F21 updated today, here).

The original code was written before CPU clock throttling,
cstates and so forth, and hence didn't expect the clock to
change. It does nowdays! Attached patch should fix it (untested
but should be fine). I'll also need to check if the default
pmlogger config only logs hinv.cpu.clock once - that might
need an update too, and of course some QA.

Regards
