Add more checks to the cpu collector #7

Open erichte-ibm opened 3 years ago

erichte-ibm commented 3 years ago

The CPU collector should at least the following stats:

Alpha:

[ ] frequency (ppc64) - use ppc64_cpu --frequency
[ ] number of threads - lscpu
[ ] cpu model - lscpu or cat /proc/cpuinfo
[ ] cpu version/revision - same

1.0+ release:

[ ] SMT on/off - use either lscpu or ppc64_cpu --smt (optional? inferrable from num threads)
[ ] frequency (x86)
[ ] powersave/governor/etc
[ ] amount of cache (may belong in the memory section?)
[ ] physical vs virtual (perhaps in a new vm.rs collector group?)

consider nproc versus /proc/cpuinfo, for getting number of CPUs actually available to the process
