I am about initial gstat behavior: you can't be do `gstat >
output_log`, wait hour, press ^C and analyse output -- gstat exit
after one ineration. I am talk all utilites have different behavior --
some exits by pressing 'q', some only by ^C (systat), some can be infinitly
output to file|pipe, some -- not. Some have looped mode, some -- not,
some can handle multiple obejcts (gstat, iostat), some -- not (netstat
-nbI).
And more: ix show network statics in netmap mode, igb -- don't show.
No unification. This is more vital, I think.
And no tools for collect correlation data -- for example collect at
same time CPU load by core, i/o load by disk and network load by
inetrface. You may talk about Graphite, but graffit is crap:
