No. it is not weak. it is about 40% load averages, but somethig is happen and take of 100% CPU (see SNMP graph). And I got a problem in FreeBSD I can not obtain which process take all CPU (( > Robert Bonomi <bonomi@mail.r-bonomi.com> > It is unclear which process take CPU time. is there any other tool, which > help me to see processes that take CPU? >>One -obvious- anwser is the 'ps' commnd. >>Something like 'ps gxua".
