Hi Igor,
the operating system is RHEL6 and monit version is 5.3.1
this is what i have in my config
if cpu usage (user) > 70% then alert
if cpu usage (system) > 30% then alert
if cpu usage (wait) > 20% then alert
this is one of the errors
Description: cpu system usage of 50.0% matches resource limit [cpu system
usage>30.0%]
this is what i get in /var/log/messages
Dec 6 12:01:29 <hostname-removed> monit[864]: <hostname-removed> cpu
system usage of 50.0% matches resource limit [cpu system usage>30.0%]
Dec 6 12:02:29 <hostname-removed> monit[864]:
<hostname-removed><hostname-removed>' cpu system usage check succeeded
[current cpu system usage=0.9%]
this is the output of ps --no-headers -A -o "%*cpu* sz ucomm" | sort -k1nr
| head -20

Have to say i am at a total loss as there is no way the usage figures are
accurate.
If there is any other info i can supply that will be useful please let me
know.
Regards
Wayne
