Thanks for data.
I think the cpu usage alert was triggered by one of other cpu usage tests,
which you have in your monit configuration file:
if cpu usage (user) > 75% for 1 cycles then alert
if cpu usage (system) > 65% for 1 cycles then alert
if cpu > 0% for 5 cycles then alert
There are three independent tests in the config:
1.) "cpu usage (user)"
2.) "cpu usage (system)"
3.) "cpu"
The CPU test #3 (with no options) will check total CPU usage (usr% + sys% +
wait%). Tests #1 test usr% only, and #2 tests sys% only.
Only the check #3 has the 5 cycles constraint, the other will alert during
first cycle.
Best regards,
Martin
