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
