Monit not alerting when CPU cycle surpasses 90%

[None]

After installing Monit from the repos, I added the following to the config file to alert on a service when it surpasses 90% CPU utilization continuously, for an extended period of time. The problem is that Monit's not working as it should.

check process .office

          matching ".office"

          if cpu usage > 90% for 10 cycles then alert
