I setup threshold of processor and cpu in the DFM. For example, I changed "Processor utilization threshold" as 60%. LMS would send alart email if CPU of core switch is beyond it.But i have not received any alert for a long time,so I log on the core switch and type "show process cpu history". In " CPU% per minute (last 60 minutes)", I could find that beyond threshold was happened in this chart (maximum CPU% is beyond 60 %,but average CPU% is not).I want to know why I did not receive any alert.
BTW, I tried to decrease threshold as 1% only for test purpose. Lots of alert could come in.
