I have a request to monitor any sudden growth on a number of file systems which are critical. The FS are not the same size however the utilization remains constant for most of the time unless there is an issue.
How do i setup a rule on live exceptions to do this using the deviation from normal rule.
I currently setup this rule but not sure if it will work.
Lets say the FS is on average 50% utilized, does this mean that an alert will be generated when the utilization grows above 5% of 50%. Or does it mean that an alarm will be generated when Partition Utilization passes 52,5%?
Hopefully the following Knowledge Base Articles help answer your questions.
