Information in this document applies to any platform.
The example shown is for Linux.


Example on Linux:

An alert is triggered when the metric "Disk Device Busy (%)" crosses a Critical or Warning threshold in Enterprise Manager 1(EM) 12c Cloud Control:

The alert is not cleared although the values obtained when running the OS command iostat -x are below both the Warning and Critical threshold settings.

The values reported by Enterprise Manager might appear to be very different than those reported by iostat.
