EM 12c: Alerts for the Enterprise Manager 12c Cloud Control Host Metric Disk Device Busy (%) Are Not Cleared or Seem Wrong
Last updated on MARCH 09, 2018
Applies to:Enterprise Manager Base Platform - Version 188.8.131.52.0 and later
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.
