Last updated on AUGUST 03, 2017

Applies to:

Information in this document applies to any platform.

Symptoms

Host metric data in Enterprise Manager (EM) 12c Cloud Control is being collected in real time, however history data is no longer being stored.
Using the CPU Details page in EM 12c, for instance:

Targets > Hosts > [select Host Target link] > [expand Host pull down menu] > Monitoring > CPU Details

Charts for the CPU Utilization, CPU I/O Wait and CPU Load metrics are displayed.

Charts for all of these metrics show the real time data, but for history, the Last 7 days view shows "No data is currently available" and the Last 31 days view will only show data from the earlier period where the history data was already stored.
The performance metric chart shows the earlier content and then skips to the current date.

Checking this data on the next day still only shows the current date.
The previous date is not shown any longer.
