n
If the Analytics service is running, select Admin > Support and examine the DT Calculation setting in
the DT Calculation Info panel.
Option Action
If DT Calculation: On
The dynamic threshold processing engine is running, but the queue might
be filling up because of contention when the DT processing engine tries to
read FSDB files. To reduce the number of DT threads and reduce the I/O load,
modify the DTProcessingThreads property in the
vcenter-
ops
\user\conf\analytics\advanced.properties file. The minimum
setting is 1.
If DT Calculation: Off
The dynamic threshold processing engine is not running, which might mean
that the drive system is not fast enough for the number of resources and
metrics being processed.
n
Use the FSDBHomeChanger tool to create additional mount points for
the FSDB so that files are distributed on multiple file systems.
n
Use the FSDBHomeChanger tool to move the FSDB to a larger or faster
drive.
n
Reduce the number of resources and metrics being collected to reduce
the demands on the drive.
Describe Failed
A describe failed for one of the adapters.
Problem
The message Describe Failed appears in the Reason pane of the Alert Summary page for the alert.
Cause
This problem can occur when you make changes to an adapter and try to update it. This alert is generated only
when the vCenter Operations Manager Web resource already exits. If the first describe for an adapter fails,
vCenter Operations Manager writes an error to the log file and sends a Describe failed email message.
Solution
1 Verify the changes to the adapter and try the update again.
2 If the update fails again, roll back the changes and revert to the older version of the adapter.
