Unable to view temporal grouping or seasonal policy details

The policy details for temporal grouping and seasonal policies are not displayed in the GUI.

Problem

When you attempt to view the temporal grouping policy details in the GUI, the GUI displays the No group instances to display error. Similarly, when you attempt to view the seasonal policy details, the GUI displays the No historical data is available for this seasonal alert error.

Cause

The Events Query service does not connect correctly to the Cassandra database.

Resolution

To work around this issue, restart the eventsqueryservice pod, as in the following example:
oc delete pod $(oc get pods -n <noi-namepsace> |grep eventsqueryservice | awk '{ print $1 }')

Where <noi-namepsace> is the name of the namespace in which your Netcool® Operations Insight® deployment in installed.
