Problem

After upgrading to 8.5.1 I cannot create QOS graphs in the custom dashboard when picking a QOS data source.  When I try to test the results using the dashboard portlet, I get this error:
Recipient[Actor[AKKA://dashboard/user/dao-router]]had already been terminated.

 

Environment

- UIM 8.5 upgraded to 8.5.1

Cause

dashboard portlet was in a bad state following upgrade to 8.5.1.

Resolution

To work around the problem, we did the following:

1. Open the wasp probe GUI using IM
2. Choose webapps Tab
3. Restart the dashboard portlet webapp

Data was then displayed in the dashboard when we returned to viewing it.

Test of the QOS also displayed QOS results as expected.
