SOI v4.0.2
From time to time I have noticed that one or more Data Sources are not displayed in the Event Policy GUI, when they have been there previously - I know this is only a graphical issue, as the Policies continue to be run. The MidTier Connector never disappears.
The only way I know to recover visibility of the missing Data Sources is to recycle the SOI components on the Manager, which is a little drastic!
I was wondering if anyone else has had this problem and whether there is a less intrusive way of recovering visibility.
