In NetOps we have a Monitoring Profile that has numerous Metric Families in it. However when looking at it is blank. When editing it. It shows the Metric Families are selected. However when saving it we get the following error message 'An unknown error occurred while trying to save the monitoring profile. Please refer to the log files for more details.'
Dx NetOps Performance Management 20.2
There seemed to be some metrics that were no longer in the system They were showing up as the internal database name
Once removed, the monitoring profile saved fine
