Ability to see where SAM credentials are being used

Or at least see a number of how often it is used, similar as under Windows Credentials 'assigned to entities'.

The first credentials report can be of use, but displays all instances of all credentials - thousands of lines of data (my web browser eventually crashed the tab as there were too many results). Ideally UI should be able to show all instances just for the specific credential.

Yes, without this capability cleaning up credential store is a risky task. Collating several reports is not a simple solution.

These reports may be helpful but our environment is fairly large and very dynamic.  We currently have about 200 separate SAM credentials.  Even having a number next to the credential showing how many component monitors reference it would be nice.  That way we could delete any credentials with a zero next to it.

I believe the following reports may be what you're looking for.

• Credentials Used By APM Component Monitors
• Credentials Used By WMI Nodes‌
• AppInsight for SQL Credential Inheritance Report
• APM Component Monitors Whose Credentials are not Inherited from the Original Template
