I had a case where VMware monitoing stopped, with the entry "VMware invalid credentials handler" in the User column, when checking VMware Revision history. The Source is "Dynatrace server" instead of "Web UI".
It's not clear to me what this represents? Didn't receive any problem nor system notification. It disabled VMware monitoring, and once I reactivated the option, monitoring of VMware resumed.
Has anyone seen a case like this?
