Within System Center Operations Manager 2012’s Web Console installation, the setup installs Application Advisor and Application Diagnostic – both, Application Performance Monitoring (APM a.k.a AVICode) components.
It’s all nice and good, but you may found yourself dealing with the below error while trying to access the Application Advisor and Application Diagnostic URLs:
“We apologize for any inconvenience caused by the temporary service outage” ? A quick look at the event viewer will show us the below Warning (not the full data from the event):
