Have you tried viewing “Show Connected Alerts” within Microsoft Scom Operations Manager 2012 yet no alerts show? Perhaps older alerts persist?
Have no fear I may have an answer for you! Clear your cache 🙂
1. Close System Center Operations Manager
2. Run the following command from an elevated administrator command prompt:
“C:Program FilesSystem Center 2012Operations ManagerConsoleMicrosoft.EnterpriseManagement.Monitoring.Console.exe” /clearcache
3. The command above will automatically open System Center Operations Manager. It could take a few moments depending on your computers speed.
I hope this helps! 🙂
