Vista Reliability Monitor no longer adding new dataPosted: September 24, 2007
A new feature in Vista is the Reliability Monitor. It compiles data from the event log, Windows errors, blue screens, and various Windows performance logs to compute a reliability index from 1 to 10 (where 10 is most reliable). More importantly, it graphs the index over time and can give you a quick snapshot of any problems with the machine.
I had a problem with the Reliability Monitor not updating its data since early August. I found this solution on the microsoft.public.windows.vista.performance_maintenance newsgroup and am promoting it here. Hat tip to clayga.

- Open a Command Prompt with elevated (Administrator) privileges.
- Execute RACAgent at the prompt. Note that the task will run for a while
(several minutes on my system).
- Open Reliability Monitor. Note that some or all of the Stability Chart
- Check the "Last Updated:" date. If it’s earlier than yesterday’s date,
repeat steps 4 and 5 after first closing Reliability Monitor.
