Are you looking to monitor Disk Performance and have an Alert based on the threshold rate?
One option is to use the Exchange Server Monitor, but not use the Exchange specific counters.
Here is a list of system Counters you can use:
Disk Read Bytes per Second Disk Write Bytes per Second Pages per Second Page File Percentage Used Process Queue Length Context Switches Number of Processes
The other option is to use our External Monitor in conjunction with a WMI script. Let me know if this helps.
Thanks Derek. That is exactly what I am looking for.
