in Windows 2008, how can I set up perfmon alerts to execute some scheduled task or batch file? I found examples for Windows 2003, but not 2008.
for example, I want to execute a task if free space on C drive goes below 10%. how would I do that?
Use the Reliability and Performance tool to monitor the "% Disk Free" counter. Create a Data Collector Set and set it to run the task when it falls below your threshold using the "Alert Task" tab in the Data Collector Properties.
