I've noticed that the Exchange 2013 install created two data collector sets within Performance Monitor: ExchangeDiagnosticsDailyPerformanceLogExchangeDiagnosticsPerformanceLog These sets are creating daily log files saved in C:\Program Files\Microsoft\Exchange Server\V15\Logging\Diagnostics\DailyPerformanceLogs that are about 500MB in size, which are filling up our system volume. I've tried stopping them, but they get restarted automatically. I also tried deleting them, but they get recreated automatically. Is there a way to disable these? We have a 3rd party tool that we use for performance monitoring and would like to avoid having to delete these log files on a regular basis to keep our system volume from filling up. As a workaround, I've changed the path where the log files get saved to a non existent drive letter, but would still like to disable the Data Collector Sets completely. Thanks, -Cory

Where did you stop them? Within PerFmon or within the Task Scheduler? If you look under Windows\PLA in the Task Scheduler Manager, you can disable the actual running tasks there. See if that works.

Hi , Maybe you can modify registry to unload them. More information for your reference.

Andy- I was stopping them within PerfMon. I didn't know there were scheduled tasks for them. I disabled them in Task Scheduler and that seems to have worked. Thanks! -Cory
