diskperf -y

In a server I monitor but don't have access, I'm not getting disk data. Dynatrace tells me:

Disk performance counters are disabled, use "DISKPERF -Y" command to enable them.

In the appmon days, a user stated that "For example in Windows Server 2012 R2 disk performance counters were disabled by default because of a noted significant performance impact in collecting Disk metrics on a Server ":

https://answers.dynatrace.com/questions/213935/view.html

In this case, it's a Windows Server 2019. Does someone know it it's disabled by default also, or if there is any indication for not running diskperf -y ?

Hey @Antonio S. I had a similar issue but with Network metrics. Turns out there was another performance monitoring tool that was taking the data and not allowing Dynatrace to capture the metrics. I's recommend checking that to ensure there isn't another performance/monitoring technology that might be preventing you from capturing the data as expected. Is this just on one host or all your hosts?

Great point. I'll be checking if that is the case.
