I am experiencing the same issue. We have Splunk 7.1 on Linux and I am trying to monitor Windows infrastructure. I've deployed the Splunk app for Windows Infrastructure + all the related add-ons and when I go to "Settings" -> "Data Inputs" -> "Forwarded Inputs" -> "Windows Performance Monitoring" I am presented with a screen that says "Local Performance Monitoring". That is strange?!
Also, when I try to dig further down from there, e.g. I click on the "Processor" input I receive the above mentioned error message "Failed to fetch data: Admin handler 'win-perfmon-find-collection' not found." all over the screen.
Should I ignore this message, or there's an issue with my configuration? All the forwarders are installed on Windows desktops and servers with Local System account.
