Nsclient++: Solving various PDH value errors

Problem:

Errors like these:

ERROR: Could not get data for 5 perhaps we don’t collect data this far back?

ERROR: Failed to get PDH value

PdhAddCounter failed: The specified object was not found on the computer.   (C0000BB8)

 

Solution:

Many errors regarding Perflib / performance counters can be solved with these commands (run them via cmd):

lodctr /R

lodctr /e:PerfOS

Then restart Nsclient++ service.
