Performance Monitor may display some data incorrectly when you log data from multiple computers into the Perfmon log file. When you open the Perfmon log file in Performance Monitor and add the counters from all of the computers to view the data, Performance Monitor may show every ninety-ninth data sample for all the counters with zero data.

Performance Monitor always shows correct data for all of the counters from the computer whose data is logged first in the Perfmon log file.
