Historizing Performance Counter Data
The data that are written to performance counters can be written to Historian with the
Historian Performance Monitor Interface. There is a FULL version and a BASIC version of
this interface. The basic version has four limitations:
 It must run on the same machine as the Historian Server.
 It will collect data for a maximum of 512 points.
 Only one instance of the interface is allowed.
 Data can be collected for performance counters only on the local machine.
The full version does not have these limitations. For additional information, please see the
Historian Performance Monitor Interface Manual.
