Understanding the Nytro XD Solution : Performance Counters in Windows

Performance Counters in Windows

When Nytro XD is installed on Windows, the following counters appear under Nytro XD Caching Performance Counters in PerfMon or Performance Monitor. Performance Monitor displays the list of VDs that are added to the Nytro XD cache group, and for one or several VDs, you can select one or more than one counters.

Nytro XD exports the following performance counters to PerfMon available on any Windows server.
