I'm trying to create capacity planner custom reports
and I'm looking for some assistance in finding more
information on the values required under the
different data sources. Specifically I looking for
some of the different perfmon (PerfClass,
PerfInstance or PerfMetric?) values.
I don't quite understand your question, are you looking for these values in order to create a custom report on the VMware CP dashboard or are you trying to collect this data outside of CP?
