This sample retrieves the performance statistics information using multi-threaded client program. It demonstrates using the best practices.

Usage:
java GetMultiPerfStats <host> <username> <password> <EntityName:EntityType[vm|host|rp|ccr]> <PerfGroup.PerfCounter.RollupType> [isCSVOutput]

################################################################################

Case 1:
Retrieved the past 1 hour samples (180 samples) for two entities.
One VM, and one Host. The VM is running on the specified Host.
All Perf stats are retrieved for each entity in one call, and for all entities
in one call. The times are recorded in both the cases.

Input:

Case 2:
Retrieved the past 1 hour samples (180 samples) for three entities.
One VM, and two Hosts. The VM is running on one of the specified Hosts.
