To obtain information from a counter, you might need to convert the raw data generated by the counter into data that is more easily interpreted.

Remote Performance Monitor supports the following PERF types as counters, including calculations that can be used to convert raw data:

CounterDescription
PERF_100NSEC_MULTI_TIMERPerforms timer sampling of multiple but similar items on a 100Nsec interval.
PERF_100NSEC_MULTI_TIMER_INVCalculates the inverse of the timer for multiple but similar items on a 100Nsec interval.
PERF_100NSEC_TIMERPerforms timer sampling of a single object on a 100Nsec interval.
PERF_100NSEC_TIMER_INVCalculates the inverse of the timer for single objects on a 100Nsec interval.
PERF_AVERAGE_BULKGives the bytes per operation when divided by the number of operations.
PERF_AVERAGE_TIMERGives time per operation when divided by the number of operations.
PERF_COUNTER_BULK_COUNTShows the byte transmission rates.
PERF_COUNTER_COUNTERTracks the rate of counts.
PERF_COUNTER_LARGE_RAWCOUNTGives instantaneous counter values for large values.
PERF_COUNTER_LARGE_RAWCOUNT_HEXGives instantaneous counter values in hexadecimal values for large values.
PERF_COUNTER_MULTI_TIMERPerforms timer sampling of multiple but similar items on a specified interval.
PERF_COUNTER_MULTI_TIMER_INVCalculates the inverse of the timer for multiple but similar items on a specified interval.
PERF_COUNTER_QUEUELEN_TYPECalculates the inverse of the timer for multiple but similar items using (X1-X0)/(Y1-Y0).
PERF_COUNTER_RAWCOUNTGives instantaneous counter values for specified values.
PERF_COUNTER_RAWCOUNT_HEXGives instantaneous counter values in hexadecimal values for specified values.
PERF_COUNTER_TIMERPerforms timer sampling of a single object on a specified interval.
PERF_COUNTER_TIMER_INVCalculates the inverse of the timer for single objects on a specified interval.
PERF_ELAPSED_TIMESubtracts the start time of the item being measured, from the snapshot time to yield the elapsed time.
PERF_RAW_FRACTIONCalculates the instantaneous value, divided by the base data.
PERF_SAMPLE_COUNTERProvides a count that is either 1 or 0 for each sampling interrupt.
PERF_SAMPLE_FRACTIONCalculates a percentage value of the number of samples with value 1, when each sampling interrupt is either 1 or 0.
