Azure Diagnostic - how to get performance counter raw data

i am looking for a way to get the raw data from a performance counter in windows azure

using the diagnostic api.

so far I've noticed that i can configured a counter from the known counters

and set the sampling rate for that counter.

Is the sampling rate configured in the diagnostics con开发者_如何转开发figuration is the sampling rate

that the counter calculation is based on ?

if not how can i get the raw data for that counter, since i want to get the cpu user time (for example)

and do the calculation by myself.

thanks

Each counter has a sampling frequency from 1 second whatever number. Azure will sample each instance at the given rate and capture the values and store them inside each instance. Furthermore, there is a setting that allows Azure to transfer these values from each instance onto storage account's WADPerformanceCountersTable. The transfer setting is measured in minutes and a minimum of once per minute.
