VB.NET Core Classes in a Nutshell

Name

CounterSample

Synopsis

This structure contains a performance counter’s raw data. It represents a sample taken at a particular point in time (the CounterTimeStamp property). Calculate() returns a counter’s performance data as a float value. The two-argument form returns values for calculated performance counters, such as averages.

TimeStamp and TimeStamp100nSec return the system timestamp, with varying degrees of accuracy. (TimeStamp100nSec is the most precise, reporting a timestamp within .1 milliseconds.) BaseValue specifies a base raw value for samples based on multiple counters. RawValue contains the sample’s numeric value. SystemFrequency represents how often the system reads the counter, and CounterFrequency represents how often samples are taken by the counter. Both frequencies are represented in milliseconds.
