CounterSample(Int64, Int64, Int64, Int64, Int64, Int64, PerformanceCounterType)

Source:

CounterSample.cs

Initializes a new instance of the CounterSample structure and sets the CounterTimeStamp property to 0 (zero).

public:
 CounterSample(long rawValue, long baseValue, long counterFrequency, long systemFrequency, long timeStamp, long timeStamp100nSec, System::Diagnostics::PerformanceCounterType counterType);

public CounterSample (long rawValue, long baseValue, long counterFrequency, long systemFrequency, long timeStamp, long timeStamp100nSec, System.Diagnostics.PerformanceCounterType counterType);

new System.Diagnostics.CounterSample : int64 * int64 * int64 * int64 * int64 * int64 * System.Diagnostics.PerformanceCounterType -> System.Diagnostics.CounterSample

Public Sub New (rawValue As Long, baseValue As Long, counterFrequency As Long, systemFrequency As Long, timeStamp As Long, timeStamp100nSec As Long, counterType As PerformanceCounterType)

Parameters

rawValue

Int64

The numeric value associated with the performance counter sample.

baseValue

Int64

An optional, base raw value for the counter, to use only if the sample is based on multiple counters.

counterFrequency

Int64

The frequency with which the counter is read.

systemFrequency

Int64

The frequency with which the system reads from the counter.

timeStamp

Int64

The raw time stamp.

timeStamp100nSec

Int64

The raw, high-fidelity time stamp.

counterType

PerformanceCounterType

A PerformanceCounterType object that indicates the type of the counter for which this sample is a snapshot.

Remarks

Use this constructor to take an initial sample of the performance counter. The System Monitor supplies values for these parameters automatically when you call the NextSample method for the first time.

Examples

The following example demonstrates how to initialize a new CounterSample structure, passing in values for the rawValue, baseValue, counterFrequency, systemFrequency, timeStamp, timeStamp100nSec, counterType, and counterTimeStamp parameters. After creating the CounterSample structure, the example displays the property values for the CounterSample in the console window.

Remarks

Use this constructor to take samples after you have already taken an initial sample of the performance counter. The System Monitor supplies values for these parameters automatically when you call the NextSample method.
