public PerformanceCounterType CounterType { get; }
/** @property */
public PerformanceCounterType get_CounterType ()

public function get CounterType () : PerformanceCounterType

Property Value

A PerformanceCounterType that describes both how the counter interacts with a monitoring application and the nature of the values it contains (for example, calculated or uncalculated).

Exception typeCondition

InvalidOperationException

The instance is not correctly associated with a performance counter.

-or-

The InstanceLifetime property is set to Process when using global shared memory.

PlatformNotSupportedException

The platform is Windows 98 or Windows Millennium Edition (Me), which does not support performance counters.

The PerformanceCounterType enumeration contains the types of performance counters that you can interact with. Some of the counter types represent calculated values, such as the average of the counter measurements the system has taken. Other types represent raw, or uncalculated, values. The following table shows the counter types that you will interact with most frequently.

Counter's Responsibility

PerformanceCounterType Value

Example

Maintain a simple count of items or operations.

NumberOfItems32

Tracking the number of orders received as a 32-bit integer.

Maintain a higher-capacity simple count.

NumberOfItems64

Tracking the number of orders for a site with very high volume, stored as a 64-bit integer.

Track the number of items or operations per second.

RateOfCountsPerSecond32

Tracking orders received per second on a site.

Track a higher-capacity number of items or operations per second.

RateOfCountsPerSecond64

Tracking orders received per second on a site with very high volume.

Calculate the average time to perform a process or to process an item

AverageTimer32

Calculate the average time an order takes to be processed.

When you create a counter whose type requires the use of a corresponding base counter, you must declare the counter and the base in the CounterCreationDataCollection you pass into the PerformanceCounterCategory.Create method.

NoteNote

If the value for the InstanceLifetime property is Process and the performance counter category was created with .NET Framework version 1.0 or 1.1, an InvalidOperationException is thrown. Performance counter categories created with earlier versions use global shared memory, and the value for InstanceLifetime must be Global. If the category is not used by applications running on versions 1.0 or 1.1 of the .NET Framework, delete and recreate the category.
