| Name | Description | |
|---|---|---|
| PerformanceCounter(String, String, String) | Initializes a new instance of the PerformanceCounter class. | |
| PerformanceCounter(String, String, String, String) | Initializes a new instance of the PerformanceCounter class. | |
| PerformanceCounter(String, String, String, String, String) | Initializes a new instance of the PerformanceCounter class. | |
| PerformanceCounter(String, String, String, String, String, Single, Boolean) | Initializes a new instance of the PerformanceCounter class. |
| Name | Description | |
|---|---|---|
| AliasName | Gets or sets an alias name for the PerformanceCounter. | |
| AverageValue | Gets the average value from the samples of the BaseCounter. | |
| BaseCounter | Gets the PerformanceCounter object that this PerformanceCounter objects wraps. | |
| LastValue | Gets the last sample value from the samples of the BaseCounter. | |
| LifetimeAverageValue | Gets the average sample value over the entire lifetime of the BaseCounter. | |
| LifetimeMaximumValue | Gets the maximum sample value over the entire lifetime of the BaseCounter. | |
| LifetimeSampleCount | Gets the total values sampled over the entire lifetime of the BaseCounter. | |
| MaximumValue | Gets the maximum sample value from the samples of the BaseCounter. | |
| MinimumValue | Gets the minimum sample value from the samples of the BaseCounter. | |
| SampleAdjuster | Gets or sets an optional custom sample adjustment function. Can be used to apply linear adjustments to sampled values. | |
| SampleFilter | Gets or sets an optional custom sample filter function. Can be used to skip sampled values that are unreasonable. | |
| Samples | Gets a list of sampled values from the BaseCounter | |
| SamplingWindow | Gets or sets the number of samples to use to determine the LastValue, MinimumValue, MaximumValue and AverageValue. | |
| ValueDivisor | Gets or sets the divisor to be applied to the LastValue, MinimumValue, MaximumValue and AverageValue. | |
| ValueUnit | Gets or sets the measurement unit of LastValue, MinimumValue, MaximumValue and AverageValue |
| Name | Description | |
|---|---|---|
| Dispose | Releases all the resources used by the PerformanceCounter object. | |
| Dispose(Boolean) | Releases the unmanaged resources used by the PerformanceCounter object and optionally releases the managed resources. | |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) | |
| Finalize |
Releases the unmanaged resources before the PerformanceCounter object is reclaimed by GC.
(Overrides ObjectFinalize) | |
| GetHashCode | Serves as the default hash function. (Inherited from Object) | |
| GetType | Gets the Type of the current instance. (Inherited from Object) | |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) | |
| Reset | Resets the PerformanceCounter object to its initial state. | |
| Sample | Obtains a sample value from the BaseCounter. | |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
| Name | Description | |
|---|---|---|
| DefaultSamplingWindow | Default number of samples over which statistical values are to be calculated. | |
| DefaultValueDivisor | Default divisor to be applied to the statistical value. | |
| DefaultValueUnit | Default measurement unit of the statistical values. |
| Name | Description | |
|---|---|---|
| GetEnumValueOrDefault |
Gets the enumeration constant for value, if defined in the enumeration, or a default value.
(Defined by EnumExtensions) | |
| GetEnumValueOrDefaultT |
Gets the enumeration constant for this value, if defined in the enumeration, or a default value.
