Remarks

This class returns information about ASP.NET worker processes that are running under the ASP.NET process model. Objects of this type are returned by the static methods ProcessModelInfo.GetCurrentProcessInfo and ProcessModelInfo.GetHistory. These methods are the only useful ways to create an initialized object.

Note

If you are using Microsoft Internet Information Services (IIS) 6.0, process metrics returned by the ProcessInfo classes are available only if you are running in IIS 5.0 isolation mode. If you are using IIS 6.0 in worker process isolation mode, the ASP.NET process model is disabled and an HttpException exception is thrown when you access ProcessInfo members.

Constructors

ProcessInfo()	Initializes a new instance of the ProcessInfo class.
ProcessInfo(DateTime, TimeSpan, Int32, Int32, ProcessStatus, ProcessShutdownReason, Int32)	Initializes a new instance of the ProcessInfo class and sets internal information indicating the status of the process.

Properties

Age	Gets the length of time the process has been running.
PeakMemoryUsed	Gets the maximum amount of memory the process has used.
ProcessID	Gets the ID number assigned to the process.
RequestCount	Gets the number of start requests for the process.
ShutdownReason	Gets a value that indicates why the process shut down.
StartTime	Gets the time at which the process started.
Status	Gets the current status of the process.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
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)
SetAll(DateTime, TimeSpan, Int32, Int32, ProcessStatus, ProcessShutdownReason, Int32)	Sets internal information indicating the status of the process.
ToString()	Returns a string that represents the current object. (Inherited from Object)
