Microsoft COM+ Graph

This graph shows the resource usage of COM+ objects as a function of the elapsed load test scenario time.

X-axis

Elapsed time since the start of the run.

Y-axis

The resource usage of COM+ objects.

Breakdown Options

Each COM+ object is represented by a different colored line on the graph. The legend frame (which is found below the graph) identifies the objects by color:

Thread Event

Measurement Description

Thread Start

Rate at which single-threaded apartment (STA) thread for application have been started.

Thread Terminate

Rate at which single-threaded apartment (STA) thread for application have been terminated.

Work Enque

Event sent if a work is queued in single thread apartment object (STA). Note: These events are not signaled/sent in Windows Server 2003 and later.

Work Reject

Event sent if a work is rejected from single thread apartment object (STA). Note: These events are not signaled/sent in Windows Server 2003 and later.

Object Events

Measurement Description

Object Life Time

Duration of object existence (from instantiation to destruction).

Object Create

Rate at which new instances of this object are created.

Object Destroy

Rate at which instances of the object are destroyed.

Object Activate

Rate of retrieving instances of a new JIT-activated object.

Object Deactivation

Rate of freeing JIT-activated object via SetComplete or SetAbort.

Disable Commit

Rate of client calls to DisableCommit on a context. DisableCommit declares that the object's transactional updates are inconsistent and cannot be committed in their present state.

Enable Commit

Rate of client calls to EnableCommit on a context. EnableCommit declares that the current object's work is not necessarily finished, but that its transactional updates are consistent and could be committed in their present form.

Set Complete

Rate of client calls to SetComplete on a context. SetComplete declares that the transaction in which the object is executing can be committed, and that the object should be deactivated on returning from the currently executing method call.

Set Abort

Rate of client calls to SetAbort on a context. SetAbort declares that the transaction in which the object is executing must be aborted, and that the object should be deactivated on returning from the currently executing method call.

Method Events

Measurement Description

Method Duration

Average duration of method.

Method Frequency

Frequency of method invocation.

Method Failed

Frequency of failed methods (i.e. methods that return error HRESULT codes).

Method Exceptions

Frequency of exceptions thrown by selected method.
