Is there a tool to monitor synchronisation objects (mutex, events, semaphores) in Windows?

Question

In Windows, is there a tool to monitor the status of process synchronisation objects? ie.

• event/mutex : signaled or not signaled
• semaphore : count

Better yet, to log which thread did what, eg. "thread #5421 Signal Event - testevt"

Process Explorer

Handle usage: handle -s ==> Print count of each type of handle open.

[EDIT]:

How to monitor the status of process synchronization objects using Process Explorer.

Open Process Explorer

• Click on your exe in the process section (for ex: MyApp.exe)
• Click Show Lower Pane (or press Ctrl+L). This will show all synchronization objects. (for ex: myEvent)
• Right click on synchronization object (for ex: myEvent) and click Properties... in context menu.

• This brings the details of the synchronization object. In the Details tab, you can see

  Event Info (if synch object is event): Gives information about the state (whether the synchronization object is signaled)

  Semaphore info (if synch object is semaphore): Provides the count of the semaphore.
