Almost all performance monitoring tools can monitor 16-bit applications on Windows NT 4.0 Server and Workstation. However, because they run in the same process, the trick to monitoring more than one 16-bit application is to distinguish among the threads of the NTVDM process.
To monitor one 16-bit application, simply select the NTVDM process in Performance Monitor, Task Manager, Process Explode, Process Viewer, Process Monitor, or another tool. If you have multiple 16-bit processes running in NTVDM, you can distinguish them by their thread IDs in all tools except Process Monitor.
