.NET Tip: It's 2:00 a.m. Do You Know What Your Processes Are Doing?

I recently needed to check on the status of some processes running on a server. I simply logged into the server and fired up Task Manager. This worked fine for a quick one-time check. What is really needed, though, is an automated way to keep tabs on these processes. The .NET Framework has classes that make it very easy to retrieve the same information that is available on the Processes tab in Task Manager. Here is a function that takes a process and returns its current state:

public enum ProcessState
   Responding,
   NotResponding,
      Unknown
}

public static ProcessState GetProcessState(Process Proc)
{
   if (Proc.MainWindowHandle == IntPtr.Zero)
      return ProcessState.Unknown;
   else if (Proc.Responding)
      return ProcessState.Responding;
   else
      return ProcessState.NotResponding;
}

The function above then can be used to determine the state of all processes running on the server. The following code loops through all processes running on the machine and displays their name and status.

ProcessState State;
foreach (Process Proc in Process.GetProcesses())
{
   State = Util2008.GetProcessState(Proc);
   Debug.Print("{0}: {1}", Proc.ProcessName, State.ToString());
}

Here is the output for the first few processes running on my computer.

OUTLOOK: Responding xplore: Responding
k9filter: Unknown
vpngvpngui: Unknown

You now have everything you need to automate monitoring the processes. Simply check that state of the process on a periodic basis and then take the appropriate action if the state is not what is expected.

  • Instead of only managing projects organizations do need to manage value! "Doing the right things" and "doing things right" are the essential ingredients for successful software and systems delivery. Unfortunately, with distributed delivery spanning multiple disciplines, geographies and time zones, many organizations struggle with teams working in silos, broken lines of communication, lack of collaboration, inadequate traceability, and poor project visibility. This often results in organizations "doing the …

  • With JRebel, developers get to see their code changes immediately, fine-tune their code with incremental changes, debug, explore and deploy their code with ease (both locally and remotely), and ultimately spend more time coding instead of waiting for the dreaded application redeploy to finish. Every time a developer tests a code change it takes minutes to build and deploy the application. JRebel keeps the app server running at all times, so testing is instantaneous and interactive.
