I want to read the (accumulated) pagefaults of a process from the windows shell to decide when to kill it. The process will start dynamically.

I found the killing part (e.g. here: How to monitor and kill a process automatically on windows by process name) but I found no way to read the page faults. I tried pfmon.exe from the windows resource kits (installed rktools.exe although it raised a incompatibility warning) with taskmgr and it works - I tried it with MathKernel (the process in question and after I added it to PATH) and pfmon says it is not supported.

I know of tasklist but this only shows me cpu time and memory usage.

Is there another way to read page faults? Can the taskmanager be used somehow automatically?


This is related to my post about a problem in Mathematica here for which I couldn't find a solution (I tried the 1 answer there). My script runs 8 parallel Mathematica Kernels for a computation which takes ~10 hours and sometimes one or two of them block. I already restart them for each computation but the behaviour prevails. At the moment I check regularly with the taskmanager on them and kill MathKernel.exe processes which accumulate a lot of page faults. Note that processor time/load and memory usage are not helpful while the other MathKernel.exe processes are still running. That's why I need the page faults - I want to compare all 8 processes say every minute and if one has 10 times the page faults of the other I want to kill it.


Is there another way to read this data?

You can use pslist from Windows Sysinternals:

Memory Abbreviation Key

All memory values are displayed in KB.

Pri: Priority
Thd: Number of Threads
Hnd: Number of Handles
VM: Virtual Memory
WS: Working Set
Priv: Private Virtual Memory
Priv Pk: Private Virtual Memory Peak
Faults: Page Faults
NonP: Non-Paged Pool
Page: Paged Pool
Cswtch: Context Switches

The faults value is the total number of page faults.

You will need the process IDs of the processes you want to monitor.

Example output:

> pslist -m 6272

You can use a batch file or PowerShell script to parse this output.

  • Thanks DavidPostill! I tried it and it does what I want. I will post my batch file in the other Question i linked. – Kab Jul 18 '17 at 12:33
  • I also don't need to use the PID. I can just use "pslist -m -nobanner MathKernel" and it will find all the processes. – Kab Jul 18 '17 at 13:53
  • @Kab Correct. My answer was just an illustration. You have to identify the processes somehow ... – DavidPostill Jul 18 '17 at 13:55
