Get tasklist.exe output

I can’t think of a way to get running tasks on the ignition gateway on windows. Can’t seem import psutil or get stdout from system.util.execute. Anybody got anything? I have a process that needs to be started if it is not running for some reason, and want to check first obviously.

Check out ProcessBuilder.

Check this

Hope this will help you out


That won’t work. psutil does not exist in Jython.

kwj, you will have to invoke a native task manager app and pull the results back using ProcessBuilder.

This is a script I made for an old project.
It checks if a specific process is running or not. ( in this case I put chrome.exe as an example )

[code]import subprocess

def processExists(processname):
command = ‘TASKLIST’, ‘/FI’, ‘imagename eq %s’ % processname
# shell=True hides the shell window, stdout to PIPE enables communicate() to get the tasklist command result
process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)
# trimming it to the actual lines with information
process_out = process.communicate()[0].strip().split(’\r\n’)
# if TASKLIST returns single line without processname: it’s not running
if len(process_out) > 1 and processname in process_out[-1]:
print(‘process “%s” is running!’ % processname)
return True
print(‘process “%s” is NOT running!’ % processname)
return False

processExists(‘chrome.exe’) [/code]


This is perfect. Thank you very much.
