As each Python agent runs a Python process, you can list which Python processes are being run, and where. For example the following command lists the Python processes per Python agent:
ps -ef | grep python
Where each process is being run is identified as follows:
<Desktop folder>.<workflow name>.<workflow instance name>.<agent name>
