Question & Answer
Question
Is there a continuous Job Watcher function?
Answer
QMGTOOLS provides a program that allows for a continuous Job Watcher (JW) collection that collects and keeps a certain amount of collections.
Important notes: The MustGather Data Capture tool is provided as-is. It is created by IBM Support to help assist the user to capture data for debug. If you would like more information on using a JW monitor for your own purposes, see the following link.
Please install the required PTFs before collecting data:
