Is there a way to monitor jobs in SAM?
You would need to tie into something on the AS400...like the Help! Systems products such as robot console, robot, etc.
It would be better with a workload automation tool...
Yes, you can monitor your AS/400 using the Comtek AS/400 agent. An example template is available at the link below.
A free trial of the COMTEK /400 software is available here: COMTEK AS/400 OS/400 SNMP Agent Download Registration Form
It features a comprehensive product mib that is included in the SW mibs.cfg file as well as message monitoring, critical process monitoring and JobQ threshold monitoring.
Feel free to contact me if you need more specific details.
