What does mean?

It is part of tracejob command:
momhop:2 serverhop:2 state:4 substate:42
What does mean momhom, serverhop, state, substate ?

Where I can find any information about those values?

Please check the PBS Pro reference guide for substate codes etc:

You can view all the manuals in one:

Thanks, I found codes for state and substate but I can’t find information about momhop and serverhop. What are those?
