The "pestat" tool can tell you the CPUload of nodes belonging to a job:

pestat -j jobid

Get pestat from
https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FOleHolmNielsen%2FSlurm_tools%2Ftree%2Fmaster%2Fpestat&data=01%7C01%7Ctwurgl%40goodyear.com%7C331258e9a6114731131c08d753f75e7b%7C939e896692854a9a9f040887efe8aae0%7C0&sdata=P%2BZUZsyZrjyGSQq52IzYZQL6g4JSJ8FAF1vnc8gHgQI%3D&reserved=0

The "psjob" tool prints the processes on nodes of a given job when
executed on the control node:

psjob jobid

get psjob and other tools from
