sstat

sstat [OPTIONS...]

sstat displays real-time status information for running Slurm jobs including CPU usage, memory consumption, and I/O statistics. It queries the jobacct_gather plugin for metrics on currently executing jobs and their steps.Root users can view all running jobs; regular users can only see their own jobs. The command is useful for monitoring resource usage during job execution and diagnosing performance issues.

Only works on running jobs; use sacct for completed jobs. Requires the jobacct_gather plugin. Available metrics depend on the specific plugin (linux, cgroup). Non-root users have limited visibility.

sstat is part of Slurm, developed at Lawrence Livermore National Laboratory starting in 2002. Job accounting features help users and administrators monitor resource consumption in real-time. Slurm is now maintained by SchedMD.
