Not specifically Slurm, but it can be useful to have alerts on jobs which
either will never start or which are 'stalled'.
You might want to have an alert on jobs which (say) request more slots or
nodes than physicall exist, so the users job will never run.
Or you can look for 'stalled' jobs where the CPU time used never increases.
