There is a graphing tool that uses elements directly from sacct to display information about the current cluster usage, node_usage_graph (located at in the anunna module ).
Example:
[user@login0 ~]# module load anunna
[user@login0 ~]# usage_graph
node: |0% 100%|

This gives an overview of the current per-node resource usage. There are four types of letter:
- M: Memory reserved and in use
- m: Memory reserved and not in use
- C: CPU reserved and in use
- c: CPU reserved and not in use
- D: Drained node (not available for submission for some adminstrative reason
- R: Reserved node
It cannot however give you an indication of how much the queue is right now for any node. for that, squeue is a better resource.
