[slurm-users] monitoring and update regime for Power Saving nodes

[Brian Andrus]

David,

For monitoring, I use a combination of netdata+prometheus. Data is 
gathered whenever the nodes are up and stored for history. Yes, when the 
nodes are powered down, there are empty gaps, but that is interpreted as 
the node is powered down.

For the config, I have no access to DNS for configless so I use a 
symlink to the slurm.conf file a shared filesystem. This works great. 
Anytime there are changes, a simple 'scontrol reconfigure' brings all 
running nodes up to speed and any down nodes will automatically read the 
latest.
