Usage metrics

This is an overview of what the current resource utilization level of Puhti is.
Disk lag number is an indicator of how quickly the Lustre file system is responding at the moment. In certain situations, Lustre might slow down and seem very unresponsive, and then the IO lag will be high. Lower numbers are better.
