[lustre-discuss] Command line tool to monitor Lustre I/O ?

[Christopher Johnston]

I use the exact same setup along with Kapacitor for alerting (alerta as the
dash).  We have created have dozens of panels in Grafana that are very
useful for troubleshooting bottlenecks with the OSS nodes, disks, as well
as the clients.

Can't go wrong with it I feel, easy to setup and fun to make graphs :-)
