Description

Similar to the `top` command. It would ideally provide a list of sessions doing I/O, what kind of I/O, bandwidth of reads/writes, etc. Also the same information in aggregate form. The other metrics of general interest: caps outstanding, MDS cache size (broken down by type?), cache utilization/hits, client cache utilization (#26996), etc.
