Description
Shows live performance statistics for all or specified volumes. For each volume these statistics
quantify I/O operations between hosts and the volume. For example, each time a host writes to a
volumes cache, the volumes statistics are adjusted. For volume performance statistics, the system
samples live data every 15 seconds.
Statistics shown only in API output are described in API basetype properties.
