vxstat is the Veritas Volume Manager (VxVM) management utility that allows you to print and reset statistics information on one or more volumes, plexes, subdisks, disks, or cache objects. It can also display statistics at specified intervals and for specified numbers of times. The vxstat utility reads statistics from the volume device files in the directory /dev/vx/rdsk and prints them to standard output. If you do not specify an object operand, vxstat reports statistics from all the volumes in the configuration database.The object can be the name of a volume, plex, subdisk, disk, or cache object. In a VxVM cluster environment, vxstat gathers the requested statistics from all the nodes in the cluster, and reports the aggregate totals. You can specify a node list to indicate a subset of nodes from which to gather statistics.
