Reporting Resource Usage in a Non-Global Zone
The zonestat utility reports on the CPU, memory, network, and resource control utilization of the currently running zones. For complete information about the utility, see the
zonestat(1) man page.
The zonestat network component shows the usage of virtual network (VNIC) resources on PHYS, AGGR, Etherstub, and SIMNET datalinks by zones. You can obtain information about other datalinks, such as bridges and tunnels, by using the networking utilities described in the
dladm(8) and
dlstat(8) man pages.
All zonestat options and resource types can also be invoked within a
non-global zone to display statistics for that zone.
root@zoneA:~# zonestat -z global -r physical-memory 2Note:
Non-global zone users ofzonestat are not aware of other zones using
system resources. When the zonestat utility is used in a non-global zone,
the combined resource usage of all other zones, including the global zone, is reported as
used by the global zone.
The following examples assume that you logged in to my-zone and are
assigned zone administration rights for my-zone:
Example 5-7 creates a report on several zones from the global zone. For more information about resource usage reports, see the
zonestat(1) man page.

Example 5-7 Displaying Exclusive-IP Zones' Network Bandwidth From the Global Zone
The following command shows the network bandwidth utilization for the system's exclusive-IP zones. It shows how much datalink bandwidth in the form of VNICs is in use and the per-zone utilization of each network device.
