Oracle VM Server for SPARC developer Lidong Chen contributed this post describing enhanced functionality.
Oracle VM Server for SPARC 3.6 enhances the 'ldm list-netstat' command to show network statistics display for multiple guest domains. This enables you to view network statistics for specified guest domains in the system with a single command, which improves visibility of virtual network device activity.
To use this command, the guest domains must run at least Oracle Solaris 11.2 SRU1, and the control domain must run Oracle Solaris 11.4, now in public open beta.
ldm list-netstat [-p] [-u R|K|M|G] [-t <interval>] [-c <count>][-o <net-device>] [<ldom>....]
Examples:
An example showing network activity between two domains:
primary $ ldm list-netstat ldg1 ldg2
DOMAIN
ldg1
NAME IPACKETS RBYTES OPACKETS OBYTES
---- -------- ------ -------- ------
net0 280.06K 18.48M 1.06M 7.41G
------------------------------------------------------------------------------
DOMAIN
ldg2
NAME IPACKETS RBYTES OPACKETS OBYTES
---- -------- ------ -------- ------
net0 1.06M 7.39G 279.00K 18.41M
This new feature can be used to display virtual network activity for multiple domains, improving system visibility in Oracle VM Server for SPARC.
