Oracle VM Server for SPARC 3.6 features - improved network statistics visibility
Oracle VM Server for SPARC developer Lidong Chen contributed this post describing enhanced functionality.
ldm list-netstat command shows network statistics for multiple domains
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.
Requirements
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.
Usage
ldm list-netstat [-p] [-u R|K|M|G] [-t <interval>] [-c <count>][-o <net-device>] [<ldom>....]
Examples:
- Show network statistics for the primary and ldg5 domains every two seconds. Statistics are output every two seconds until you issue Ctrl-C..
# ldm list-netstat –t 2 primary ldg5
- Show network statistics for the ldg5 and ldg6 domains every second five times.
# ldm list-netstat -t 1 -c 5 ldg5 ldg6
- Show network statistics for net1 on the ldg5 and ldg6 domains every second 3 times.
# ldm list-netstat –t 1 –c 3 –o net1 ldg5 ldg6
- Show parseable network statistics for net1 on the primary and ldg6 domains every second 10 times.
# ldm list-netstat –p –t 1 –c 10 net1 primary ldg6
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
Summary
This new feature can be used to display virtual network activity for multiple domains, improving system visibility in Oracle VM Server for SPARC.
