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:

  1. 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
     
  2. Show network statistics for the ldg5 and ldg6 domains every second five times.

    # ldm list-netstat -t 1 -c 5 ldg5 ldg6
     
  3. 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
     
  4. 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.
