2.15.4 Displaying the Statistics

Once the statistics have been pushed to the xenstore, you can view the statistics on dom0 and domU by running either of the following commands:

Note:

On domU's, ensure that the xenstoreprovider and ovmd packages are installed.

xenstoreprovider is the library which communicates with the ovmapi kernel infrastructure.

ovmd is a daemon that handles configuration and reconfiguration events and provides a mechanism to send/receive messages between the VM and the Oracle VM Manager.

The following command installs the necessary packages on Oracle Linux 5 and 6 to support the Oracle VM API.

# yum install ovmd xenstoreprovider

• The /usr/sbin/ovmd -g vmhost command displays the statistics on one line. The sed command breaks up the line into multiple lines, one statistic per line. You need to run this command as the root user.

  root@scac10db01vm04 ~]# /usr/sbin/ovmd -g vmhost |sed 's/; */;\n/g;s/:"/:"\n/g'
  com.sap.host.host.VirtualizationVendor=Oracle Corporation;
  com.sap.host.host.VirtProductInfo=Oracle VM 3;
  com.sap.host.host.PagedInMemory=0;
  com.sap.host.host.PagedOutMemory=0;
  com.sap.host.host.PageRates=0;
  com.sap.vm.vm.uuid=2b80522b-060d-47ee-8209-2ab65778eb7e;
  com.sap.host.host.HostName=scac10adm01.example.com;
  com.sap.host.host.HostSystemInfo=scac10adm01;
  com.sap.host.host.NumberOfPhysicalCPUs=24;
  com.sap.host.host.NumCPUs=4;
  ...
  

• The vm-dump-metrics command displays the metrics in XML format.

  [root@scac10db01vm04 ~]# ./vm-dump-metrics
  <metrics>
  <metric type='real64' context='host'>
  <name>TotalCPUTime</name>
  <value>242773.600000</value>
  </metric>
  <metric type='uint64' context='host'>
  <name>PagedOutMemory</name>
  <value>0</value>
  </metric>
  ...
  

  Note that you have copy the vm-dump-metrics command to the domU's from which you want to run the command.
