40.6 Working with Zone Platform Metrics

Virtualization Server platform metrics enable you to monitor the performance and resource usage of the virtualization server in your data center. You can use this information to balance resources or plan ahead to add resources to improve future performance.

The distribution of CPU and memory consumers is useful in managing the most heavily loaded zones, enabling you to be proactive in identifying potential issues. The last dashlet on the Summary page shows the date and time stamp for the last configuration change and the last incident.

The following zone metrics are available in the dashlets across the top of the page:

• Platform Status

  • Oracle Solaris version.

  • Current state: View the current health status and the time that the zone has been up and running.

  • Guest count. The guest count shows the total number of zones. If zones are still in the process of being discovered and promoted, the guest count will indicate the total number of guests and the number of guests that are still in the queue for auto promotion.

  • Open Incidents: View the number of Fatal, Critical, and Warning incidents. Click a number to view a synopsis. Click the synopsis to navigate to the Incident Manager console for incident details.

  • CPU Usage and Memory Usage: This section displays circular gauges showing the current platform CPU and memory as a percentage of the maximum values.

  • Up and Running Guests: This section displays the number of running zones out of the number of configured zones.

  • Virtual CPUs and Memory: This section displays pie charts showing the current number of allocated and available virtual CPUs and amount of allocated and available memory

  • Distribution of the CPU consumers per zone: View the total CPU consumption and the number of zones, or guests, that are consuming CPUs in the following ranges: 0-20, 20-40, 40-60, 60-80, and 80-100 percent.

  • Distribution of the Memory consumers per zone: View the total memory consumption and the number of zones, or guests, that are consuming memory in the following ranges: 0-20, 20-40, 40-60, 60-80, and 80-100 percent.

• Last changes

  • Configuration change: View the date and time stamp for the last change in configuration.

  • Incident: View the date and time stamp for the last incident.

The main body is made of 2 sections. The top one provides graphs showing the vCPU distribution per resource pool and zones, as well as the memory distribution per zones. The second section is the list of the guests. The Virtual Platform's Guests contains a list of the zones and zone details including the resources (vCPU, core, socket, share, memory) configured for the zone and those actually allocated to running zones. You can display the page as a list or a table. The default view is the List view, sorted by Incident count. The List view has sorting and filtering options that enable you to sort by incident and by allocated resources. Alternatively, you can view the Virtual Platform's Guests page as a sortable table. You can sort by the zone type, zone state, and by zone resource pool. You can also sort by the Fatal, Critical, or Warning incident columns.
