The LDoms Guests Layer

The tests mapped to this layer auto-discover the guest domains configured on the Oracle LDoms server and report their status. The layer also reports the resource usage of each discovered guest in relation to the physical resources available to the Oracle host. Using the information reported by this test, administrators can:

  • Determine which of the guests is taking up more resources (CPU, memory, network, or disk) than the others. This information can help with load balancing or capacity planning. For example, if one of the guests is receiving a very high rate of requests compared to the others, this guest may be a candidate for migration to another server, so as to minimize the impact it has on the other guests on the current server.

  • Determine times when sudden or steady spikes in the physical resource utilization are caused by the guest machines
