OVM – Compute Test

In the absence of adequate compute resources, the performance of the Oracle VM Server and its VMs will deteriorate. Administrators should therefore track how the server and its VMs use the available CPU resources, so that any potential contention for CPU resources can be proactively detected and resolved. This is where the OVM – Compute test helps. This test reports the physical CPU usage of the Oracle VM Server and points to that VM that is hogging the resources.

Target of the test : Oracle VM Manager

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the Oracle VM Server being monitored.

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed

Host

The host for which the test is to be configured.

Port

The port number at which the specified Host listens to. By default, this will be NULL.

Oracle VM Manager, Oracle VM Manager
User, Oracle VM Manager Password,
and Confirm Password

This test remotely connects to the Oracle VM Manager that manages the monitored Oracle VM Server and uses the web services API of the Oracle VM Manager to pull out metrics of interest. To enable this test to communicate with the web services API, you first need to configure the test with the IP address or host name of the Oracle VM Manager. This can be done using the Oracle VM Manager text box. Then, you need to configure the test with the credentials of a user with Admin rights to the Oracle VM Manager. Use the Oracle VM Manager User and Oracle VM Manager Password parameters to configure these credentials. Finally, confirm the password by retyping it in the Confirm Password text box.

SSL

By default, the Oracle VM Manager is SSL-enabled. Accordingly, the ssl flag is set to Yes by default. This indicates that the eG agent will communicate with the Oracle VM Manager via HTTPS by default.

WebPort

By default,, the Oracle VM Manager listens on 7002. This implies that while monitoring an Oracle VM server via an SSL-enabled Oracle VM Manager, the eG agent, by default, connects to port 7002 of the Oracle VM Manager to pull out metrics. In some environments however, this default port may not apply. In such a case, against the WebPort parameter, you can specify the exact port at which the Oracle VM Manager in your environment listens so that the eG agent communicates with that port.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Number of processors

Indicates the number of processors supported by the server.

Number

 

Cores per socket

Indicates the number of cores available per socket of the server.

Number

 

Processor speed

Indicates the speed at which the processors of the server have been configured to run.

Ghz

 

CPU utilization

Indicates the percentage of CPU resources used by the server and its VMs.

Percent

A very high value for this measure indicates excessive CPU utilization by the processors. The CPU utilization may be high because a few processes could be consuming a lot of CPU, or because there are too many processes contending for a limited resource. The detailed diagnosis of this measure, if enabled, lists the VMs and the physical CPU usage of each so that, the virtual machine that consumes the maximum CPU can be isolated.
