Disk Space - Console Test

This test auto-discovers the disk partitions supported by the control domain, and reports the space usage of each partition; this way, space-hungry partitions can be isolated.

This test is disabled by default. To enable the test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick Oracle VM Manager as the desired Component type, set Performance as the Test type, choose the test from the disabled tests list, and click on the < button to move the test to the ENABLED TESTS list. Finally, click the Update button.

Target of the test : Oracle VM Manager

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each disk partition of the control domain.

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.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total capacity

Indicates the total capacity of a disk partition; for the Total descriptor however, this measure indicates the total capacity across all disk partitions.

MB

 

Used space

Indicates the amount of space used in a disk partition; for the Total descriptor however, this measure indicates the sum of space used across all disk partitions of the control domain.

MB

Ideally, this value should be low.

Free space

Indicates the current free space available for each disk partition; for the Total descriptor however, this measure indicates the sum of free space available across all disk partitions.

MB

Ideally, this value should be high.

Percent usage

Indicates the percentage of space usage on each disk partition; for the Total descriptor however, this measure indicates the percentage of space utilized across all disk partitions.

Percent

A value close to 100% can indicate a potential problem situation where applications executing on the guest may not be able to write data to the disk partition(s) with very high usage.
