OVM Server Status Test

If a user complains that he/she is unable access a VM on an Oracle VM server, more often than not the reason for the inaccessibility is that the server has stopped running. To spot such abnormalities before a user complains, administrators can use the OVM Server Status test. This test tracks the status of the Oracle VM server and reports whether it is running or not. In addition, it indicates whether/not the server is in maintenance mode.

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

Server status

Indicates the current status of the Oracle VM server.

 

The values that this measure can report and their corresponding numeric values are discussed in the table below:

Measure Value Numeric Value
Stopped 0
Running 1
Starting 2
Not running 3

Note:

By default, this measure reports one of the values listed under Measure Values to indicate the current status of an Oracle VM server. In the graph of this measure however, the same is represented using the numeric equivalents only.

Is in maintenance mode?

Indicates whether/not the server is in maintenance mode.

 

An Oracle VM Server can be placed into maintenance mode to perform hardware or software maintenance. When an Oracle VM Server is placed in maintenance mode, any virtual machines running on the Oracle VM Server are automatically migrated to other Oracle VM Servers in the server pool, if they are available; otherwise they are stopped.

The values that this measure can report and their corresponding numeric values are discussed in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports one of the values listed under Measure Values to indicate whether/not the server is in maintenance mode. In the graph of this measure however, the same is represented using the numeric equivalents only.
