LDoms Guest Status Test
This test enables administrators to determine how many guests have registered with the Oracle LDoms server, and how many of these are currently running. In addition, the test also indicates whether any guests have been newly moved to the target Oracle LDoms server or removed from it. The numbers of guests in various states of activity are also revealed by this test.
Target of the test : A Oracle LDoms server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for the Oracle LDoms server monitored.
| 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. By default, the port is NULL. |
|
KeonCommand |
Keon is a security mechanism that can be used with a multitude of operating systems to provide a centralized base for user account and password management, user access and inactivity control, system integrity checking, and auditing. If the Keon security model is in use on the Oracle LDoms host being monitored, then this test may require special user privileges for executing the operating system commands. In such a case, specify the exact command that the test is permitted to execute, in the KeonCommand text box. For example, if the keon command to be executed by the test is sudo, specify sudo in the KeonCommand text box. Alternatively, you can even specify the full path to the sudo command in the KeonCommand text box. On the other hand, if a Keon security model is not in place, then set the KeonCommand parameter to none. |

Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise 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:
|
| Measurement | Description | Measurement Unit | Interpretation |
|---|---|---|---|
|
Added guests |
Indicates the number of guests that were newly added to the Oracle LDoms server during this measurement period. |
Number |
The detailed diagnosis of these measures, if enabled, lists the guest domains that were either newly created on the Oracle LDoms server or moved from another server. |
|
Removed guests |
Indicates the number of guests that were newly removed from the Oracle LDoms server during this measurement period. |
Number |
|
|
Registered guests |
Indicates the total number of guest domains that have been registered with the server. |
Number |
|
|
Active guests |
Indicates the total number of guests that are currently running. |
Number |
|
|
Inactive_guests |
Indicates the number of guests that are currently inactive on the server. |
Number |
When a guest domain is stopped and resources mapped to it are released (i.e., unbound), the guest domain automatically switches to the inactive state. |
|
Guests in bind state |
Indicates the number of guests in the bind state. |
Number |
The LDom manager is responsible for mapping physical resources to logical domains. This resource mapping is referred to as ‘binding’. When physical resources are assigned (i.e., bound) to a guest domain, the domain is said to be in a “bind” state. |
|
Guests in unbind state |
Indicates the number of guests in the unbind state. |
Number |
If physical resources mapped (i.e., bound) to a logical domain are released, the domain switches to the unbind state. |
The detailed diagnosis of the Active guests and Inactive guests measures, if enabled, lists the virtual machines that are in an active or inactive state (as the case may be) on the Oracle LDoms server (see Figure 1).
