Foglight for JMX System Requirements Installing Foglight for JMX Managing JMX Agents Managing MBean Server Models Monitoring and Investigating JMX Data

Importing a Server Model

If another agent is monitoring the same or similar MBean types as an existing model, you can import a copy of the server model. The import process allows you to import a server model and edit its properties (for example, name and description).

To import a server model:
1
On the JMX view, click Import Server Model.
2
In the dialog box that opens, click Browse to locate your Server Model *.zip file.
3
After selecting the .zip file, click Inspect to confirm that the server model information was found.
4
Optional — Click Modify the id, name, and/or description of server model before importing. In the dialog box that opens, make the appropriate property changes, then click OK.
5
Click Import.
6
In the progress dialog box that opens, click OK.

Deleting Server Models

You can delete server models that you no longer need.

 
* 
NOTE: You cannot delete an MBean Server Model that is still in use.

If the selected server model is still in use by one or more agents, you must first remove the agent associations to the server model by doing one of the following:

•
Switching the MBean Server Model used by the associated agent(s).
For more information, see Switch a JMX Agent Server Model.
or
•
Deactivating and then deleting any agents associated with the MBean Server model.
For more information, see Activate and Deactivate JMX Agents.
To delete an MBean server model:
1
On the JMX view, click the name of the server model you want to delete.
2
In the list that opens, click Delete.
3
A warning message appears. Read the message and confirm the deletion by clicking Delete.
Otherwise, click Cancel to close the message box without deleting the server model.

Editing MBean Server Models

The MBean Server Model specifies which MBean types and which of their attributes to collect, as well as any derived metrics that should also be included. You can specify which instances to monitor for the server model, and override the model on an agent by agent basis.

After you have created a server model, you can edit it from the Server Model Editor dashboard.

To access the Server Model Editor dashboard:
•
On the Application Servers Administration dashboard, click the name of the agent whose server model you want to edit. In the list that opens, click Edit server model.
or
•
On the JMX Administration dashboard, click the name of the server model you want to edit. In the list that opens, click Edit.
In either case, the Server Model Editor dashboard opens in the display area.

The Server Model Editor dashboard lists the details of the available MBean types in the upper view, and the agents that are using the server model and their instance overrides (if any) in the lower view.

Click the name of an MBean type to access three options: Configure, Discontine as Roort Query, and Remove.

Configure

To configure an MBean type, follow the procedure in Adding a Root Type to an MBean Server Model , beginning from Step 6. Only the first step of the Adding a Root Type procedure is omitted; all other steps in these two procedures are the same.

Discontinue as Root Query

If you have an MBean type that is both a root query and is exposed through a relationship to another MBean type, you can stop using the MBean type as a root query. To do so, click the name of the MBean type and select Discontinue as Root Query. This option is only available for types that are both root queries and exposed through relationships.

 
* 
NOTE: MBean types that are only root queries (that is, they are not exposed through a relationship) can only be removed; they cannot be discontinued as root queries. For more information, see “Removing an MBean Type” on page 40.
Make Root Query

Alternatively, if you exposed an MBean type through a relationship, and now want to use it as a root query, you can do so.

To make an exposed MBean type a root query:
1
On the Server Model Editor dashboard, click the MBean type’s Name in the Configured MBean Types table.
2
In the list that opens, select Make Root Query.
Remove

To remove an MBean type entirely, see Removing an MBean Type .

Specifying Server Model Monitored Instances

You can specify the MBean instances to monitor by default at the server model level. These settings apply to all agents, unless you specify agent instance overrides, as described in Define Server Model Instance Overrides for a JMX Agent .

 
* 
NOTE: The server model must contain at least one Root Type before you can select instances to monitor. For more information, see Creating MBean Server Models.
To specify default instances for a server model:
1
On the Server Model Editor dashboard, click the text in the Monitored Instances column (for example, Do Not Monitor or All available) for an MBean Root Type.
2
In the Monitored Instances dialog box that opens, do one of the following:
•
To disable collection by default for the selected MBean type, select Do not monitor.
•
To monitor all instances that are available for the MBean type by default, select Monitor all available instances.
•
To specify which instances to monitor, select Monitor some available instances as follows, and then do one of the following:
•
Click Add Object Name Query to include or exclude instances that match the results of an object name query. On the Match Instances dialog box, type a query for the object name in the box, then click Set. Matching instances are included by default. To exclude them, clear the Include check box.
•
Click Add Regular Expression to include or exclude instances that match regular expression text. On the Match Instances dialog box, type the regular expression text in the box, then click Set. Instances with matching text are included by default. To exclude them, clear the Include check box.
3
Click OK.
The table updates to reflect any changes you have made to the monitored instances.
