The JVM Loaded Classes table in the Monitoring Configuration dialog box displays all classes and methods detected in the selected JVM in alphabetical order. To ensure that you are viewing the most updated list, check the “Last Updated” Last Updated date and time on the top right of the window, and if needed, click the refresh icon. If the “JVM JVM is stopped - last saved snapshot” text snapshot text appears, restart the JVM must be restarted in order to refresh the list.
The following table describes the information displayed in the “JVM JVM Loaded Classes” Classes table:
Table 1 Monitoring Configuration icons
| Column | Description |
|---|---|
| Class | Displays the loaded classes in the JVM. |
| Method | Displays the methods included in the class. |
| Status | Displays the monitored status of the selected entity. For more information, see “About Status values” on page 43 About Status values. |
| Type | Displays the type name of the selected entity. For more information, see “About Type values” on page 43 About Type values. |
| Remarks | Displays relevant remarks regarding the selected entity. JDBC methods will not appear in the loaded methods list. Methods invoking JDBC calls will appear with an indicator in the Notes column as “Calls Calls JDBC methods”methods. |
| Info |

| Name | Description |
|---|---|
| Monitored | For a class, it means that all of its loaded methods are instrumented. For a method, it means that the method is instrumented. |
| Monitored (partial) | For a class, it means that only some of its loaded methods are instrumented. For a method, it means that only some of the signatures are instrumented. |
| Excluded | For a class, it means that all of its loaded methods are ignored. For a method, it means that it is ignored. |
| Excluded (partial) | For a class, it means that all of its loaded methods are either ignored (exists at least once) or not instrumented (exists at least once). |
| <Blank> | For a class, it means that all of its loaded methods are not instrumented (but not ignored). For a method, it means that it is not instrumented (not ignored). |
| Pending | Relevant for classes or methods after a change was performed and the JVM was not restarted. The Class will have a pending status if it has at least one pending method. |

The type is used to categorize classes and methods as meaningful parts of the monitored application. Predefined types can contain HTTP, EJB and others. User defined types can be added when defining classes/methods to be monitored. (If no type is defined, the Custom default type is used.) The types are the foundation for displaying response time breakdown into its components in the Precise for J2EE User Interface (for example, how much time is spent in EJBs or in JDBC methods).
...
The type of classes can be defined by the user or by the product’s predefined definitions, or (when no specific definition exists) as a combination of all of its methods’ method types.
About modifying the Monitoring Configuration
...
At the top of the screen, the selected JVM name and its “Last Last JVM start time” Start Time (date and time) are displayed. The Monitoring Patterns table displays configured patterns (classes and methods, and their assigned types). Click Add Pattern (above the table) to create a new pattern name to the table.
...
The table (lower pane) displays the results (actual instrumentation status) for the selected classes or methods that match the selected definition row (upper pane).
The JVM “Loaded Loaded Classes and Methods” Methods displays (in parenthesis) the total number of classes that were loaded. Also displayed is the date and time when the classes were “Last updated”last updated.
Click the Refresh icon to refresh the screen and update all viewed data.

- Class (the class name)
- Method (the method name)
- Status (See “About Status values” on page 43 About Status values).
- Type (the assigned type Custom, “custom” by default)
- Notes (additional information for a specific class)
...
- On the Precise bar, go to Settings>Monitor Settings>Statistics Configuration (the link will only be active if the “Collect Statistics” check box is markedif Collect Statistics is checked). The Statistics Configuration dialog box will appear, displaying a partial list of all metrics detected in the selected JVM or cluster. The two lists, Available Metrics and Selected Metrics, respectively show which metrics have not yet been selected to appear in the Memory and Statistics workspace and which metrics have already been selected.
- Use the left and right arrows to move metrics between the two lists. By default, the Available Metrics list only displays a partial group of all detected metrics. To display all detected metrics, click Update Metrics. A message dialog box will appear. If you have made changes to the metrics, click Yes to save those changes before the metric retrieval process begins. Clicking No will begin the retrieval process without saving any changes made.
- To search for a specific group or metrics, enter a JVM property in the field below the Available Metrics heading and click Filter.
- Mark the “passwordRequired” check boxCheck Password Required.
- Click OK.
