Profiling Monitor view

A project, complete with all the other resources required for profiling, is shown in the Profiling Monitor view whenever you launch either a local Java process or a remote one.

The Profiling Monitor view displays the profiling resources that get created during a profiling session. These resources are organized in a tree with the project being the root:

  1. Projects and folders project icon folder icon
  2. Monitors monitor icon
  3. Hosts host icon
  4. Processes process icon
  5. Agents (profiling and logging) agent terminated icon agent paused icon agent detached icon agent monitoring icon

    6.  

 
 

It is possible to keep profiling resources in any type of project or folder. Except for the project, the profiling objects are not directly related to a workbench resource.

Once you have profiled your application, you can open various Profiling and Logging views from any of the profiling resources in the Profiling Monitor view as indicated in the illustration. The hierarchical level of the resource in this view determines the type of information that is displayed in these views. For example, opening the Profiling and Logging views from the monitor rather than from an agent gives you a global, aggregated view of all the profiling data contained under this monitor. Views opened from the monitor level enable you to see the data from multiple hosts, processes and agents.

Whenever you launch or attach to a Java process, a logical representation of the Java process is created in the Profiling Monitor view. This representation, the process object, is identified both by name and an ID number (PID) that appears in the view along with the associated agents. The agents collect profiling data from your Java process, and this data can be analyzed.

The Profiling Monitor view is launched when you select the Profiling and Logging perspective.  Use this view to administer your profiling activity.

Controls

There are three groups of controls in the Profiling Monitor view:
  1. The menu to select objects
  2. The process controls
  3. The objects controls

Menu to select objects

Use this menu to select the objects that appear in the view.  Notice the objects appearing in the view, organized according to their position in the hierarchy.

 
 

Process controls

These frequently-used controls of the profiling process are available from near the top of the Profiling Monitor view.
start icon
Start monitoring a paused process
pause icon
Pause the monitoring of a process
garbage collection icon
Run garbage collection
collect object references icon
Collect object references (if available)
refresh icon
Refresh the Profiling Monitor view

Objects controls

These controls are obtained by selecting an object, right-clicking, then selecting the action. The choices of action available vary depending on what type of object is chosen (for example, only agents and processes can be terminated).

 
 

Attach to, or detach from, an agentmonitoring icon

See details about Launching or attaching a Java process.

  Reset Data monitoring icon

Select this action to set a new base line for the profiling data. After running this action, a new trace agent will be created under the existing process item and profiling data will be collected by this agent.

Run Garbage Collectionprocess icon

Determine the memory that the process is no longer using, and recycle it for other use.  This control is the same as:garbage collection icon

Collect Object Referencesprocess icon

If available, depict references to or from a set of objects. This is useful for locating objects that still have references to them, which might explain why garbage collection cannot occur for those objects.  This control is the same as:Collect object references icon

Launch or attach project icon folder icon monitor icon host icon

See details about Launching or attaching a Java process.

Terminate process icon

You can terminate a process that is either running locally on your machine or one that is running on a remote host.  Right click the process, then select Terminate.

The process is unconditionally terminated. There is no way to reverse this action. It is better to terminate the process in the way the Java program would normally expect it to be terminated, if such a way exists.

Relaunch process icon

After a process has terminated you can re-launch it with the same same conditions as previously. Right click the process, then select Relaunch. A process with a new ID and associated agents is created, and appears in the view.

Open With monitor icon host icon process icon

Open the selected object into the selected view.

Refresh Views monitor icon process icon

Refresh all views that are open.

Save project icon folder icon monitor icon host icon process icon

See details about Saving profiling resources.  To recover such saved resources, see Importing profiling resources.

Reload from Local project icon folder icon monitor icon host icon process icon

Load the saved information about the selected object, from the local file system. Use this to recreate the data collected during a previous profiling session.

Refresh project icon folder icon monitor icon host icon process icon

Refresh the Profiling Monitor view.

Delete project icon folder icon monitor icon host icon process icon

To delete a monitor, host, process object, or agent, right click it, then select Delete.  Select whether to delete from the view only or from the file system.  The selected item is deleted with all the objects below it in the hierarchy.

Properties project icon folder icon monitor icon host icon process icon

To view the properties of a specific monitor, host, process, or agent, right click it, then select Properties.  A preferences page appears.

A completed process, a terminated agent, and the associated monitor cannot be modified because there would be no point in doing so.   Otherwise, when you modify the information on this page, it takes effect the next time the associated package or host is used.

Many of the properties that you see here are also found in Windows > Preferences.  Whichever was the more recent property setting takes precedence.
