periods at the end of the name only, but they are not necessary. For example, the following are
permitted:

• com.foo.bar.
• mypackage.MyClass
Names such as *.util and com.*.util are not valid.

Viewing Monitoring Data in HPjmeter
Once you have started the data collection by opening a session in the console pane, you are ready
to view monitoring metrics.
• Click the time slice that you want to view. This will activate the Monitor menu selections.
• Click the Monitor heading to see the list of monitoring categories. Mouse over each category
to see the available metrics.
NOTE: A grayed-out menu item indicates that data is not currently available for viewing.
• Click the metric that you want to view.
The data for that metric will open in a separate, standalone visualizer that can be moved to
any location on your monitor screen.
• Use the visualizer buttons and other functions to manipulate the data in the visualizer.

Using Alerts
The console provides a way for you to enable and disable alerts for specific events when
monitoring an application. Enabled alerts can be deactivated and reactivated during the session
as needed by using the Alert Contr oller. In addition, you can set thresholds in the Alert Controller
to vary the sensitivity of the console to enabled alert conditions, and you can edit e-mail
notification attributes submitted when you set session preferences.
When active alerts are triggered, a notification appears in the main pane of the console window,
and the alert type and threshold value are displayed on all relevant metric visualizers. To view
details about the application behavior that triggered the notification, double-click on the specific
alert that you want to see. A metric window associated with the alert will open, with the alert
type and its threshold value displayed at the bottom of the window. For example, if you enabled
GC Duration (Major) and GC Duration (Minor) alerts, and the alerts were triggered, the GC
Duration visualizer might look something like this:
