The following sections summarize how to use HPjmeter to monitor applications.
Detailed descriptions of the behavior of HPjmeter are linked to from each
section. Configure and Start Your Application | |
Set the command line of your Java application to use the JVM agent
and any desired agent options. Start your application with the JVM agent.
For details, see: Confirm that the Node Agent is Running | |
With a standard installation, the node agent should be running on the
systems where it was installed. For details about the node agent, see: Start the Console | |
Start the console from a local installation on your client workstation. For starting instructions by platform, see Starting the Console. Connect to the Node Agent from the Console | |
To connect to a node agent: Choose Connect from the File Menu
or click Connect to server [  ] In the Connect to Server dialog box, type the host name on which
a Java application and a corresponding node agent are running. If the node agent was started on a nonstandard port, specify a
port number in the Optional Port box. Click Connect. After a few moments, the running JVM for each application should appear
in the console main window pane marked with this symbol:  . Repeat the previous steps if you want to connect to several node
agents.
Set Session Preferences | |
Double-click on the JVM icon in the data pane for the application
that you want to monitor. This opens the Session Preferences dialog box. You can see the default settings for metrics, filters, and
alerts. Enable the settings that you want to activate. Click OK. The preferences window will
close and the newly Open Session will be visible, marked by this icon:  Wait for the console to collect metrics. The length of time depends
on the application size, the load imposed on the application, and on the selected
preferences. Typically, the wait will be from 5 to 30 minutes. Longer collection time gives you greater accuracy in the results.
For details, see: View Monitoring Metrics During Your Open Session | |
Click on the open session or time slice to highlight the data
that you would like to view. Use the Monitor menu on the console main
window to select the metrics that you want to see. Mousing over each category
in the cascading menu will reveal the relevant metrics for that category. Click a metric to open a metric visualizer displaying the
chosen data.
