JVisualVM Plugin

Coherence installation includes a JVisualVM plug-in for monitoring Coherence cluster members in an aggregated view. The plug-in is located in the $COHERENCE_HOME/plugins/jvisualvm directory. Follow the steps below to install the plug-in.

1. Start jvisualvm.
2. Select the Tools/Plugins menu from the VisualVM console.
3. Select the Downloaded tab.
4. Select the Add Plugins... button.
5. Find and open the jvisualvm plugin from the dialog. It is located in the $COHERENCE_HOME/plugins/jvisualvm directory.
6. From the plugin list, select Coherence-JVisualVM and select the Install button.

Once the plugin has been installed, you can use the show_cluster -long command to display the JMX URL. By default, PadoGrid enables JMX on all members. You can copy any member's JMX URL and paste it to VisualVM when adding a remote connection.

show_cluster -long
