This article describes how to use VisualVM to connect to a running instance of the eiPlatform in order to monitor its runtime CPU, heap, classes, and threads for profiling purposes.

Pre-requisites

• eiPlatform running as a Windows Service
• Java JDK version 8 or later
• VisualVM

Configure eiPlatform

Locate the “eiPlatform Service.vmoptions” file in the eiPlatform install directory and add the following lines:

-Dcom.sun.management.jmxremote

-Dcom.sun.management.jmxremote.port=9090

-Dcom.sun.management.jmxremote.local.only=false

-Dcom.sun.management.jmxremote.ssl=false

-Dcom.sun.management.jmxremote.authenticate=false

Start the eiPlatform service, or if it is already running restart to pickup the configuration changes.

Install and Configure VisualVM

Download VisualVM from https://visualvm.github.io/download.html and follow the directions to install it.

Start the VisualVM executable (visualvm.exe)

From the File menu, select “Add JMX Connection”

Set “Connection” to “localhost:9090”

Set “Display name” to “localhost-eiPlatform:9090”

Check “Do not require SSL connection”

Click OK

Double-click to open the “localhost-eiPlatform:9090” connection

Select the Monitor tab to view CPU, heap, classes and threads
