1. Navigate to <ServiceDesk_Home>\conf folder. Open wrapper.conf file in a text editor.
2. Add the java agent property to the conf file, under the key wrapper.java.additional.<argument_number>, as mentioned below. Ensure that the <argument_number> is unique, and doesn't exist already in the conf file.

wrapper.java.additional.50=-javaagent:"<agent_directory_full_path>/apminsight-javaagent.jar"

Note: Replace <agent_directory_full_path> with the full directory path where the APM Insight agent is installed.
