Steps to Monitor Multiple Java applications running on a single server
Monitoring Multiple Java Applications on a Single Server
To monitor multiple Java applications running on a single server, the following steps can be followed:
APMInsight Java Agent 7.0 and above
Add the Java Agent Argument in Each Application Startup Script: (Recommended)
Follow the usual steps to configure the APMInsight Java agent -
- Add the below argument in the each application startup file
- -javaagent:"<agent_extracted_directory>/apminsight-javaagent.jar" -Dapminsight.application.name=<application_name> -Dapminsight.agent.server.port=<application_running_port>
Example : -javaagent:"D:\me\javaagent\apminsight-javaagent.jar" -Dapminsight.application.name="Ecommerce Application" -Dapminsight.agent.server.port=8080
Note : The above argument needs to be added to each application startup file with the corresponding application name and running port.
2. Restart your application Server to start monitoring your application
Add the Java Agent Argument in the Environment Variables of the Machine:
- Download the APMInsight Java agent and configure the host and license key of the Applications Manager Server - reference link
- Remove the default below key and values from the apminsight.conf file
- application.name=My Application
- agent.server.port=8080
- Add the below key and value in the apminsight.conf file
- auto.appname.enabled=true
- Configure the below key and value in the environment variables of the machine
- JAVA_TOOL_OPTIONS=-javaagent:"<agent_extracted_directory>/apminsight-javaagent.jar"
4. Start the Java application in a new terminal session.
Note : Adding the java agent argument on the environment level will add all the process created in the machine as a monitor in applications manager
APMInsight Java Agent 6.8 and below
- Add the below argument in the each application startup file
- -javaagent:"<agent_extracted_directory>/apminsight-javaagent.jar" -Dapminsight.application.name=<application_name> -Dapminsight.agent.server.port=<application_running_port> -Dapminsight.home=<home_directory_of _the_application> -Dapminsight.license.key=<your_apminsight_license_key> -Dapminsight.apm.host=<applications_manager_url>
Example : -javaagent:"D:/me/javaagent/apminsight-javaagent.jar" -Dapminsight.application.name='Ecommerce application' -Dapminsight.agent.server.port=8080 -Dapminsight.home="D:/me/myapplication" -Dapminsight.license.key=APMI_c6347e3652d5aae29d012a4a04f2f012572b183ae7b0845661dca95cb762c9d2 -Dapminsight.apm.host="htts://apm-prod-server:8443"
agent_extracted_directory - Directory where the agent is extracted
- application_name - Name of your application
- application_running_port - Running port of your application
- home_directory_of _the_application - Home directory of your application to store the agent related files.(Kindly provide a unique folder for each instance)
