Steps to Monitor Multiple Java applications running on a single server
Monitoring Multiple Java Applications on a Single Server:
Refer this document to find your java agent version
Note: Ensure that agent's -D and -javaagent argument values — including the agent directory path and application name — should not be enclosed in double quotes.
APMInsight Java Agent 7.0 and Above
Approach 1: Add the Java Agent Argument in Each Application Startup Script (Recommended)
1. Download and extract the APMInsight Java agent and configure the host and license key of the Applications Manager Server (refer to the documentation for details) and add the following argument to each Java application startup file:
-javaagent:<agent_extracted_directory>/apminsight-javaagent.jar -Dapminsight.application.name=<application_name> -Dapminsight.agent.server.port=<application_running_port>
Example:
For windows,
-javaagent:D:\me\apminsight-javaagent\apminsight-javaagent.jar -Dapminsight.application.name=Ecommerce Application -Dapminsight.agent.server.port=8185
For Linux,
-javaagent:/opt/apminsight-javaagent/apminsight-javaagent.jar -Dapminsight.application.name=Ecommerce Application -Dapminsight.agent.server.port=8185
Note: The above argument must be added to each application's startup file with the corresponding application name and running port.
2. Restart your application server to start monitoring your application.
Approach 2: Add the Java Agent Argument in the Environment Variables of the Machine
Note: Adding the Java agent argument at the environment level will include all Java processes created on the machine as monitors in the Applications Manager.
1. Download the APMInsight Java agent and configure the host and license key of the Applications Manager Server (refer to the documentation for details).
2. Remove the default key and values from the apminsight.conf file:
application.name=My Application
agent.server.port=8080
3. Add the following key and value in the apminsight.conf file:
auto.appname.enabled=true
4. Configure the following key and value in the environment variables of the machine:
JAVA_TOOL_OPTIONS=-javaagent:<agent_extracted_directory>/apminsight-javaagent.jar
Example:
For windows,
JAVA_TOOL_OPTIONS=-javaagent:D:\me\apminsight-javaagent\apminsight-javaagent.jar
For Linux,
JAVA_TOOL_OPTIONS=-javaagent:/opt/apminsight-javaagent/apminsight-javaagent.jar
5. Start the Java application in a new terminal session.
APMInsight Java Agent 6.8 and Below
1. Download and extract the APMInsight Java agent. Delete the apminsight.conf file present in the extracted directory. Then, add the following argument to each application's startup file:
-javaagent:<agent_extracted_directory>/apminsight-javaagent.jar -Dapminsight.application.name=<application_name> -Dapminsight.agent.server.port=<application_running_port> -Dapminsight.home=<agent_extracted_directory>/<application_name> -Dapminsight.license.key=<your_apminsight_license_key> -Dapminsight.apm.host=<applications_manager_url>
2. Restart your application server to start monitoring your application.
Example:
-javaagent:D:/me/apminsight-javaagent/apminsight-javaagent.jar -Dapminsight.application.name=Ecommerce application -Dapminsight.agent.server.port=8185 -Dapminsight.home=D:/me/apminsight-javaagent/Ecommerce application -Dapminsight.license.key=APMI_c6347e3652d5aae29d012a4a04f2f012572b183ae7b0845661dca95cb762c9d2 -Dapminsight.apm.host=https://apm-prod-server:8443
Key Definitions:
- agent_extracted_directory: Directory where the agent is extracted.
- application_name: Name of your application.
- application_running_port: Running port of your application.
- your_apminsight_license_key: License key of the Applications Manager Server.
- applications_manager_url: Applications Manager Server URL.
