How do I deploy multiple instances on a single host? - Application Real-Time Monitoring Service

To deploy multiple instances of an application on a single host, set the -Darms.agentId parameter to a unique value for each JVM process, such as 001, 002, or 003. This parameter specifies the JVM process to connect to.

Example

# Instance 1
java -javaagent:/{user.workspace}/ArmsAgent/aliyun-java-agent.jar \
  -Darms.licenseKey=<LicenseKey> \
  -Darms.appName=<AppName> \
  -Darms.agentId=001 \
  -jar demoApp.jar

# Instance 2
java -javaagent:/{user.workspace}/ArmsAgent/aliyun-java-agent.jar \
  -Darms.licenseKey=<LicenseKey> \
  -Darms.appName=<AppName> \
  -Darms.agentId=002 \
  -jar demoApp.jar

Replace the placeholders with your actual values:

Placeholder	Description	Example
`{user.workspace}`	Absolute path to the ARMS agent installation directory	`/home/admin`
`<LicenseKey>`	ARMS license key for your application	`LTAI5tXxx`
`<AppName>`	Application name registered in ARMS	`my-order-service`

Note

The -javaagent argument must appear before the -jar argument. It is a JVM option, not an application argument.

Note

For ARMS agent versions earlier than 2.7.3.5, replace aliyun-java-agent.jar with arms-bootstrap-1.7.0-SNAPSHOT.jar. Upgrade to the latest agent version to access current features and fixes.
