［建议］希望加入Agent节点服务器信息收集功能

Indeed, this is a valuable suggestion. In Openjob, there are two different services: one is the openjob-server service based on spring-boot, and the other is a service dependent on openjob-worker-core. For the Java language, it could be a regular Java service or a service based on spring-boot. However, for Java, the most compatible method is using a javaagent.

For Java, I would recommend using the jmx_prometheus_javaagent. Taking Openjob's agent as an example, add the following to the pom.xml:

<dependency>
    <groupId>io.prometheus.jmx</groupId>
    <artifactId>jmx_prometheus_javaagent</artifactId>
    <version>0.16.1</version>
</dependency>

Then, by using the maven-assembly-plugin, a package with dependencies can be created and placed in the lib directory. At this point, you only need to write a startup.sh script for the project and add:

APP_HOME="$(cd `dirname $0`; pwd)"
JMX="-javaagent:$APP_HOME/lib/jmx_prometheus_javaagent-0.16.1.jar=9000:$APP_HOME/config/jmx/jmx_exporter_config.yaml"

Next, integrate the startup.sh script into the Dockerfile. This way, with zero costs for the user, the metrics collection problem is resolved.
