No main manifest attribute, in jmx_prometheus_javaagent-0.16.1.jar

When following the README command,

java -javaagent:./jmx_prometheus_javaagent-0.16.1.jar=8080:config.yaml -jar jmx_prometheus_javaagent-0.16.1.jar

I get the following error: no main manifest attribute, in jmx_prometheus_javaagent-0.16.1.jar

In The MANIFEST.MF and pom.xml file, I do not see a Main-Class but only an Agent-Class and a Premain-Class. Is this intended? What is the correct way to run this?

The last argument should be the JAR file of your application that you want to monitor, like

java -javaagent:./jmx_prometheus_javaagent-0.16.1.jar=8080:config.yaml -jar yourJar.jar

The last argument should be the JAR file of your application that you want to monitor, like

java -javaagent:./jmx_prometheus_javaagent-0.16.1.jar=8080:config.yaml -jar yourJar.jar

Even if we provide the jar we want to monitor, it gives same error

[fstab]

Could you try to run the same command without the -javaagent:./jmx_prometheus_javaagent-0.16.1.jar=8080:config.yaml parameter? I assume that the Main-Class attribute is missing in your application JAR, and that's causing the error.

I tried that and it didn't work. Have another suggestion?

Please provide the full/exact command line you are using.

Hi, I am also getting the error after running : java -javaagent:./jmx_prometheus_javaagent-0.19.0.jar=12345:kafka-0-8-2.yml -jar jmx_prometheus_javaagent-0.19.0.jar

no main manifest attribute, in jmx_prometheus_javaagent-0.19.0.jar

please help to fix the same or any other command which will work

@BIPINAIREE this is working as expected. The JMX Exporter Java agent jar is a Java agent that you configure to run with your application.

Example:

java -javaagent:./jmx_prometheus_javaagent-0.16.1.jar=8080:config.yaml -jar yourJar.jar
