Failed to find Premain-Class manifest attribute

Elastic Observability APM
1

Hi,
I am setting up with elastic java apm
And here are my configurations.

        ELK version 6.5.4
        APM Server version 6.5.4   
       apm-agent-attach-1.5.0.jar

When I try to run a java code I get the following error.

Failed to find Premain-Class manifest attribute in /home/abc/Desktop/apm-agent-attach-1.5.0.jar
Error occurred during initialization of VM
agent library failed to init: instrument

Kindly help.

It seems you are trying to install the agent using the -javaagent startup flag, while referring to the attach jar, instead of the elastic-apm-agent-<version>.jar.
Please read through our documentation regarding the different setup options.

I have downloaded the elastic-apm-agent-1.5.0
But while running a java code I am facing problem its giving the following error.

Failed to find Premain-Class manifest attribute in /home/abc/Desktop/apm-agent-attach-1.5.0.jar
Error occurred during initialization of VM
agent library failed to init: instrument

I made .war file of java code.
Can I run .war file from terminal.

You need a running Java app. If it is running on one of the supported app servers, follow setup instructions. Otherwise, go over installation options and manual tracing API to review your options.

Earlier it was working fine but now I am getting the error whenever I try to run apm server.

Could you set the log level on the server to debug to find more information about why publishing events fails.
