jmx_ prometheus_ Javaagent stopped running #669

Open ghost opened 2 years ago

ghost commented 2 years ago

Hi, I use JMX prometheus Javaagent monitors Tomcat and encounters a problem, JMX stops running! In http://prometheus_ip:9090/targets Down is displayed, but Tomcat can still be accessed normally.

I guess JMX quit because of the high load? How can I solve this problem?

Use the ss command to view the port status, there are a lot of close-wait. image

The first step would be to figure out why the jmx_exporter agent is unresponsive. Could you create a thread dump? This can be done by sending the -3 signal to the Tomcat process, like kill -3 <pid>.
