How to monitor JVM with JRE only

Question

I have a Centos7 server and I want to monitor the JVM in order to identify performance issue but I have only JRE installed on the prod environment as follows:

Based on the research I saw there were some tool available such as Java Mission Control but it is only available with JDK but I have JRE installed. Any idea what open source tool I can use to monitor the jvm on centos with only JRE installed?

jattach gives you access to a few powerful tools, namely jcmd which you can then use to run various diagnostics commands against the java app. Works with plain JRE - check https://github.com/apangin/jattach
