How to get current memory in use, no. of threads, CPU usage, load metrics etc. of a Java application that runs on Tomcat or Jetty. I need these metrics for finding the current state of the application if it's overloaded or underutilized etc. and I want to get this info from the application itself. Please guide.

topUnix-oriented operating systems (macOS, BSD, Linux, etc.) provide the command-line tool
topto view processes currently running. You can view your Java process’ use of memory and more.In macOS, the Apple app Activity Monitor provides this functionality in a GUI. See User Guide. Other platforms likely have a similar tool.
DTrace
DTrace is a technology for comprehensive dynamic tracing of both OS (kernel) and apps at runtime, with surprisingly little impact on performance.
Various operating systems incorporate this technology. In macOS, Apple wraps DTrace as their Instruments tooling. Some flavors of BSD also have DTrace built-in.
I believe DTrace can be used to monitor a running JVM, but I do not recall the details.
Debugger
Some IDEs are able to attach a debugger to your web app running in Tomcat or Jetty. Useful for development and testing, but not deployment.
Flight Recorder & Mission Control
Flight Recorder is a tool for profiling and event collection within a running JVM. See JEP 328: Flight Recorder.
Mission Control is a set of tools for detailed analysis of the extensive data collected by Flight Recorder. See wiki page. See this page by Oracle, but I’ve not checked to verify it is up-to-date.
Formerly commercial products from Oracle, both Flight Recorder and Mission Control are now housed at the OpenJDK project as open-source and free-of-cost projects.
JMX
You said:
Then JMX is for you.
Java Management Extensions (JMX) is a framework to export current runtime conditions information from within your app to external tools in a standards-based approach.
You can use your choice of a variety of monitoring tools to view the runtime info. This includes tools built on the Simple Network Management Protocol (SNMP) standard.
You can write your own JMX-compliant Managed Bean (MBeans) classes to report your own information. See tutorial by Oracle.
➥ Tomcat comes bundled with its own MBeans. See documentation, Monitoring and Managing Tomcat.
