Request: simpleclient_tomcat - collector for Tomcat server

[devminded]

Purpose

Provide a collector for tomcat that can capture tomcat runtime metrics

Collector

• Uptime, tomcat version, build, etc
• thread pools/executors (name as label)
  • min
  • max
  • in use
  • idle
  • thread churn/creation rate
• connectors (name, port, protocol as labels)
  • min
  • max
  • queue depth (accept queue and in-progress requests)
  • timeouts
  • handle http/2 protocol and channels as well
• Sessions
• JDBC pools
• Access (realm, logins, blocked, jail, role, etc)

Integration

• Be able to use as a simple collector in existing web applications (nice when running a single app/tomcat in a Docker container)
• Be able to deploy as a war or java-agent (when running traditional war deployments in Tomcat application servers)
• Convince Tomcat maintainers to provide built-in support for Prometheus instead of JMXProxyServlet. ;)

There was a project I used some time ago (but now it is unmaintained) https://github.com/nlighten/tomcat_exporter Might be it still works (obviously only for Tomcat 9).
