  Apache Tomcat is an open-source implementation of the Java Servlet, JavaServer Pages (JSP),
  Java Expression Language, and Java WebSocket technologies. It provides a pure Java HTTP web
  server and servlet container for hosting Java web applications. Tomcat exposes management APIs
  via the Manager application (HTTP text protocol), JMX for monitoring, and a Virtual Host Manager
  for configuration management. It is maintained by the Apache Software Foundation and is one of
  the most widely deployed Java application servers.

    name: Apache Tomcat Manager API
    description: >-
      The Tomcat Manager application provides an HTTP text protocol API for deploying, undeploying,
      starting, stopping, and reloading web applications remotely. Key endpoints include:
      /manager/text/list (list deployed apps), /manager/text/deploy (deploy a WAR file),
      /manager/text/undeploy, /manager/text/start, /manager/text/stop, /manager/text/reload,
      /manager/text/sessions (session statistics), and /manager/text/serverinfo. Requires
      manager-script role authentication.

    name: Apache Tomcat JMX API
    description: >-
      The Tomcat JMX API exposes management and monitoring beans for Connectors, Engines, Hosts,
      Contexts, Sessions, DataSources, thread pools, and memory via Java Management Extensions.
      JMX can be accessed via JConsole, Java VisualVM, or remote JMX clients. Prometheus JMX
      Exporter can expose Tomcat metrics in Prometheus format via HTTP endpoint.
