Apache ActiveMQ Classic is a popular and powerful open source messaging and Integration Patterns server. It supports many Cross Language Clients and Protocols, comes with easy to use Enterprise Integration Patterns and many advanced features.
Now I want to add ActiveMQ Classic monitoring via the OpenTelemetry Collector which fetches metrics from jmx prometheus exporter run as a Java Agent.
There is no significant architecture-level change.
Apache ActiveMQ Classic has extensive support for JMX to allow you to monitor and control the behavior of the broker via the JMX MBeans.
Jmx prometheus exporter collects metrics data from ActiveMQ classic, this exporter is intended to be run as a Java Agent, exposing a HTTP server and serving metrics of the local JVM.
Using openTelemetry receiver to fetch these metrics to SkyWalking OAP server.
