Global Template Name: Agent G2 - Linux - Apache Pulsar Broker Monitoring
Introduction
The Apache Pulsar Broker actively monitors and keeps track of the performance metrics associated with different components of Apache Pulsar Broker. This includes components like Namespace, Topic, Lookup, Connection, and Jetty.
