Tools / Apache HertzBeat Interview Questions
What is the purpose of HertzBeat's agentless architecture?
The purpose is to remove the operational burden of installing, upgrading, and securing a monitoring agent on every single host, container, or device that needs to be watched.
Instead of an agent, HertzBeat connects directly to the target using a standard protocol it already exposes — HTTP for a web service, JMX for a JVM, SNMP for a network device, JDBC for a database — and pulls the metrics on a schedule.
This also removes the need to run a separate exporter process next to each service, which is a common source of extra maintenance in a Prometheus-based stack. Fewer moving parts per host means fewer things that can drift out of date or fail silently.
