If the Java Prometheus JMX (exporter) does not specify a port, it will by default scan all available ports—including DolphinScheduler’s Netty default port 1234—which leads to a protocol mismatch and results in “illegal packet [magic]”. Please check whether any similar monitoring services are scanning host ports. -- This is an automated message from the Apache Git Service.
