I think we don't have a showcase about PULSAR, if you have tested it, could you add some relevant screenshots？

@CodePrometheus Please follow the above review and resolve the conflicting.

Sorry, I've been busy with work lately. The showcase is in progress, and local test is as shown below, but the service_hierarchy_relation does not seem to be related to Virtual-MQ and Pulsar-cluster now, I'm still trying to figure it out, If teachers have any suggestions please let me know, thanks very much.

From what I saw, your V-MQ is using IP:port which is provided by the agent plugin, meanwhile, server monitoring is using service name in k8s or something similar. You build the hierarchy rules, you need to make sure whey are aligned and the rules follow the setup.

Due to the difficulty of building the IP:port format relationship with the Pulsar-cluster ,I suggest adjusting local hosts to accommodate the Pulsar-cluster name If Pulsar java plugin report the address name as I suppose

It works, @peachisai You’re a genius! Very thanks~

And I have an idea, is it possible to declare an empty custom key in auto-matching-rules, such as custom: ""
