Support Counting Messages on Subtopics #46

Open nevyen opened 2 years ago

nevyen commented 2 years ago

Hey,

for our project we have a very complex message on our topics. So they didn't contain any usefull information for monitoring.

But what I'd like to do is monitoring my subtopics.

For example I have a topic structure like /Version/+/Services/+

So I wan't to monitor when something was published on one of my services.

In my head this isn't to hard to implement.

  1. Subscribe to a topic
  2. Each subtopic which appears gets a value in the grahp
  3. Each time a new message arrives on the subtopic create point with timestamp

I tried to implemented myself. But I am very new to Grafana an Go. So any help would be nice.

First question is: How to get subtopic of a topic? As far as I can see a topic contains only an array of messages.
