Hello,
We have a Service Bus topic that has multiple subscriptions and all of them are forwarding messages to other topics based on some rules.
What metrics are worth monitoring (creating alerts for) on this topic? Is it worth looking at Count of dead-lettered messages in a Queue/Topic, or Server Errors, or User Errors? What are the possible errors that could occur on a topic / subscription that all it does is to forward messages?
Thank you,
Cosmin
