Question on best way to handle availability issue with eventhub

[kwontae]

So I have a quick question.

My team is working on a scheduler component which basically goes through the payload intake and distribute the load across all event hubs determined by the region (Payload will have an array of items that have a region as a field).
I want to be able to say if sending the batch of events have failed due to resource being down or bad name, I want to send it a different one (round robin for the sake of POC). I thought about using the azure resource health api, but I want to minimize the REST calls as much as possible as it's quite expensive. I've written a test with a random namespace that doesn't exist and instead of returning an exception/error, it panicked and exited my program. Is it possible to have a graceful method for this so I can have a handler that will apply round robin algorithm if there was an exception/error from .SendBatch()?
