rascal doesn't provide any information as if its connected correctly or not to rabbitmq

Just a general question that i can't find any doc on that!
When creating a broker, how come if I don't have any rabbitmq cluster running and the conf is pointing to whatever, i don't get any error from rascal !?!?
I don't have a snippet unfortunately but my point is, i am creating a broker and i publish a message. I will receive an error telling me that something went wrong with the publication. But how come rascal is not verbose at all about its "failing" connection at first ?
Is there any way to "healthcheck" the rabbitmq connection with rascal ?
Hi @manodupont,
Pretty hard to tell without a code snippet, but I suspect you're picking up Rascal's defaults which attempt to connect to localhost on port 5672. Maybe you have RabbitMQ running locally? Maybe you aren't waiting long enough for an connection timeout error?
If you post some sample code I'll take a look. Alternatively if you set the DEBUG environment variable to rascal:* you'll see exactly what Rascal is attempting to connect to under the hood and whether it is successful.
Well, i am still looking to narrow it down. If i take the whole example from the main page on the repo. i do get an EADDRNOTFOUND straight away when trying to connect to this broker.example.com broker.
I think it's just that there are 0 vhosts, so Rascal isn't attempting to connect to anything. Agree that's not a legit scenario and happy to add some validation to yield an error if there aren't at least 1.
I think this makes sense. Ill check on that ...
