RabbitMQ Key for monitoring specific queue

[galavichid]

Hi,

I have queue in our RabbitMQ cluster named 'Position'.
I would like to monitor its total queue messages number.
I have tried to add it by cloning one of the other triggers and changed it by suggestion from the internet, but no success.

rabbitmq.queue[<QueueName>,messages]

I still get an error when trying to collect the data.

Any suggestion?

Thanks
