We have a database table that's a queue for jobs to process. I've added a SQL sensor to query the length of that queue, which returns me back an integer that I monitor and graph. Sometimes, the application that processes that queue crashes and we have to restart it. I'd like to build a notification that goes something like this....Notify me when the queue length has stayed the same for the past 10 minutes and the queue length is greater than 0. Is this possible?
