Like many companies, I’m sure, we’re investigating using Sensu for monitoring and Graphite for metrics collecting. The docs for making these two commuicate together over AMQP are pretty good except for one thing. Using the docs that I’ve read, when you start up Sensu first with its default options for AMQP, and then start up Graphite to read from that queue, Graphite will crash every time it tries to create the exchange.
