Hearsay is a library and a couple tools that turn your monitoring systems into sort of, broadcast radio stations for state and metric updates. Hearsay also provides what you need to listen to the broadcasts and automatically inject the monitoring events back into other monitoring systems or databases, or RRD's or whatever.The idea is to simplify inter-system communication between monitoring systems. As the list of insanely great monitoring systems grows, I've been limited by the configuration complexity of gluing them all together. I want to use the best tool for every job, eg Nagios for poll-based system state, Graphite for visualization, JMX-Trans for the Java guys, etc.. But every system I add forces me to reconfigure EVERYTHING.
