I use bluepill to track the health of service process (like a java web service for example). Bluepill outputs lines like: host service1 Going from starting => up host service1 Going from up => down host service1 Going from down => starting host service1 Going from up => unmonitored The set of states is small and finite. Some are 'good' states like: 'up' some are 'bad': unmonitored, down. What mechanisms are there to correlate and track this data? For example: 1. I would like to display a graph that tracks services by host that transition from up => unmonitored and back often. 2. I would like to alert when a given service transitions too quickly. 3. I would like to see if all services transition to a bad state at the same time. ... View more
