Distributed Monitoring Solutionhttp://www.shinken-monitoring.org
Shinken is a new Monitoring Tool, allowing distributed monitoring.
Each component can run standalone on a dedicated machine and is independent
from the rest of the monitoring system. As result it's not a problem if
parts of the monitoring system hang or are down. As part of HA funtionality,
it's possible to configure a hot failover in a larger setup.
