sensu + riemann

sensu-riemann

* Sensu 
- As a nagios replacement basically, plus the extra goodies tha sensu has itself
(mutators, events filters , handlers, API, etc).

* Riemann
- When state tracking is needed, cause of the  powerful stream processing language,
I'm planning to aggregate events from client agents running on riak nodes, 
erlang queue size grow, cassandra, others, to track trends and report
on events, the idea is to report posible problems before they became critical.

* Graphite
- Of course fwd all the stuff to graphite :).
