Monitoring KVM instances with Sensu

Sensu is a complete monitoring solution that uses the client-server model; the server publishes checks in a message queue provided by the Rabbitmq service. The clients/agents subscribe to topics in the queue and execute the specified checks on the host they run on. State and historical data is stored in a Redis server.

In this recipe, we are going to install the Sensu server, Rabbitmq message queue, and the Redis server on one host, write a simple monitoring check using the information we obtained from the Resource usage collection with libvirt recipe earlier, and install the Sensu agent inside the KVM guest.
