Open Stack does not have a monitoring solution wired in. It is the resposibility of the implementer to architect a monitoring framework that verifies that the underpinnings of the Cloud are functioning properly.
Sensu was built to work with Configuration Management and provides a fast path to monitoring your Open Stack deployment.
It is a light weight but powerful alerting/metrics bus that is:
- Designed to work with elastic infrastructure.
- Easily customized
- built on top of modern services like RabbitMQ and Redis
