Monasca is a powerful tool in the OpenStack arsenal. It brings metrics and alarms to the operator. It even pairs grafana with horizon. It currently monitors Swift, but just the processes. But there is so much more we can grab. Swift actually generates heaps of metrics. For one It has supported sending metrics via statsd for years. All the internal daemons send statsd. Further, built into each server is a reconnaissance API (recon), that you can hit over REST or by using the swift-recon tool. Swift operators have been using these for years.
