An instrumentation system for Ceph clusters.

Whiplash tells you things about the state of your Ceph cluster. It doesn't tell you anything that Ceph doesn't already tell you, but it does a lot more aggregating and filtering and massaging of data. There'll be more to say about this after there's some working code.

It also provides an out-of-band mechanism for ascertaining the state of a cluster, which can be invaluable when the cluster itself is under stress or is behaving anomalously.

Whiplash is written in Go, and so it is named after the family Mastigoteuthidae (Masti-go-teuth-idae), the whip-lash squid. You're welcome.
