dashboard for cloud servers

[trevj]

I want a dashboard for my cloud server. A few essential statistics;

• number of established peerconnections
• throughput (bytes being proxied/second)
• CPU load
• memory usage

This is for load testing and, eventually, end-users. I think this is higher priority even than a health checker because currently we don't even know how to check health.

I think there must be a bunch of open source tools we can use; we'll need to investigate those, and presumably add a bunch of instrumentation to the server itself.
