Introducing Vector: Netflix's On-Host Performance Monitoring Tool
It gives pinpoint real-time performance metric visibility to engineers working on specific hosts -- basically sending back system-level performance data to their browser, where a client-side renderer turns it into a usable dashboard. Essentially the idea is to replace having to ssh onto instances, run "top", systat, iostat, and so on.
