varnish-top

varnish-top is inspired by memcache-top, which was in turn inspired by top.

Simply, it is a tool that lets you monitor a few key stats from one or more varnish boxes in real-time, from the command line, in a top-like screen. It's not the most sophisticated tool, but is handy for seeing a real-time view into how your box(es) are doing without needing to set up graphing, open up a browser, etc.

Similar to varnishstat, but runs across multiple boxes.
