Has anyone developed, or does anyone know of, any third-party tools (or non-obvious uses of the stock tools) to help a poor systems administrator determine what's going on with requests that are passing through Varnish? While
varnishhist give me either very high-level (or low-level) overviews, I'm looking for something that tells me things like:
- What requests are currently in progress (and how long they've been like that, where they got sent, that sort of thing)
- Average service times for requests by backend, vhost, that sort of thing
- Other things that will help me identify misbehaving backends, vhosts, etc.
