For the record, here's how to connect to a Redis server via Unix socket:

// CONFIG
$servers = array(
    array('Local', 'unix:///var/run/redis/redis-server.sock', -1),
);
// END CONFIG

Awesome script. I've made a few improvements and created a repo: https://github.com/tessus/redis-stats

Useful code, can I suggest my new project for monitoring Redis instances completely written in .NET with Razor Pages
