Ravanello is the cli for analyze keys in redis and size of it's values. Example of usage: ```bash gem install ravanello ravanello --version REDIS_URL="redis://localhost/db" ravanello analyze --rules rules.yml ``` The rules files specifies the structure of the redis keys (splitted by :) and should looks like this: ```yml rules: resque: - 'delayed' - 'resque-retry' - 'timestamps' - 'lock' - 'meta' ``` After analyzing you will get the report in console: ``` Q-ty Size Key (sample) 4 24 * (hello) 1 6 denormalized:companies:* (denormalized:companies:99585213) ```
