[chef] What is this recipe 'monitor::redis'?

["A. Kong" < >]

Hi all,

I hope it is not a stupid question, but it is extremely hard to google the answer due to noise in search result

Here is the vagrant file: https://github.com/sensu/sensu-chef/blob/master/examples/Vagrantfile

In the file you will see these settings:

    chef.add_recipe "monitor::master"
    chef.add_recipe "monitor::redis"
    chef.add_recipe "monitor::rabbitmq"

I want to know 

1) Does ‘monitor::xxx’ has any special meaning here? Does it mean a redis recipe under a namespace ‘monitor’?

2) where are these recipes stored? I went to the getchef.com but there is not search functionality in the website. I visited https://github.com/opscode-cookbooks but it is not obvious to me which one is a recipe repository

Any pointer is appreciated

Cheers, Tony
