Document what prerequisites are required

[spuder]

The documentation says that there are several prerequisites that are required.

Redis server and connectivity to a Redis database
RabbitMQ server, vhost, and credentials
Ruby JSON library or gem

It would be nice if there were a sentence explaining some of the following questions:

• Is there a way to setup those dependencies with other puppet modules?
• If so, is there a way to make sure that those modules are installed before sensu?

I'm guessing that I'll need to manually ssh into the machine and install those packages before installing sensu. (no way to simply provision a machine).

Happy to get a PR covering this. Thanks!

I have yet to get sensu installed with this puppet module. Do I need to manually install redis, and rabbitmq first? Does this module take care of that?

[jlambert121]

This module only manages sensu and the sensu config for sensu (including configuring sensu to talk to redis and rabbitmq). It does not install or configure those services directly. Looking at the forge (forge.puppetlabs.com), it appears the puppetlabs/rabbitmq is by far the most popular rabbitmq module. It doesn't look like there is a redis module that is significantly more popular than other ones.

Thanks, If I can get this going, I'll make pull request with some documentation examples incase anyone else runs into issues.

I have created a Vagrantfile which spins up ubuntu, installs uchiwa, redis, rabbitmq, adds users and then uses this puppet module to install sensu. I've also updated the Readme with some instructions.
