Sensu Experiment

This is me doing a crazy sensu experiment to understand it better. To play along, you will need the following:

• Boot2Docker
• Docker Compose
• Virtualenv or virtualenvwrapper
• A decent internet speed (the initial pull of docker containers can be EXPENSIVE)

Getting Started

Once you have the above installed you're ready to start hacking.

• clone this repo

• docker-compose up -d - bring up all the pieces: rabbitmq, redis, sensu+uchiwa, rabbitmqagent

• navigate to http://192.168.59.103:3000/ to access the uchiwa dashboard. The login is admin/secret

• navigate to http://192.168.59.103:15672/ to access the rabbitmq management console. The login is guest/guest.

That's it! That's the main pieces we'll be interested in.

Strucure

Configs used within containers:

• etc/sensu - configuration for sensu-server and uchiwa
• etc/rabbit - configuration for rabbitmq
• etc/rabbit-agent - configuration for the rabbitmq agent

For container building:

• rabbit-agent - builds the rabbit agent container
• sensu - used to build the sensu-server container

Adding a New Check

Basically, just drop the plugin under etc/rabbit-agent/plugins and a check file underneath etc/sensu/conf.d

Set off an alarm

Install the requirements.txt dependencies and run app.py to dump 30,000 messages into a queue to trigger a warning. Do it again to trigger a critical alert.
