DESCRIPTION

Provides LWRP's and service recipes to install and configure Sensu, a monitoring framework.

This cookbook provides the building blocks for creating a monitoring cookbook specific to your environment (wrapper). Without such a wrapper, no Sensu configuration files will be created for your nodes.

An example wrapper cookbook can be found HERE.

How to Write Reusable Chef Cookbooks

TESTING

This cookbook comes with a Gemfile, Cheffile, and a Vagrantfile for testing and evaluating Sensu.

xamples
install bundler
le install
arian-chef install
ant up
ant ssh

COOKBOOK DEPENDENCIES

• APT
• YUM
• Windows
• RabbitMQ
• RedisIO

REQUIREMENTS

SSL configuration

Running Sensu with SSL is recommended; this cookbook uses a data bag sensu, with an item ssl, containing the SSL certificates required. Sensu data bag items may be encrypted. This cookbook comes with a tool to generate the certificates and data bag item. If the integrity of the certificates is ever compromised, you must regenerate and redeploy them.

xamples/ssl
l_certs.sh generate
e data bag create sensu

Use the plain-text data bag item:

e data bag from file sensu ssl.json

Or, encrypted it with your data bag secret. See Encrypt a Data Bag for more information.

e data bag --secret-file /path/to/your/secret from file sensu ssl.json

shell
l_certs.sh clean

RECIPES

sensu::default

Installs Sensu and creates a base configuration file, intended to be extended. This recipe must be included before any of the Sensu LWRP's can be used. This recipe does not enable or start any services.

sensu::rabbitmq

Installs and configures RabbitMQ for Sensu, from configuring SSL to creating a vhost and credentials. This recipe relies heavily on the community RabbitMQ cookbook LWRP's.

sensu::redis

Installs and configures Redis for Sensu. This recipe uses the RedisIO cookbook and installs Redis from source.

sensu::server_service

Enables and starts the Sensu server.

sensu::client_service

Enables and starts the Sensu client.

sensu::api_service

Enables and starts the Sensu API.

sensu::dashboard_service

Enables and starts the Sensu dashboard.
