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
This cookbook comes with a Gemfile, Cheffile, and a Vagrantfile for testing and evaluating Sensu.
cd examples
gem install bundler
bundle install
librarian-chef install
vagrant up
vagrant ssh
Running Sensu with SSL is recommended, this cookbook uses a data bag
sensu
, with an item ssl
, containing the SSL certificates required.
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.
cd examples/ssl
./ssl_certs.sh generate
knife data bag create sensu
knife data bag from file sensu ssl.json
./ssl_certs.sh clean
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.
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.
Installs and configures Redis for Sensu. This recipe uses the RedisIO cookbook and installs Redis from source.
Enables and starts the Sensu server.
Enables and starts the Sensu client.
Enables and starts the Sensu API.
Enables and starts the Sensu dashboard.
