Quality 0%


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

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



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

cd examples/ssl
./ generate
knife data bag create sensu

Use the plain-text data bag item:

knife data bag from file sensu ssl.json

Or, encrypt it with your data bag secret. See Encrypt a Data
more information.

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