Your source to use Sensu with SaltStack.
There is already a SaltStack Formula in the SaltStack community repository, saltstack-formulas/sensu-formula.
In addition, you may want to use the Formulas for RabbitMQ and Redis.
This project's maintainers decided to start over due to the lack of recent maintenance. You can still pull the old code by checking out the following commit 69ea0682e86ebc0a2b3ce70dd13a7abddff3f0b8 available here or by going to the legacy branch.
