# chef-monit  [![Build Status](http://img.shields.io/travis-ci/phlipper/chef-monit.png)](http://travis-ci.org/phlipper/chef-monit)



## Description



Installs the `monit` package from (http://mmonit.com/monit/).



## Requirements



### Supported Platforms



The following platforms are supported by this cookbook, meaning that the recipes run on these platforms without error:



* Ubuntu 12.04, 14.04

* Debian 7.8, 8.0

* RedHat

* CentOS 6.6, 7.1

* Scientific

* Fedora 21

* SUSE

* Amazon



## Recipes



* `monit` - The default recipe. Sets up the service definition and default checks.



## Resources



### `monit_monitrc`



The following will create a monitrc configuration:



```ruby

monit_monitrc "ssh" do

  variables({ category: "system" })

end

```



The `name` parameter must match a file located in your templates directory. In the example above, this would be `ssh.monitrc.erb`.



The `variables` option within the block is optional, and can contain a list of key-value pairs to assign within your template.



## Usage



This cookbook installs the monit components if not present, and pulls updates if they are installed on the system.
