Hi,

I am new to Sense.

When I was checking old posts, I found this script: [https://github.com/sensu/sensu-plugin/blob/master/lib/sensu-handler.rb#L109](https://www.google.com/url?q=https%3A%2F%2Fgithub.com%2Fsensu%2Fsensu-plugin%2Fblob%2Fmaster%2Flib%2Fsensu-handler.rb%23L109&sa=D&sntz=1&usg=AFQjCNHx_RnsuVBhzmLUOzjQMGsdbhy8uA)

If the dependencies has several hosts and some services, is it possible to use this script? If so, how can I use it?

Thanks in advance

Nobuo

Most of the handlers available for sensu inherit that class:  
[https://github.com/sensu/sensu-community-plugins/blob/master/handlers/notification/mailer.rb#L34](https://github.com/sensu/sensu-community-plugins/blob/master/handlers/notification/mailer.rb#L34)

Here are the docs on how to configure checks:  
[http://sensuapp.org/docs/0.17/checks](http://sensuapp.org/docs/0.17/checks)

Although they do not reference dependencies...

But per the code, the dependencies is an array of check\_host/check\_name values.

I've added a PR to document this.
