​​Charm Authoring Feedback

​​The mission

​​This all started because I wanted to make the charm Martin did work generically and I couldn’t figure out how the @#$%$# the nagios setup worked. I couldn’t get the right combo of hooks, nrpe, nagios, which interface does what…and decided I’d try to build from scratch using layers and grabbing interfaces other folks had already written. 

​​Getting setup

​​The instructions to setup directories doesn’t seem to tell me where to actually stick my charm code

​​I grabbed a tarball of a generic charm create from lazypower and used that to start with.

  • ​​I have an interface layer form cmars…how do I include it? Checking the docs
