Your existing DB probably doesn't match what hiera-mysql is expecting, but maybe it's something you could refactor:

I have a MySQL database table that effectively holds key-value pairs which link each node to its parent (ESXi hypervisor). I want to use this information to set the Nagios parent, which is easy to do, client-side.

I'm not sure what the best approach is. I considered writing a custom fact that does a brief MySQL query to discover that node's parent. I wasn't able to find any code I was prepared to run in production - is there a neater way of using a ruby module to query MySQL? The example on this page is dirty.

Alternatively, is there any way to access this data server-side that can be accessed on a per-node basis?

Cheers,
Jonathan
