I'm struggling a little bit with this one. Some of my puppet nodes have lights-out management. For those that do, I want to put the IP address of their iLOM card in Hiera and have that appear as the notes_url in nagios_host{}. This works well for hosts that *do* have iLOM, but for those with no Hiera variable called ilom I don't want notes_url to be defined at all. Setting notes_url => undef doesn't work because it is still written out in the nagios config and the url appears clickable, but with no link behind it. Setting notes_url => absent actually sets it to the string 'absent'. Is there an elegant way of handling this so my iLOM-able hosts have clickable iLOM links in Nagios while the non-iLOM-able hosts don't have anything at all?
