I came a cross this post and was pleased to see some one made a nice .xml file for using the package dhcp-snmp. I haven't found anything else that could help me.
I downloaded the .xml file and tried importing it, cacti didn't show me the messages I was hoping to see "adding template ...", you probably know waht I mean.
I'm using the latest cact at the moment, which is 0.8.6h.
After some experimenting with the .xml file I finally noticed it's not a .xml template for a graph or data objects. It actually is a .xml "data query template" file. Which I placed at the <path_cacti>/resource/snmp_queries/ location and added it as a query file to cacti.
As you might have noticed I'm "new" to cacti, because I recently installed it and still getting new ideas to put into cacti.
I've been toying around with all kinds of different ways to get the info I wanted out of SNMP and finally managed to generate a nice graph.
I just finished the template and haven't had much testing yet.. The graph is included at this post.
I also included my graph template, so people who're interessted on this topic can try it out themselves. Maybe more experianced people could have a look at this and comment to this?
Before I forget: Tnx CdG for posting this .xml file, it did help me alot to go
investigate and understand cacti a bit more
