[c-nsp] graphing bad hop counts

As I could'n find a way of sampling anything related to "ip traffic" with SNMP, I'd suggest that, if supported,  you use an EEM script on your device, this can trigger an action such as an SNMP-Trap, or putting a line in the logging of the device, and you can monitor it.
I'm not such an expert with this EEM scripts, but I know there are a few guys here that could help you.
Because of my ignorance I need to manage the way I know, so in my case I'd just create a script on my cacti server that telnets the device, runs the command I want, cuts the result and creates a graph, then you have also a thresholds plugin for cacti where you can do some other nice things.

Subject: [c-nsp] graphing bad hop counts

Hi,
I'm looking for a way to graph bad hop counts when you issue the "show ip traffic" command.  I have a multicast network and, short of constantly going into devices and issuing that command, there is no way of knowing or being notified (that I know of) as to when the bad hop count is reaching a certain threshold.  Does anyone know of any software or anything that can help me accomplish my goal?  Or alert me in some way when the bad hop count reaches a threshold?  Any help is appreciated.  Thanks.
-Brandon
