Collecting CLI Data from Cisco Devices Via HTTP

I always try to approach technical challenges with the thought that “just because something can’t be done doesn’t mean it can’t be done”.   Sure enough I had a problem like this cross my desk again the other day.   I wanted a simple way to get the number of active calls on a handful of MGCP PRI gateway routers.  Unfortunately I couldn’t find a single SNMP data point for this information.  I knew IOS routers had an HTTP interface so I started checking around to see how easy it would be to script against.

I recently setup a system to manage our companies IP addresses. This was an open source PHP application that ran in Apache and used MySQL for its database.

The first issue was what to name the backup files.
