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. Since I typically don’t have time to manually run a backup (and why would I want to do something the hard way anyhow?) I decided it was time to automate the task. The first issue was what to name the backup files.
