Cisco Network Monitor (CPU, I/O & Processor Memory, UP Ethernet Interface Density)
This is a script written in Python 2.7.3 which collects data (CPU Utilization, Used Processor Memory, Used IO Memory, Number of UP Ethernet Interfaces) from all the Cisco devices in a network and exports this info to txt files, importable into Excel for creating network performance charts. It also extracts useful info about each device (in the NetworkDevices.txt file) or Top 3 resource intensive devices in the network. Each network query is timestamped. Requires Python 2.7. Tested on Linux.
