check snmp traffic total

This is a nagios plugin (or it can be run as a standalone script) that will monitor the total traffic over an interface. Interface stats reset when a system reboots. To account for this, the script will record the interface traffic to a database after each run, and sum between reboots. This should only be used as a guide, and may not be an accuate representation of actual traffic passing across the wire.

To use it as a stand alone as CLI tool, run the script with --help for the full list of options.

The script will exit code > 0 if the threshold of in/out is exceeded within the time period. A summary is also printed. This script does not need to be run via Nagios, and could be used stand alone, or invoked via cron.

This project was moved from google code (http://code.google.com/p/checksnmptraffic/).
