Check bandwidth checks if the current bitrate of a network interface differs from the average for that interface. It is very useful for monitoring ISP uplinks, which tend to have a very stable average when everything is running ok.

check_bandwidth is a plugin written in C that relies on the net-snmp library to collect interface counters and calculate the bitrate. Check bandwidth stores the last five counters for input/output for the specified interface in a binary file in /tmp. When the plugin runs for the sixth time, it will have the last five readings as data to calculate the average. If the current bitrate differs from the average more than 25%, the plugin yields WARNING, if it differs more than 35%, the plugin yields CRITICAL. This is very useful for monitoring ISPs uplinks.
