Plugin created for capturing RX and TX statistics from Linux OS interfaces. Useful to analyze package tendencies, such as total transfered, dropped, framed and overrun packets. This plugin follows a very simple approach and outputs a nagios formatted metric syntax for chart creation.
IMPORTANT: This script relies on `ifconfig` command, so soon it will be outdated but I hope to rewrite using a better replacement like ethtool or ip.
To better explain the output:
- RX: Received packets - TX: Transfered packets - errors: Packets which could not be transfered/received due errors - dropped: Normally indicates configuration/communication errors (eg: One side operating in half-duplex and the other in full-duplex) - overruns: The interface has two buffers, one for transmit and the other one for receive and when one of these buffers reachs its limit the surplus packets are discarted as 'overrruns' - frame: Malformed frames - carrier: Physical link error. Very common in HUBS, should not never occur with switch environments.
