check_iftraffic_nrpe.py

This is a Nagios plugin to check network traffic with NRPE on Linux. This script has been created because I like writing Python scripts.

Note that only myself tested this script so far. Feedbacks are very welcome.

Prerequisites

• Python 2.x
• The python-argparse library

Compatibility

This script has been tested under Python 2.x only. I don't know if it works unders Python 3.

This script has been tested under Nagios 3.x only. I have no idea how it behaves with older versions.

Usage examples

How to get some help:

check_iftraffic_nrpe.py --help

Query all interfaces except the loopback interface:

check_iftraffic_nrpe.py -x lo

Query only eth1:

check_iftraffic_nrpe.py -i eth1

Set warning value to 80% (default: warning=85, critical=98):

check_iftraffic_nrpe.py -w 80

Define a Gigabit interface (the value must be in bytes):

check_iftraffic_nrpe.py --bandwidth=131072000
