I have configrd check_ifutil on debian jessie 8.5...it gives output of ethernet on locally but in nagios...update the old value very very slow...like...if eth tx:450KBps..and server traffic increases to 50MBps/sec...then this plugin return...only 5MBps...until i have to manually run the script on server then nagios update its value to 50MBps....plz solve this

Seems like a cool plugin but I cant get rid of the 'unuinitialized' error:

perl ./setup/temp/check_ifutil.pl -i eth0 -w 10 -c 20 -b 10Mbps

Thank you so much. Was very usefull
I would like to integrate this script with nagiosgraph too. Can someone give some step by step informations.
I`m new with Nagios and Nagiosgraph. I managed to install and configure Nagios and Nagiosgraph but now I don`t know how to integrate this script. I need this script to monitor localhost ethernet interface.

Thanks in advance!

Great job!

Handy script, but should mention that it runs on linux only - it reads /proc/net/dev, so unfortunately it won't help you monitor a switch or other network device.
Nice little plugin. Since XI has its own grapher, I only had to integrate this plugin into nagiosxi and it just worked. Thanks!

Hi,

I have searched a lot for a working plugin like this to integrate with nagios 3.4 and nagiosgraph.
From many tested this is the only one working for me that is also generating perfdata.
I have chosed to change my " $bitmod = BYTES; " to " my $bitmod = BITS; " and here is an example of usage in my case: " /usr/bin/perl /root/check_if.pl -i eth1 -w 700m -c 900m -b 1000m " (this is for a gigabit interface)

Nice work for the author!

Thanks for that great script.
The output is something like
RX Bytes: 661GB, TX Bytes: 150GB; RX Speed: 62KBps, TX Speed: 25KBps; OK bandwidth utilization | rx=63021;1152921504606846976;3458764513820540928 tx=25090;1152921504606846976;3458764513820540928

And I could graph it too!
