Good plugin!

works with Cisco 1800,1900,880
Dell Powerconnect 2848

But i have a problem with pnp4nagios:

PNP Error
"/usr/local/pnp4nagios/var/perfdata/XXX/Interface_Status.xml" not found.
Despite PNP4Nagios works with others plugins.

Hi pierrooo,
Thanks for the feedback.
The plugin should work correctly with pnp4nagios. Moreover, pnp4nagios is the recommended graphing solution to use with this plugin.
Also, you may use the option -h "host alias" and specify the hostname used in the nagios config. Usually, with pnp4nagios the checkcommand would start with ./ -H $HOSTADDRESS$ -h $HOSTNAME$ ...
If you still face this problem, please go to the dedicated forum ( and post some details about it.

I configured and monitored 3Com Switches (2829 and 2849) and Sonicwall NSA2400 successfully.

While I'm configuring all this stuff I found some troubles that I solved by myself:

1.- 3Com Switches (2849) labels contains ", " (comma and space) and this caused broken links to pnp4nagios graphs cause XML an RRD files generated translated this sequence to "._".
To solve this I added (line 1855) the following line to "GenerateInterfaceTableData" function inside file:

$servicename =~ s/, /\._/g;

2.- Blank characters in Nagios Hostnames are visualized as "Q20" in "Node Selector" drop down menu. I solved this adding the following line to "nodename" function inside /usr/local/interfacetable_v3t/share/tables/index.php file:

$filename = preg_replace("/(Q20)/", " ", $filename);

Hope this help somebody.

Thanx for this awesome plugin!!!

Thanks for your feedback.
I will implement your change in the next release of the plugin.
Best regards,

By far the best, most comprehensive interface plug-in for large environments. I really had problems finding anything to compete with this... Performance degraded [on the Cisco switch] when running check_snmp_netint against all desired/monitored interfaces, and even then, I couldn't control the output as much as I can with this. Just fantastic. Thanks!
Excellent plugin.

It's not possible to monitor NetApp FAS systems. I get the error: "[ERROR] Could not read ifOctetIn information from host "x.y.z.q" with snmp".

This post explains why.
Owner's reply

Full support of NetApp Filers is implemented and will be available in the next release of the plugin (0.05)
Thanks for the feedback.
