I've asked the owner to modify the regex when searching for interface names. The script at the moment only matches interfaces index numbers 1-9.
http://www.net-snmp.org/docs/mibs/interfaces.html
shows ifTable indexes can be 1-2147483647.

I've requested the regex under line 69:
if ( $line =~ m/$OID_networkInterfaces\.([0-9]) = STRING: (.*)/ )

to be modified to

if ( $line =~ m/$OID_networkInterfaces\.([0-9]){1,10} = STRING: (.*)/ )


You can obviously do this yourself with a text editor when importing to nagios.
This is a great plugin. It makes monitoring our interfaces very easy.

The only issue we are having is that sometimes it responds with:

"Cannot identify the eth# network interface"

When I snmpwalk the MIBS from the check_interface.pl, I see the interface in question. Any ideas?
Overall it has good reporting of iferrors, but we are unable to graph the errors accordingly, using the -f function- only reports back 0's, not the actual error counts.
