Does the job
by kevinhe, July 31, 2020

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.


Great Plugin, but ...
by marzlarz, July 31, 2013

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?


Good display of errors, but reporting function does not work
by kotterbein, May 31, 2013

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.
