Re: [Nagios-users] check_snmp_int.pl regex problems

Hi,

The big problem with Windows SNMP agent, is that is puts special caracters you don't see in interface description, so putting "Network Connection$" won't work because there are control caracters after "Connection". (maybe "Connection[ [:cntrl:]]*$" would work).

Single or double quote don't matter by the way. It's just to be sure the shell won't interpret caracters like ";" or "&"

Your idea to check interface without "#" in it was good but not the regexp. Try :
"^Intel[^2#]*$"

Which means : starts (^) with "Intel" and ends ($) with a string containing any caracters that are not 2 or # ([^2#]*)

Hi Dan,

Thanks for the suggestion. That did not work, it still doesn't like the $. I have gone ahead and modified one of the check_snmp scripts to check it based on each interfaces oid. I can get the info I need now, just takes a bit more work.
