Please help me!In nagios.log file I have this:xec/nagios/check_snmp_if: "Use of uninitialized value in concatenation (.) or string at (eval 1) line 154,". Maybe somebody know what problem with my nagios.Thank a lot for your help.
Query "Use of uninitialized value in concatenation" on Google. It looks like this may be a Perl problem. can you check what version of perl you are running, the OS, nagios and nagios plugin versions.
