Argument “v6.0.1” isn’t numeric in numeric lt (<)

logo nagios

In nagios, you will encounter this error”Argument “v6.0.1″ isn’t numeric in numeric lt (<)” with plugins like “check_snmp_ *” To solve this problem, just replace:

 

(Net::SNMP->VERSION < 4 )

by

(Net::SNMP->VERSION lt 4 )

On the line number corresdonding to this error in plugins.

This problem is due to the fact that plugins are quite old and libnet-snmp-perl has evolved.
