Try installing the missing perl module by running this.

Code: Select all

 yum install perl-Exporter -y

I have the same problem on a EL7 system - details below.
The nagiosXI version is the offline one: 5.2.0

This issue came up in the past here with a pretty in depth explanation - https://support.nagios.com/forum/viewto ... 10#p157999

I believe the final fix was changing these two lines, could you try making two changes to your SNMP_Session.pm -

Code: Select all

Line 149

Socket6->import(qw(pack_sockaddr_in6 inet_pton getaddrinfo));

Line 604

Socket6->import(qw(pack_sockaddr_in6 inet_pton getaddrinfo));

Replace both of them with -

Code: Select all

Socket6->import(qw(inet_pton getaddrinfo inet_ntop));

This may work for you. Let us know the result.
