1. Download check_snmp_int.pl plugin (accessory download)

2. Plug-ins are developed using Perl to determine if Perl is installed

Installation: Yum install-y perl*

Use Check_snmp_int.pl-h to view help if the following issues occur:

" Can ' t locate net/snmp.pm in @INC (@INC contains:/usr/local/lib64/perl5/usr/local/share/perl5/usr/lib64/perl5/ Vendor_prl/usr/share/perl5/vendor_perl/usr/lib64/perl5/usr/share/perl5.) At./check_snmp_int.pl Line. "

Solution: perl-mcpan-e ' Install Net::snmp '

3. Define Command

Define Command{command_name check-snmp-intcommand_line $USER 1$/check_snmp_int.pl-h $HOSTADDRESS $-C $ARG 1$ $ARG 2$}

4. Define the host and service:

Define Host{usegeneric-switchhost_namecisco3560aliascisco3560address192.168.6.254hostgroupsswitches}

define service{        use                     generic-service         host_name               cisco3560        service_description     GigabitEthernet0/24        check_command           check-snmp-int!public!-n  ' ^gigabitethernet0/24$ '  -k -f   -w 20000,50000 -c 100000,200000          }define service{        use                      generic-service        host_name               cisco3560        service_description     Vlan100        check_command           check-snmp-int!public!-n  ' ^vlan100$ '  -k -f   -w  20000,50000 -c 100000,200000         }

Note: The definition service is: The max_check_attempts parameter is recommended to be modified to 6 (default is 4), because this plug-in must run at least 3 to 4 times or more to be normal, read the data once and record in the temporary file, as follows:
