when i tried to run below command on NagiosXI host
#./check_snmp_storage.pl -H 192.168.2.1 -C public -m "^/$" -w 2 -c 4

it throws below error
ERROR: Description/Type table : Requested table is empty or does not exist

ERROR: Description/Type table : No response from remote host '192.168.2.1'

First troubleshooting steps you should do is an SNMPwalk

snmpwalk <host IP> -c <comm string> -v<version>

Is this successful?
