Output of snmp command with -v option is shown below.

/bin/snmpget -Le -t 1 -r 5 -m CHECKPOINT-MIB -v 3 [authpriv] 10.235.15.20:161 enterprises.2620.1.6.7.6.1.8
External command error: snmpget: Authentication failure (incorrect password, community or key) (Sub-id not found: (top) -> enterprises)

Besides, the following command is generated using Linux snmp wizard to check disk of checkpoint virtual appliance same as above command, what's the implication of error returned from it? What should be done to make it work normally?

check_xi_service_snmp_linux_storage! --login=<user> --passwd=<password> --privpass=<password> --protocols=md5,aes -m "^/$" -w 80 -c 95 -f

(Return code of 127 is out of bounds - plugin may be missing)

I don't see any signs of a corrupt MIB file. It looks like the username or the password is not working so you will need to verify they are correct.

The check_xi_service_snmp_linux_storage command is using this plugin on the server. Make sure it exists and that is is executable by the Nagios user account.

Output of running the following command is shown. It has't run because some arguments are missing? Checked it has permission to execute it (logon user is root).
/usr/local/nagios/libexec/check_snmp_storage_wizard.pl --login=<username> --passwd='pwd' --privpass='pwd' --protocols=md5,aes -m "^/$" -w 70 -c 80 -f

The permissions for the plugin check_snmp_storage_wizard.pl look good and it can run without any errors.

The error could be caused by a special character in the username or password. If you have one, encase the username and password in single quotes ' so they will get passed correctly like the following example. If it fails, I will need to see a System Profile showing the settings.
