From the CLI of the Nagios XI machine, can you share the output of an snmpwalk for the associated tree (replace 10.x.x.x with your host's IP):

Code: Select all

snmpwalk -mALL -v2c -cjawwal-snmp 10.x.x.x 1.3.6.1.2.1.25.2.3.1.3

Some drives simply cannot be monitored by the net-snmp agent. You might try adding the following directive to the remote machine's /etc/snmpd.conf to see if it allows the other disks to appear:

Code: Select all

includeAllDisks  10000

You might also try leveraging this re-write of the plugin I did to leverage the UCD-SNMP-MIB module for disk checks. It works in roughly the same way as check_snmp_storage_wizard.pl:
https://github.com/mcapra/nagios-check_snmp_storage_ucd

It has similar requirements:

Code: Select all

# This uses the UCD-SNMP-MIB module to accurately check mounts greater than 2TB in size. 
#
# Your remote server's /etc/snmpd.conf config file must include:
#	includeAllDisks  10000
# To include all mounts that are at least 10MB in size. This directive can be modified to include all disks as well.
