What is fsSysDiskCapacity?

This gauge reports the total on-board disk capacity of the FortiSwitch, in kilobytes, on models that include a disk. It's the reference value admins pair with fsSysDiskUsage to figure out remaining free space for logging or firmware storage. For example, a value of 0 would indicate that this particular switch model has no local disk installed.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.12356.106.4.1.6
snmpwalk -v2c -c public <target> FORTINET-FORTISWITCH-MIB::fsSysDiskCapacity

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.12356.106.4.1.6.1
snmpget -v2c -c public <target> FORTINET-FORTISWITCH-MIB::fsSysDiskCapacity.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> fsSysDiskCapacity.1
