Description This article describes how to monitor disk usage with SNMP OIDs.
Scope FortiGate.
Solution

The following OIDs are used to monitor disk usage with SNMP OIDs.


FORTINET-FORTIGATE-MIB:fortinet.fnFortiGateMib.fgSystem.fgSystemInfo.fgSysDiskUsage1.3.6.1.4.1.12356.101.4.1.6 <- Current hard disk usage (MB).
FORTINET-FORTIGATE-MIB:fortinet.fnFortiGateMib.fgSystem.fgSystemInfo.fgSysDiskCapacity1.3.6.1.4.1.12356.101.4.1.7
<- Total hard disk capacity (MB).


FORTINET-CORE-MIB:fortinet.fortinetCoreMib.fnCommon.fnTraps.fnTrapsPrefix.fnTrapLogDiskThreshold1.3.6.1.4.1.12356.100.1.3.0.103

<- This oid will send the trap when the threshold is reached.

 

The threshold can be set as below :


# config log disk setting
    set full-first-warning-threshold {integer} --> (1 - 98, default = 75).
    set full-second-warning-threshold {integer} --> (2 - 99, default = 90)
    set full-final-warning-threshold {integer} --> (3 - 100, default = 95).
end
