Description
This article describes how to monitor the CPU and memory status of each VDOM.
Scope
Any supported version of FortiOS.
Solution
Download the SNMP OID file from System->SNMP:
After, download an MIB importer tool. This article will use the Paessler MIB importer.
Import the MIB file in the MIB importer tool. It will now be possible to withdraw the OID value for a specific object.
To monitor a specific VDOM's CPU/memory usage:
- OID 1.3.6.1.4.1.12356.101.3.2.1.1.5.x, where the 'x' is the snmp-index number for that specific vdom
- OID 1.3.6.1.4.1.12356.101.3.2.1.1.6.x, where the 'x' is the snmp-index number for that specific vdom
Follow the steps below to check the snmp-index of specific VDOM.
Create the following configuration in the FortiGate CLI:
# config global
config system vdom-property
sh
edit "root"
set description "property limits for vdom root"
set snmp-index 1
next
edit "VPN"
set description "property limits for vdom VPN"
set snmp-index 2
next
Below is the CPU/memory status of an example Root VDOM:
