This article describes the OOIDs to add in the SNMP manager in order to Monitor CPU and Memory utilization of WAF.

Scope

FortiWeb.

Solution

To enable SNMP in FortiWeb:

Navigate to System > Config > SNMP which will enable the FortiWeb device SNMP agent to allow queries for the Device information and to send alarms or event messages in the form of Traps to the SNMP manager.

Enable the traps for the SNMP events that should be Notified by FortiWeb to SNMP managers:

Enable the traps for the SNMP events that should be Notified by FortiWeb to SNMP managers.

This article provides the below OOID if the requirement is to Monitor the CPU and Memory utilization of WAF.

For details about supported traps and queries, follow the below link:
SNMP traps & queries

Below are OOID for CPU and Memory utilization of WAF :

fwSysMemUsage : .1.3.6.1.4.1.12356.107.2.1.7
fwSysMemCapacity: .1.3.6.1.4.1.12356.107.2.1.8
fwSysCpuFreq: .1.3.6.1.4.1.12356.107.2.1.6
fwSysCpuUsage: .1.3.6.1.4.1.12356.107.2.1.5
fwSysOpMode: .1.3.6.1.4.1.12356.107.2.1.4

To get a maximum OIDs of FortiWeb, follow these steps:

  1. Log in to the FortiWeb appliance.
  2. Go to System -> Config -> SNMP.
  3. Select the following links to download the MIB files:
    • Download the FortiWeb MIB File.
    • Download the Fortinet Core MIB File.

To get a maximum OIDs of FortiWeb, follow these steps.

Once downloaded, compile these MIB files into the SNMP manager (or) open the FortiWEB MIB files in an MIB browser which can be downloaded for free from the internet.
