Enable the SNMP agent on the FortiAnalyzer device so it can send traps to and receive queries from the computer that is designated as its SNMP manager. This allows for monitoring the FortiAnalyzer with an SNMP manager.
SNMP has two parts - the SNMP agent that is sending traps, and the SNMP manager that monitors those traps. The SNMP communities on monitored FortiGate devices are hard coded and configured by the FortiAnalyzer system - they are not user configurable.
The FortiAnalyzer SNMP implementation is read-only — SNMP v1, v2c, and v3 compliant SNMP manager applications, such as those on your local computer, have read-only access to FortiAnalyzer system information and can receive FortiAnalyzer system traps.
