InFortiSIEM baselining, anhourly bucketis used to maintainhourly-specific statistical baselines. This helps detect anomalies by comparing current activity against historical norms foreach hour of the day, separately forweekdays and weekends.

The system maintainshourly profiles, ensuring that anomalies are detected based on similar timeframes. This approach prevents false positives due to natural variations in network activity across different times of the day and different days of the week.

Afterregistration, collectors maintaincontinuous communicationwith theSupervisorto ensure properevent processing, system health monitoring, and failover handling. The two key reasons collectors communicate with the Supervisor are:

1.To upload event data if a worker is down

If aworker node fails, thecollector can temporarily store event logsand then forward them to the Supervisor.

This ensuresevent continuityeven during infrastructure issues.

2.To report its own health status

Thecollector sends health reportsto theSupervisor, including resource usage, connectivity status, and operational logs.

This helps FortiSIEM trackcollector uptime and performance.

The phProvisionCollector command is used to register a collector to the supervisor in FortiSIEM. The correct syntax requires:

● User → The admin username for authentication.

● Password → The password for authentication.

● Super IP → The IP address of the supervisor, which manages the collector.

● Organization → The organization to which the collector belongs.

● Worker Name → The name of the worker node responsible for handling events from this collector.
