The profile database contains CPU utilization values from day one. At midnight on the second day, the CPU utilization values from the daily database will be merged with the profile database using a weighted average formula:

New value = (Old value x Old weight) + (New value x New weight) / (Old weight + New weight)

The weight is determined by the number of days in each database. In this case, the profile database has one day of data and the daily database has one day of data, so the weight is equal for both databases. Therefore, the formula simplifies to:

New value = (Old value + New value) / 2

In the profile database, in the Hour of Day column where 9 is the value, the updated minimum, maximum, and average CPU utilization values are:

Min CPU Util = (32.31 + 32.31) / 2 = 32.31 Max CPU Util = (33.50 + 33.50) / 2 = 33.50 AVG CPU Util = (32.67 + 32.67) / 2 = 32.67

The statements about collector communication with the FortiSIEM cluster that are true are:

Collectors communicate periodically with the supervisor node. Collectors send heartbeat messages to the supervisor every 30 seconds to report their status and configuration.

The supervisor periodically checks the health of the collector. The supervisor monitors the heartbeat messages from collectors and alerts if there is any issue with their connectivity or performance.

Collectors upload event data to any node in the worker upload list, but report their health directly to the supervisor node. Collectors use a round-robin algorithm to distribute event data among worker nodes in the worker upload list, which is provided by the supervisor during registration. However, collectors only report their health and status to the supervisor node.

The windows device is still in the CMDB, even though the administrator uninstalled the windows agent, because the device must be deleted manually from the CMDB. Uninstalling the windows agent does not automatically remove the device from the CMDB, as there may be other sources of data for the device, such as SNMP or syslog. To delete the device from the CMDB, the administrator must go to CMDB > Devices > All Devices, select the device, and click Delete.

The processes associated with Machine Learning/AI on FortiSIEM are phFortiInsightAI and phAnomaly. phFortiInsightAI is responsible for detecting anomalous user behavior using UEBA (User and Entity Behavior Analytics) techniques. phAnomaly is responsible for detecting anomalous network behavior using NTA (Network Traffic Analysis) techniques.

The collector processes are dependent on the registration with the supervisor. The phMonitor process is responsible for registering the collector to the supervisor and monitoring the health of other processes. After the registration is successful, the phMonitor will start the other processes on the collector.
