The fdn.log file in FortiSOAR contains logs related to license synchronization activities. This log file records events and errors associated with license checks and synchronization with Fortinet's licensing servers, ensuring that the FortiSOAR instance remains compliant with licensing requirements. Monitoring fdn.log can help administrators troubleshoot issues related to license synchronization and ensure the system operates within the licensed limits​.

In a FortiSOAR HA configuration, certain ports must be open for communication between nodes. Port 5432 is required for PostgreSQL database communication, which is essential for data replication between HA nodes. Port 9200 is used by Elasticsearch, which FortiSOAR leverages for indexing and search functions across the nodes. These ports must be accessible between nodes to ensure seamless operation and data consistency within the cluster​.

The FortiSOAR queue and shift management feature enables several key activities for managing shifts and queues. Administrators can initiate shift handovers, allowing for smooth transitions between shift leads and members. They can also designate specific roles within shifts, including shift leads and members, to define responsibilities. Additionally, queue rules can be established based on certain conditions, ensuring that incidents and tasks are assigned according to predefined criteria, which helps streamline operations and improve response times​.

In a FortiSOAR High Availability (HA) cluster setup with an externalized PostgreSQL database, it is necessary to configure the database server to allow incoming connections from all FortiSOAR nodes. This configuration involves modifying the pg_hba.conf file to set up host-based authentication and control which IP addresses can connect. The postgresql.conf file must also be adjusted to enable listening on all necessary IP addresses, which is critical for FortiSOAR nodes to connect to the database server securely and reliably. Together, these configurations ensure that all FortiSOAR nodes can access the database, facilitating effective HA functionality​.

In FortiSOAR, appliance users are accounts that represent non-human entities, such as system processes or integrations. These users do not require login IDs and therefore do not contribute to the licensing user count. Appliance users are configured for backend tasks or to interact with external systems, enabling automated processes without consuming standard user licenses. This approach optimizes system resources and keeps licensing costs manageable​.

When the PostgreSQL database is externalized in FortiSOAR, certain HA-related CLI commands become inapplicable. Specifically, the csada ha firedrill command, which is used to test the integrity of the HA cluster by simulating failures, is not applicable in scenarios where the database is managed outside FortiSOAR. Externalizing the database changes how FortiSOAR manages database connections, making some internal commands like firedrill redundant​.
