Which process caches logs on FortiGate when FortiAnalyzer is not readable?

The processlogfiledin FortiGate units with an SSD disk is responsible for buffering logs when FortiAnalyzer is unreachable. If the connection to FortiAnalyzer is lost and the memory log buffer is full,logfiledallows logs to be buffered on disk. These logs are then sent to FortiAnalyzer once the connection is restored. This reliable logging mechanism ensures that logs are not lost during periods when FortiAnalyzer is not reachable, thereby maintaining log integrity and continuity.References:FortiOS 7.4.1 Administration Guide, "Log Buffering" and "Reliable Logging" sections.
