What is required to use the log fetcher on FortiAnalyzer?

To utilize the log fetcher on FortiAnalyzer, it is essential to have two FortiAnalyzers running the same firmware. This requirement ensures compatibility and seamless communication between the devices. Having identical firmware versions helps prevent discrepancies in data management, logging protocols, and feature uniformity, allowing for effective log fetching and processing.

When two FortiAnalyzers are operating with the same firmware, they can exchange logs accurately, providing comprehensive visibility and analysis of the data across the network. This harmonization is crucial for maintaining a robust logging infrastructure and enabling consistent performance when analyzing security events and traffic patterns.

Other options, while they may involve configurations of Fortinet devices, do not fulfill the specific requirement needed for employing the log fetcher on FortiAnalyzer effectively. For example, using two devices with different firmware would likely lead to issues with data interpretation and compatibility. Similarly, while a FortiGate device configured for logging is integral to generating logs, it does not directly relate to the log fetching feature between two FortiAnalyzers, which is fundamentally tied to their firmware alignment.
