How can you reduce load on FortiAnalyzer's FortiView module?

Disabling the resolve-ip feature is an effective way to reduce load on FortiAnalyzer's FortiView module. When the resolve-ip feature is enabled, FortiAnalyzer performs extra processing to resolve IP addresses to their corresponding hostnames. This process can consume significant system resources, especially in environments with a large number of logs being analyzed or when dealing with frequent IP address changes. By turning off this feature, FortiAnalyzer focuses on processing the raw log data without the additional overhead of resolving hostnames, thus improving performance and responsiveness within FortiView.

The other methods mentioned, such as enabling local DNS resolution, increasing hardware resources, or moving logs to external storage, while potentially beneficial for improving performance or managing resources, do not directly target the load generated by hostname resolution in FortiView. Enabling local DNS resolution could actually add more overhead. Increasing hardware resources and moving logs to external storage may alleviate some load but are more about scaling or managing capacity rather than addressing the specific load caused by the resolve-ip feature in FortiView.
