Which command is used to diagnose the hcache size on the file system?

The command used to diagnose the hcache size on the file system is "diagnose sql show hcache-size." This command is specifically designed to assess and display the size of the hcache within the FortiAnalyzer system.

The term "hcache" refers to a caching mechanism that helps improve the performance of database queries in FortiAnalyzer. By running this command, administrators can gain insights into the current size and status of this cache, allowing them to optimize system performance and resource management effectively. The output generated by this command will provide valuable information regarding the cache’s utilization, which can help in adjusting its size or understanding its impact on system operations.

Other options do not provide the same functionality related to diagnosing the hcache size. While they may pertain to hcache in some manner, they do not specifically focus on retrieving the size of the hcache as directly and effectively as the chosen command does.
