Some firmware upgrades might change the SQL schema that indexes logs (analytics). If so, FortiAnalyzer automatically rebuilds the SQL database. During the rebuild, searching and reporting functions are limited.
You rarely need to manually rebuild an SQL database. If you think there might be problems with the SQL database, contact Customer Service & Support before considering a manual rebuild.
You might consider rebuilding the SQL database in the following situations:
- After moving a device to a new ADOM, you might need to rebuild the SQL database in the new ADOM.
- If disk space is running low, you might rebuild the SQL database to try free up disk space.
