FortiAnalyzer supports Structured Query Language (SQL) for logging and reporting. The log data is inserted into the SQL database to support data analysis in FortiView, Log View, and Reports. Remote SQL databases are not supported.
The log storage settings define how much FortiAnalyzer disk space to use for the SQL database.
The SQL database is disabled by default when FortiAnalyzer is in Collector mode so logs that require the SQL database are not available in Collector mode unless the SQL database is enabled. See Two operation modes.
