FortiAnalyzer SQL database delete and rebuild

Technical Note: FortiAnalyzer SQL database delete and rebuildProducts

FortiAnalyzer v5.0

FortiAnalyzer v5.2

Description

Occasionally an upgrade does not correctly update the SQL database and reporting will cease to function properly due to missing/misnamed columns and/or indexes.

 

“exec sql-local rebuild-db” is the first option, but if that does not resolve the issue then deleting and rebuilding of the database is the next step.

Solution

 

Remove and re-create the SQL db:

 

1) Change operation mode to collector

 

config system global

set log-mode collector

end

 

2) Disable SQL and remove the current database

 

config system sql

set status disable

end

 

execute sql-local remove-db

 

3) Re-enable SQL

 

config system sql

set status local

end

 

4) Change operation mode back to analyser

 

config system global

set log-mode analyzer

end

 

5) Rebuild database

 

exec sql-local rebuild-db

 

 

 

Notes:

 

(1) The rebuild-db command causes the unit to reboot and the rebuild starts when the unit comes back up.

 

(2) Use the command 'diag sql status rebuild-db' to show the status of the rebuild.

 

(3) The time required to rebuild the database depends on the amount of logs stored on the unit.

 

(4) Although this procedure does not remove any log files it is recommended to backup log files beforehand as a precaution.
