Hi

 

On our FortiAnalyzer (v5.4) I see the following error messages:

 

Deleted 2 log files with total size 400.0MB to enforce the retention policy of Adom root.

 

However it is only using 47% of disk space.  I think it is to do with the retention policy but not sure what, any ideas please?

 

In settings it is set to only delete logs after it is 95% full.

I think it's because you can configure  maximum retention day, if they are older, they are deleted.

 

Based on the informations on your post, you keep log 365 days
