Where are the primary log files located in a typical Sansus installation, and what information do they contain?

Sansus log files are typically found in `/var/log/sansus/` or a similar directory specified during installation. Key logs include `sansus.log` (general application events), `error.log` (error messages, including fatal errors), and logs specific to individual Sansus modules (e.g., database logs, network logs). These logs contain timestamps, error codes, and descriptions of events leading up to the error.
