====== Log Files ======

Synchronet's [[server:|servers]] and [[util:|utilities]] can output status to a lot of different log files that are helpful for monitoring activity and debugging issues:

^ File                               ^ Purpose ^
| ''[[dir:ctrl]]/csts.tab''          | Cumulative statistics log, parsed/displayed by Synchronet and its utilities (e.g. [[util:SLOG]], [[module:slog]].js, [[sbbsctrl]]) |
| ''[[dir:data]]/error.log''         | Unexpected events that should be addressed by the sysop |
| ''[[dir:data]]/events.log''        | Event Thread activity from the [[server:Terminal]] Server |
| ''[[dir:data]]/crash.log''         | User activity before suspected crashes of [[server:Terminal]] Server nodes |
| ''[[dir:data]]/guru.log''          | User chat sessions with The Guru |
| ''[[dir:data]]/hack.log''          | Suspected hack attempts |
| ''[[dir:data]]/hungup.log''        | Users that disconnected while executing an external program on the [[server:Terminal]] Server |
| ''[[dir:data]]/logon.lst''         | Legacy list of terminal server user logons, preformatted |
| ''[[dir:data]]/logon.jsonl''       | List of terminal server user logons, used by [[module:logonlist]] module |
| ''[[dir:data]]/sbbsecho.log''      | [[util:SBBSecho]] (FidoNet EchoMail program) activity |
| ''[[dir:data]]/sendmail.log''      | Email sending activity from the [[module:sendmail]] module |
| ''[[dir:data]]/spam.log''          | Suspected SPAM delivery attempts to the [[server:Mail]] Server |
| ''[[dir:data]]/logs/http-*.log''   | HTTP access log from the [[server:Web]] Server |
| ''[[dir:data]]/logs/<date>.log''   | [[server:Terminal]] Server user activity |
| ''[[dir:data]]/logs/<date>.lol''   | [[server:Terminal]] Server user statistics upon log-off |
| ''[[dir:data]]/logs/FS<date>.log'' | [[server:FTP]] Server activity from [[sbbsctrl]], optional |
| ''[[dir:data]]/logs/MS<date>.log'' | [[server:Mail]] Server activity from [[sbbsctrl]], optional |

The ''*.log'' files without a date in their filename support automatic and configurable rotation (e.g. via [[util:SCFG]]->System->Advanced->Maximum Log File Size and [[util:echocfg]]->Global Settings->Maximum Log File Size).
