====== syslog (UNIX) ======

Synchronet for *nix-like OSes can send its server and services output to your system's ''[[wp>syslog]]'' facility (e.g. ''rsyslogd'' on Debian Linux). When running ''sbbs'' as a daemon, syslog-output is automatically enabled. When running ''sbbs'' interactively (not daemonized), syslog output can be enabled by passing the ''syslog'' command-line option to ''sbbs'':

  $ sbbs syslog

===== Configuring ===== 

The syslog functionality is configurable via the ''LogFacility'' (default: ''U'') and ''LogIdent'' (default: ''synchronet'') values of the ''[[config:nix|[UNIX]]]'' section of your ''[[dir:ctrl]]/[[config:sbbs.ini]]'' file.

You can further configure your syslog output (e.g. directories and filenames) through the setup of your system's syslog facility (e.g. via the ''/etc/rsyslogd.conf'' file on Debian Linux).

===== Monitoring =====
The ''syslog'' output of the Synchronet daemon will usually go to a file in your ''/var/log'' directory. You can monitor real-time changes to this file with the ''tail -f'' command.
  $ tail -f /var/log/sbbs.log

If you're using **systemd** to start and control ''sbbs'', you can use ''journalctl'' to monitor the log (with colorized log lines) in real-time:
  $ journalctl --follow -u sbbs

Another option for systemd systems is to use ''systemctl'' together with ''watch'' to monitor both the service status and log output together in real-time:
  $ sudo watch systemctl status sbbs
  
An alternative tool to actively monitor log files is the ''lnav'' utility:

  $ sudo lnav /var/log/logfile
