4.3.7 Logging and Debugging

The directives described in this subsection provide basic logging capabilities.

Configuration: log-tag string ¶

Prefix syslog messages with this string. By default, the program name is used.

Configuration: log-facility string ¶

Sets the syslog facility to use. Allowed values are: ‘user’, ‘daemon’, ‘auth’, ‘authpriv’, ‘mail’, ‘cron’, ‘local0’ through ‘local7’ (case-insensitive), or a facility number.

Configuration: log-print-severity boolean ¶

Prefix diagnostics messages with a string identifying their severity.

Configuration: transcript boolean ¶

Controls the transcript of user sessions. If boolean is ‘true’, the transcript will be output to the logging channel. In the transcript, the lines received from client are prefixed with ‘C:’, while those sent in reply are marked with ‘S:’. Here is an excerpt from the transcript output:

S: 220 example.net dicod (dico 2.11.90) <mime.xversion>
  <1645.1212874507@example.net>
C: client "Kdict"
S: 250 ok
C: show db
S: 110 16 databases present
S: afr-deu "Afrikaans-German Freedict dictionary"
S: afr-eng "Afrikaans-English FreeDict Dictionary"
[...]
S: .
S: 250 ok

(The first line is split in two to fit in the printed page width.) This option produces lots of output and can significantly slow down the server. Use it only if you are debugging dicod or some remote client. Never use it in a production environment.
