<H1>The Commandlog</H1>
<P>
The commandlog is a file where all communication with clients
having user or manager privilege is logged. This log allows to retrace each
step of an experiment. This log is normally configured in the startup
file or can be
configured by the instrument manager. There exists a special command,
commandlog, which allows to control this log file.
<DL>
<DT>commandlog new <i>filename</i>
<DD>starts a new commandlog writing to filename. Any prior files will be
closed. The log file can be found
in the directory specified by the ServerOption LogFileDir. Usually this is
the log directory.
<DT>commandlog
<DD>displays the status of the commandlog.
<DT>commandlog close
<DD>closes the commandlog file.
<DT>commandlog auto
<DD>Switches automatic log file creation on. This is normally switched on.
Log files are written to the log directory of the instrument account. There
are time stamps any hour in that file and there is a new file any 24 hours.
<DT>commandlog tail <i>[n]</i>
<DD>prints the last n entries made into the command log. n is optional and defaults to 20. Up to 1000 lines are held in an internal buffer for this command.
</DL>
It is now possible to have a script executed whenever a new log file is
started. In order to make this work a ServerOption with the name logstartfile
must exist in the instrument configuration file. The value of this option
must be the full path name of the file to execute.
