       logfetch	- Xymon	client data collector

       logfetch	[options] CONFIGFILE STATUSFILE

       logfetch	 is part of the	Xymon client. It is responsible	for collecting
       data from logfiles, and other file-related data,	which is then sent  to
       the Xymon server	for analysis.

       logfetch	 uses  a  configuration	file, which is automatically retrieved
       from the	Xymon server. There is no configuration	done locally. The con-
       figuration  file	 is  usually stored in the $XYMONHOME/tmp/logfetch.cfg
       file, but editing this file has no effect since it is  re-written  with
       data from the Xymon server each time the	client runs.

       logfetch	 stores	information about what parts of	the monitored logfiles
       have been processed already in the $XYMONHOME/tmp/logfetch.status file.
       This  file  is  an  internal  file  used	by logfetch, and should	not be
       edited. If deleted, it will be re-created automatically.

	      Enables debug mode. Note that when run by	the xymonclient, debug
	      output  may  be  written	into the client	data report, which can
	      cause false positives and	other  unintended  side	 effects.  Use
	      '=stderr'	to cause the output to be written to stderr instead.

	      The  client-local.cfg(5)	section	for this host, class, or OS is
	      automatically retrieved from the server  during  client  submis-
	      sion.   Logfetch	can be requested to execute arbitrary commands
	      to generate a list of log	files to examine dynamically, but this
	      can  present  a security risk in some environments. Set this op-
	      tion to prevent logfetch from executing requested	commands

       logfetch	needs read access to the logfiles it should  monitor.  If  you
       configure  monitoring  of  files	or directories through the "file:" and
       "dir:" entries in client-local.cfg(5) then  logfetch  will  require  at
       least  read-access  to  the directory where the file is located.	If you
       request checksum	calculation for	a file,	then it	must  be  readable  by
       the Xymon client	user.

       Do NOT install logfetch as suid-root. There is no way that logfetch can
       check whether the configuration file it uses has	been tampered with, so
       installing  logfetch  with suid-root privileges could allow an attacker
       to read any file	on the system by using	a  hand-crafted	 configuration
       file.  In fact, logfetch	will attempt to	remove its own suid-root setup
       if it detects that it has been installed	suid-root.

       DU     Command used to collect information about	the size  of  directo-
	      ries.   By  default, this	is the command du -k. If the local du-
	      command on the client does not recognize the  "-k"  option,  you
	      should set the DU	environment variable in	the $XYMONHOME/etc/xy-
	      monclient.cfg file to a command that does	report directory sizes
	      in kilobytes.
