NAME

       logfetch - Xymon client data collector

SYNOPSIS

       logfetch CONFIGFILE STATUSFILE

DESCRIPTION

       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
       configuration  file is usually stored in the $BBHOME/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 $BBHOME/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.

SECURITY

       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-acces 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  con-
       figuration file. In fact, logfetch will attempt to remove its own suid-root setup if it detects that it has been installed suid-root.

ENVIRONMENT VARIABLES

       DU     Command  used  to collect information about the size of directories.  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  $BBHOME/etc/hobbitclient.cfg
	      file to a command that does report directory sizes in kilobytes.
