NAME

       logfetch - Xymon client data collector

SYNOPSIS

       logfetch [options] 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 $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.

OPTIONS

       --debug[=stderr]
              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.

       --noexec
              The client-local.cfg(5) section for this host, class, or OS is automatically  retrieved  from  the
              server  during  client  submission.   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 option to prevent logfetch from executing requested commands

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-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.

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 $XYMONHOME/etc/xymonclient.cfg file to a command
              that does report directory sizes in kilobytes.
