## 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 $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.

## 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 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.

## FILES
