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 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.


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

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


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

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 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.
