[mrtg] MRTG Daemon at Startup with hundreds of configs

[Mersberger, Robert]

I run a cron job that runs the following script.
[root at mrtg ~]# cat mrtg_run
#! /bin/bash
 
for fn in /etc/mrtg/*.cfg; do
        env LANG=C /usr/bin/mrtg "$fn" &
done
 
[root at mrtg ~]# 
 
Job runs ever 5 minutes and maintenance only needs to be done to the
config files in the /etc/mrtg directory. if you don't want a config to
be processes change the file type to something other than .cfg.
 
Hope this is what you were looking for.

What about a few 'master config'  files only containing some basic setup
and 'include: ..' statements to all your existing config files? 
In this way you only need to start your master config files.

	Hi there,
	
	I'm looking at a project to switch a server that is using MRTG
to monitor hundreds of devices over to running MRTG in daemon mode, for
efficiency. As one could infer, there are hundreds of config files to go
along with those hundreds of devices. Since MRTG has to be started once
for each config, I'm trying to develop a Linux startup script that will
execute all of the configs. I will copy/paste the startup script I'm
currently working with. Does anyone have any idea how to change this to
make it start up all of the configs? It may be an easy answer, but I'm
very fresh on shell scripting and have spent hours searching for this
info, to no avail. Please help! 
	
	Thanks in advance for any advice or help you may provide...here
is the startup script I found....
