[mrtg] MRTG Daemon at Startup with hundreds of configs

[Adamiec, Larry]

This may help get you started.  Put all your configs in one directory and the place this code in your startup script.  Edit it to meet your needs.   
 
I have NOT tested this code.  Use at your risk.
 
************ Start of Code ********************
CONFIG_DIR = "/etc/mrtg/configs"
start() 
{ 
     echo -n $"Enabling MRTG: "
     rm -f ${LOCKFILE} 2> /dev/null
 
     cd CONFIG_DIR
 
     for i in `ls`
     do
       env LANG=C ${MRTG} --pid-file=${PIDFILE} --lock-file=${LOCKFILE} ${OPTIONS} ${i}
     done
}
 
************ End of Code ********************

	Subject: [mrtg] MRTG Daemon at Startup with hundreds of configs
	
	
	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....
	
	
	
	#!/bin/bash
	#
	# mrtg          This shell script starts mrtg
	#
	# Author:       Stefan SF 
	#
	# chkconfig:    345 90 35

	# processname:  mrtg
	
	# config:       /etc/mrtg/mrtg.conf
