I have well over 5000 targets currently, among close to 600 devices.

I use cfgmaker with templates to generate the configs.   I have a
database where I store the salient information (what subdirectory, what
are the snmp strings or V3 user information, what sort of device is it)
and another table that describes the particulars on a device (templates,
whether to include interfaces, what the ifref is supposed to be, snmp
timeouts).  Whenever I make a change, I run a script that generates
cfgmaker statements and a fresh mrtg.cfg file.  

My mrtg.cfg file has nothing but include statements.  I have a
"common.cfg" file with all of the things that need to be static -
workdir and mibs to be loaded, mainly - and then I have a separate cfg
file for every device, arranged in sub-directories.

I do use cron - that way I don't have to restart it every time I create
a revised config.
