I have been looking at doing the same, but am not enough of a Perl wizard to do the scripts.  Would you be interested in sharing a sanitized version of your perl script?

A similar thing in the NT world; I have my main MRTG server that does the
web serving, graphs and data collection on the routers, while an old Pentium
server that I loaded Win2000 on is collecting data on NT servers through
performance monitor to a comma delimited file that RRD (through a perl
script) parses and saves the resultant rrd logs to a share on the main
server.  The main server can then use the logs on demand to create the
graphics.

I have 10 low end pentium rack mounted linux boxes polling devices.  These
weren't used anymore, but were perfect for this application.  Each mounts a
2 directories via nfs from high-end linux box, which is the mrtg web server.
Each polling box mounts a data directory, and also mounts a shared conf
directory.  I use rrdtool, so the polling devices only collect data and
update the log files.  The web server generates the html and graphs on the
fly using a cgi script.  There is one .conf per polled device (router1.conf
router2.conf, etc.).  Each linux box has one main conf file, i.e.
mrtg1.conf, mrtg2.conf, which has include statements for each device conf
which is polled by that machine.  Placing all the conf files in one
directory makes it easy (and fast) to use one cgi script to generate all the
graphs, on demand.

We have routers all over the world, with varying bandwidth and latency.  It
was only by using rrdtool, which allowed me to separate the polling from the
html generation, that I was able use cheap, relatively slow hardware and
still be able to poll everything in 5 minutes.

This setup is working very well so far.

Randall Fleischmann

Fellow mrtg users,

Does anyone out there in data land have more than one mrtg machine in their
enterprise?  I have a need to monitor about twice the number of devices I am
currently mornitoring, which will push the total devices I monitor to well
over
4,000.  With more than one target per device, I would bet I'm hitting more
than
8000 targets per 5 minute round.  Is there a way to integrate more than one
mrtg
machine into the mix, other than having one do just data collection and
graphing,
while the main one does the collecting, graphing, and web serving?

Thanks,
Paul
