[mrtg] Re: Total Traffic per Switch

[Thierry Silly]

Hello,

     First, thanks for your help.

1- I know that I only do an estimation of my backplane traffic, It's just for me to get an idea,
     and to check if the load is not too high telling me that I need to buy another switch.
      In my case it's quite specific as I know that about 90% of my traffic goes throw the RSM.

2- I'm using RRDtool too for other things. In fact, on the other hand of my mrtg stats, I use rrdtool to generate a database,
     with all my ports traffic and to only graph the datas when I need to monitor 1 port. (just a little new
     challenge for me, I know some tools are doing that).
     my problem is that I don't know if I can create a rrd file with about 300 DS in it. Does someone know  if it is possible ?
     How can I create such a rrd file  in another way than typing 300 time DS:...:...:...:...: ?



Thanks a lot,
BRgds,
Thierry

I think this only works when you indeed pass all traffic through
your RSM.  Local traffic (same subnet) doesn't use the RSM and
if the in and out ports are on the same module it doesn't even
use the backplane.

If you'd use RRDtool as back end, you're able to write a script that
uses all of the ports as input and add their traffic together. AFAIK
there is no counter on the switch (but I may be wrong!)
