[rrd-users] How much DS per IP under v.1.2.30(win32) ?

[David Thornton]

mrtg is designed to collect data in pairs, as in OctetsIn and
OctetsOut. Remember MRTG was originally conceived to collect stats on
interfaces.

It's possibly to create rrds that contain many many more DSs however
MRTG will only work with rrds that store two DSs

You have at least two options:

1. user another mrtg target and put the third oid in twice (mrtg will
only collect it once).

some thing like this:
Target[test]: oid1&oid2:public at 192.168.56.101
Target[test]: oid3&oid3:public at 192.168.56.101

2. use a different package than mrtg to update your rrds ( in my
opinion that'st he wrong way to go as mrtg is quite wonderful , fast
and feature rich)

You could write a reasonably simple perl script that does the update
(using RRDs). Or depending on how complicated or large your setup will
be, you could go for something like cacti which "simplifies" working
with more complicated data sets.

more on making you own scripts that work with rrd files directly:

more on cacti ( [A] "complete network graphing solution designed to
harness the power of RRDTool's data storage and graphing
functionality." )

Cacti is a bit like mrtg on steroids.
