How much DS per IP under v.1.2.30(win32) ?

[ThomasJ-4]

Hello everyone,

i got stuck while retrieving 3 Ds of one device. Everything worked fine with
2 Ds, but i can't get it to work with 3 Ds. The *.rrd remains with *UNKNOWN*
Data.
I'm pretty confident to have set up propper config and propper "manually"
the *.rrd

So i guess that there might be a limitation in the 1.2.30 (win32)
distribution.

Am i right, or am I missing something...


For completeness here is my config.cfg:

WorkDir: C:\xampp
RunAsDaemon: yes
EnableIPv6: no

LogFormat: rrdtool
PathAdd: C:\xampp

HtmlDir: C:\xampp\html
#ImageDir C:\xampp\html\graph
IconDir: C:\MRTG\Icons

Interval: 0:05

MaxBytes[_]: 1600
Options[_]: gauge

Target[test]: ...1.3.0&...4.14.0&...4.16.0:public@...
title[test]: test


...and this is what ends up in the *.rrd

test.rrd
 
filename = "test.rrd"
rrd_version = "0003"
step = 5
last_update = 1245881858
ds[Tx].type = "GAUGE"
ds[Tx].minimal_heartbeat = 600
ds[Tx].min = NaN
ds[Tx].max = NaN
ds[Tx].last_ds = "UNKN"
ds[Tx].value = 0.0000000000e+000
ds[Tx].unknown_sec = 3
ds[Sig].type = "GAUGE"
ds[Sig].minimal_heartbeat = 600
ds[Sig].min = NaN
ds[Sig].max = NaN
ds[Sig].last_ds = "UNKN"
ds[Sig].value = 0.0000000000e+000
ds[Sig].unknown_sec = 3
ds[Rx].type = "GAUGE"
ds[Rx].minimal_heartbeat = 600
ds[Rx].min = NaN
ds[Rx].max = NaN
ds[Rx].last_ds = "UNKN"
ds[Rx].value = 0.0000000000e+000
ds[Rx].unknown_sec = 3
rra[0].cf = "AVERAGE"
rra[0].rows = 1024
rra[0].cur_row = 922
rra[0].pdp_per_row = 1
rra[0].xff = 5.0000000000e-001
rra[0].cdp_prep[0].value = NaN
rra[0].cdp_prep[0].unknown_datapoints = 0
rra[0].cdp_prep[1].value = NaN
rra[0].cdp_prep[1].unknown_datapoints = 0
rra[0].cdp_prep[2].value = NaN
rra[0].cdp_prep[2].unknown_datapoints = 0

                          Tx                   Sig                Rx
1245881900: -1.#IND000000e+000 -1.#IND000000e+000 -1.#IND000000e+000

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@...
Target[test]: oid3&oid3:public@...

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:
http://oss.oetiker.ch/rrdtool/prog/index.en.html

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

Cacti is a bit like mrtg on steroids.

Hi David, thx+ for your hinds so far.

One last question, which info i might had also overread.

In case i'm using two targets to gather my 3 Ds's, can i combine their
informations in one graph ?

Yes, but only if you're using Routers2 as your frontend for MRTG/RRD or if you write your own code to do it.  This should really be in the MRTG mailing list, you know, not the RRD one...
