Aggregate bandwidth and total bandwidth

[apex333]

I am aggregating several interfaces for a sum of bits in/out. I would also like a "GPrint", showing "Total throughput" of Bits in/out.

Is there a way to apply the |sum:auto:current:2:auto| code to sum the total throughput of all interfaces plotted?

Thanks,
Richard

Apex, I'm doing the same thing to see how much data we spew out onto a particular WAN. Change your string to the following and I think you'll be set.

Code: Select all

|sum:auto:total:2:auto|

It did the job, however this can't possibly be true for both in/out...
How do you come up with code for summing up?

Hmm... I may have misled you a little. I forgot, but the graph that I was doing mine on was only a total of all traffic_in from many DS. I wasn't doing traffic_out on that one.

I just looked, and the "total" keyword sums up the totals of all data sources in the chart... So you're looking at the total amount of data both sent and received, I believe.

You may have to settle for that and rename your field "Total data sent/rec'd" because the docs I was referencing show no other choices:

(current|total) You can choose to calculate the summation based on the current data source or a total of all data sources used on the graph. The only valid values for this field are 'current' and 'total'.

This was from the Cacti docs here: http://www.cacti.net/downloads/docs/htm ... _VARIABLES

Other choice I can think of off-hand would be to break it into two graphs... One sent, the other received.

Hello guys, i have the same kind of problem :



I've tried the solutions proposed above without success. If someone has an idea...

Thanks in advance

edit : i forgot to precise i'm running freeBSD 5.3, net-snmp-5.2.1.2, rrdtool-1.2.10, cacti-0.8.6f

LB, can you elaborate a little on what is wrong with yours? It looks like you are just charting one interface... The numbers all look reasonable to me... ?

Yes, but i can't get total amount incoming, although it works for outgoing traffic In the Graph template i get the same warning as apex333 showed at the beginning of the thread.

Turning on debuggning just say that it's ok for rddtool.

I've just noticed that :

GPRINTLAST:" Current\:%8.2lf %s" \
GPRINTAVERAGE:"Average\:%8.2lf %s" \
GPRINTMAX:"Maximum\:%8.2lf %s" \
COMMENT:"Total In\: 715.95 MB\n" \
LINE1:b#002A97:"Outbound" \
GPRINTLAST:"Current\:%8.2lf %s" \
GPRINTAVERAGE:"Average\:%8.2lf %s" \
GPRINTMAX:"Maximum\:%8.2lf %s" \
COMMENT:"Total Out\: 668.81 MB"

So that's just a problem making the png, i think.

[jas0420]

Sorry, I completely missed that the first time I looked. I was looking at the number directly below it.

What has happened on yours is that it scrolled off the right-hand edge of your png file. You need to either shorten your words (change "current" to "now", "average" to "avg", etc) to make the whole line shorter, or, put in a hard return further up in your graph items (like on the "Average" graph item... if you go into the details of that line, the bottom option will be to insert a hard return... check that box)

buddah,
Try going into your graph template and make the graph longer or edit the "inbound" to "in", the Average to "avg", so you can fit more per line.

Yep, i was surprised that it cut correctly the outgoing line and not the incoming line. Anyway, it looks really better like that :



Thanks !

Hi Richard,
I have gone through jason steps in graphing two interfaces but was reporting wrongly. the result was reporting the first interface and not the second interface.

Please assist
