CDEF no graph

cc · Post by cc » Mon Mar 03, 2003 5:23 pm

Hi

I try to set up the CDEF with 3 interfaces , but no graph:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start="-86400" \
--title="Rindermarkt total traffic" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--vertical-label="Bytes Per Second" \
DEF:a="/srv/www/htdocs/cacti/rra/traf_192_168_111_3_16777219_in.rrd":traf_192_168_111_3_:AVERAGE \
DEF:b="/srv/www/htdocs/cacti/rra/traf_192_168_111_3_16777219_out.rrd":traf_192_168_111_3_:AVERAGE \
DEF:c="/srv/www/htdocs/cacti/rra/traf_192_168_111_4_16777219_in.rrd":traf_192_168_111_4_:AVERAGE \
DEF:d="/srv/www/htdocs/cacti/rra/traf_192_168_111_4_16777219_out.rrd":traf_192_168_111_4_:AVERAGE \
DEF:e="/srv/www/htdocs/cacti/rra/traf_192_168_111_2_2_in.rrd":traf_192_168_111_2_:AVERAGE \
DEF:f="/srv/www/htdocs/cacti/rra/traf_192_168_111_2_2_out.rrd":traf_192_168_111_2_:AVERAGE \
CDEF:cdefa=e,a,c,+,+,* \
CDEF:cdefb=f,b,d,+,+,* \
LINE1:cdefa#009F67:"total traffic in" \
LINE2:cdefb#0000FF:"total traffic out" \
AREA:e#:"" \
AREA:c#:"" \
AREA:a#:"" \
AREA:d#:"" \
AREA:b#:"" \
AREA:f#:""

Know somebody why ?

Regards
chris

Your CDEF function seems to be incorrect. You probably forgot of multiplying by 8. Right now you just add values from three interfaces and multiply it by nothing.

thanks, but still no graph:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start="-86400" \
--title="Rindermarkt total traffic" \
--rigid \
--base=1000 \

Hi

Chyba Pan jest jedynym w tom forum, ktory jest w stanie mi pomoc
i do tej pory rowniez Pan mi duzo pomogl.
Czy istnieje w ogole taka mozliwosc z 3 interface : 2 x Workstation
und 1 Printer zrobic sume i pkazac jako sume na jednym diagramie
i tylko jedna linia ?

Pozdrawiam
Christoph

It's nice to see this language here

however as long as we are talking on public forum I propose to use english so that the others can benefit as well.

I'm not sure how to add 3 series on one graph. This can be done using CDEF but I've never tried it before. You can however add three data series using STACK graphs. First select "Turn bytes into bits" CDEF function. Then mark your first data serie as AREA and two others as STACK. This will give you also a sum of the three data series on the graph.

Where can I select "Turn bytes into bits" ?
I can't find it.

It is on "Graph Items Configuration" page. Look for drop-down list called "CDEF Function".

Hi

I don't konow, how exactly You mean:
something, like this ?

Graph Items for: Rindermarkt total traffic Add

Well... this looks like mess

. I think hypotetical example should look like this:

Graph Item Data Source Name Graph Item Type Item Color Sequence Add
Item #1 traf_192_168_111_2_2_in AREA 00FF00 [Down], [Up] Remove
Item #2 traf_192_168_111_2_2_in: Current: GPRINT [Down], [Up] Remove
Item #3 traf_192_168_111_2_2_in: Average: GPRINT [Down], [Up] Remove
Item #4 traf_192_168_111_2_2_in: Maximum:<HR> GPRINT [Down], [Up] Remove
Item #5 traf_192_168_111_3_16777219_in STACK 00A348 [Down], [Up] Remove
Item #6 traf_192_168_111_3_16777219_in: Current: GPRINT [Down], [Up] Remove
Item #7 traf_192_168_111_3_16777219_in: Average: GPRINT [Down], [Up] Remove
Item #8 traf_192_168_111_3_16777219_in: Maximum:<HR> GPRINT [Down], [Up] Remove
Item #9 traf_192_168_111_4_16777219_in STACK 2175D9 [Down], [Up] Remove
Item #10 traf_192_168_111_4_16777219_in: Current: GPRINT [Down], [Up] Remove
Item #11 traf_192_168_111_4_16777219_in: Average: GPRINT [Down], [Up] Remove
Item #12 traf_192_168_111_4_16777219_in: Maximum:<HR> GPRINT [Down], [Up] Remove

Sorry... text file is not the best way for explaining how to set up the graph.

But what do you mean, I think,
is to show 3 interfaces each one separately on the graph.
I want to have the sum of these interfaces with only one line.

Regards
Christoph

bulek · Post by **bulek** » Sat Mar 15, 2003 4:29 pm

Yes... but each interface is on top of the previous one. As a result you see total traffic for all of them ( you can imagine a line on top of the last interface). However if you insist just on one line then I can't help you. This can be done with CDEF but I didn't try it before.

I need only one line and I know that can be done with CDEF funktion.
I know that's complicated.
If that doesn't work I do it with mrtg, it's much easier.
Anyway thanks for your help.
Where do you live in Poland ?
For me you are one of the best cacti gurus.

Thanks for nice words. For sure I don't feel myself as a guru. I just spent some time on this excellent software and try to offload Ian a bit by answering here to give him time required for 0.8 version progress.

Hi bulek

Who is Ian ?
Is he polish also ?

I assume you are "cc" user looking like "Hi" right now. Man... you really should read some docs before shooting all kind of questions on this board

.

Ian is cacti author and he for sure does not live in Poland.
