[SOLVED] Why in equals out ?

surleau · Post by **surleau** » Tue Mar 04, 2008 8:48 am

Hi,

I'm in front of a graph I don't understand : it's a traffic graph where all inbound traffic strictly equals outbound traffic. I do know that it's not what's happening on the device, so I can't trust the system until I solve this. Could someone help please ?

Cacti 0.8.6j, running on MandrivaLinux

How are you grabbing the data?
If you are using SNMP, what version?

If you know the values are different, how are you determining that?

You could always write a script, import it in to Cacti and use the script to call the values that you trust.

Cacti only reports the values it is given, so it's not like it is making up numbers.

Hi

can you go to graph management, select your graph, and check that in and out are selected (and not in and in) ?

Great ! Thanks a lot.

Did I do someting wrong, or is it a referenced bug ? I just created the device an created the graph for the host, that's all.

I also have this "bug" from times to times

So, post your graph debug for the graph in question. Also, some interfaces are behave this way. Not sure why, typically on routers.

Is this what you ask for ? :

RRDTool Command:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-60 \
--title="SM1 - Traffic - Gi1/0/1 - SWR101(66)D-LET" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="bits per second" \
--slope-mode \
DEF:a="/var/lib/cacti/sm1_traffic_in_10.rrd":traffic_in:AVERAGE \
CDEF:cdefa=a,8,* \
AREA:cdefa#00CF00:"Inbound" \
GPRINT:cdefa:LAST:"Current\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdefa:MAX:"Maximum\:%8.2lf %s\n" \

GPRINT:cdefa:LAST:"Current\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdefa:MAX:"Maximum\:%8.2lf %s"

RRDTool Says:

OK

Well as you can see from the graph command, it's only pulling your Traffic input values and displaying for both in/out.

In graph management, find that graph. Is the input and output data sources different?

Yup, the template is jacked. If recreating the graph does not fix it, you need to look at your templates. It is conceivable that you may have found a bug too. I do doupt it though.

Well, I corrected the graphs, and now they work fine. Thanks for that.
Then I tried to repeat the initial steps, to see if I could see the problem again. The new graphs appear correctly now, so I don't know how it came.
