GRAPHING ONLY IN OUTBOUND DIRECTION

[SammyKim]

Hello,

I have a problem with one of my graphs graphing in only one direction-OUTBOUND, but not graphing in the INBOUND direction. Anybody knows how to solve this? Any help is appreciated.

Look at the data being fed into the RRD file (use the graph debug options). If that does not hold the data you are expecting, use SNMPWALK to check that the values are actually being returned by the device in question.

Look on the device, what is the actual traffic on the interface. Is there really two way traffic on the interface or is the traffic one way? If the traffic is two way what is the value?

[SammyKim]

Hi. There is 2 way traffic. The device on the other end of the connection indicates there is traffic in both inbound and outbound directions. I am doing a peak of 9.7 Gig on the other side in outbound direction, but none is seen in the inbound direction of the device in question.

[RustedKnight]

can you provide a screen shot of the graph for both sides of the link? Also, do you know how to check the max value of the rrd file?

[SammyKim]

Hi. The graphs are attached. Actually, I do not know how to check max RRD value. Open to any guidance. Thanks.

[SammyKim]

Correctly graphing...

When you are under Console -> Management -> Graphs -> Edit Graph there is a Turn On Graph Debug option top right. That will give you a whole set of information.

Hi. Below is the output from graph debug.

RRDTool Says:
OK

[netniV]

OK so the definition looks OK. What is in the actual data? Use the Cog icon next to the displayed graph on the graphs tab.

[SammyKim]

Hi. Do you mean the 'spanner' icon?

[netniV]

Ah, did I miss that you are running an older version of Cacti?

[SammyKim]

I am using Version 0.8.7i

[SammyKim]

From the 'spanner' icon, I get the below output...

Ah, if you are saying that it's a spanner, then you must be running a pre-1.x version of Cacti.

That means you would have to manually look at the data, etc. I'm not even sure if that version has device debugging which would give you more information as it's polling.
