"Interface - Traffic" graph template problem

jberanek · Post by **jberanek** » Thu Apr 02, 2009 10:17 am

Using Cacti 0.8.7d (was until today using 0.8.7b, but the issue wasn't fixed by my upgrade)

Recently my "Interface - Traffic" graph template has become incorrectly formatted, and no matter what I do to it I can't fix it. Maybe someone here can point me in the right direction.

I attach a few files, the first of which, graph.png, shows the problem. The "Outbound" legend item appears on the same line as the "Inbound" one, disregarding the order shown in the template. It also appears before the "Total In:" comment.

The second file, graph_template.png, shows the template.

The final information I can provide, is the rrdtool command. This clearly shows the error (the graph items are in the wrong order), but I don't know how to go about correcting it...

Many thanks for any help, this is driving me nuts.

Please check the HR checkbox of the last graph item and verify again

Thanks for your reply - that doesn't seem to change anything visually.

This is very strange and did not happen to me yet. So please verify again from Graph management that this graph is still related to that very Graph Template you're changing. Or change any other entry to verify that the change is propagated to the graph

Attached another screenshot showing the graph setup (verifying the graph template chosen) and the graph debug.

Well, the templates looks fine. The graph is weird but matches the (broken) rrdtool graph command. So the question is: why is the template correct but the graph broken?

Did you recently change the template?
Please export the template and post it here for me to verify

I don't remember changing it and then seeing it broken - it could be I did though...

Template attached - it's different from the default template because it's got "total bandwidth" figures like the default "Interface - Traffic (bits/sec, Total Bandwidth)" template. I added these because I kept creating graphs with the "Interface - Traffic (bits/sec)" template and got graphs without the total bandwidth, which I wanted.

(I didn't add dependencies to the export for brevity - I can add these if you like)

Hmm, that's interesting - if I do change one graph to the "Interface - Traffic (bits/sec, Total Bandwidth)" template, the display is fixed...

Attached is that template.

A diff of these 2 files doesn't show much significant change to me - only a few sequence numbers different (in the "outbound" figures)...

Hmm, one further piece of information.

If I change a graph to the "total bandwidth" template, and then change it straight back to the "normal" one, the graphs is _also_ fixed!

John.

OK, last post this evening, honest!

After this the graphs all went odd, as the attached image shows.

This appears to be to do with inappropriate data sources being used in the rrdtool command:

Code: Select all

CDEF:cdefa=a,8,* \

GPRINT:cdefa:LAST:" Curr\:%8.2lf%s"  \
GPRINT:cdefa:AVERAGE:"Avg\:%8.2lf%s"  \
GPRINT:cdefa:MAX:"Max\:%8.2lf%s"  \

LINE1:cdefa#002A97FF:"Outbound"  \

GPRINT:cdefg:AVERAGE:"Avg\:%8.2lf%s"  \
GPRINT:cdefg:MAX:"Max\:%8.2lf%s"  \
COMMENT:"Total Out\: 2.54 GB\n"

Note how both the green AREA and the blue LINE1 use "cdefa"...

What was the base template used? Did you copy a base template or create this one from scratch.

Indeed, the sequence number issue is what I was looking for.

I'm pretty sure I took the standard "Interface - Traffic (bits/sec)" graph template, and then added the extra bits from the "Interface - Traffic (bits/sec, Total Bandwidth)" template by hand.

That would be the required procedure. When changing the related graph template for those graphs back and forth, does this give you "good" graphs?

Not really - many of my graphs have now messed up "Inbound Data Source" and "Outbound Data Source" - typically both showing the same data source, but I've also just seen one where the data sources were reversed, but the graph looked like both data sources were actually the same.

I'm a bit baffled, and dispirited that I might have to go and manually edit 331 graphs!
