Help printing SUM

Post by xefil »

Hello!

I've a problem creating a graph, ok, have to learn a little better how it works. Btw, I've create a graph with sum of different interfaces. I would like to print ad the end a line for incoming and outgoing traffic, like:

Total INCOMING: Current - Average - Max - Total
Total OUTGOING: Current - Average - Max - Total
Total INCOMING+OUTGOING

How can I print these vaules?

Ok, sorry, but using

Code: Select all

"COMMENT: Total In: |sum:auto:current:2:auto|"
the result is

Code: Select all

"COMMENT:"Total In\:  0 bytes\n"
How can I select that all traffic_in should be sum? (curr, average, total).

Oops, I missed the fact that you want IN/OUT to be printed instead of a grand total.
So let's try some CDEF magic.
Create two new CDEF that read cdef=SIMILAR_DATA_SOURCES_NODUPS and cdef=SIMILAR_DATA_SOURCES_NODUPY,-1,*. Add a new Graph Item, Data Source = "NTMAIL inbound" (this is to get the data source "traffic_in"), to your Graph Template and apply this new CDEF. Make it a black LINE1. Add legend with this cdef applied as well.
Repeat this step, this time with Data Source "NTMAIL outbound" (to get the reference to "traffic_out"), suing the second cdef. Apply Legend as well, this time using the first cdef.
Please post results. And please add the DEBUG output from Graph Management to verify.

and...

Code: Select all

Item # 14 	COMMENT: Total Out: |sum:auto:current:2:auto|<HR> 	COMMENT 	AVERAGE
Item # 15 	COMMENT: |date_time|<HR> 	COMMENT 	AVERAGE

The result of total _shuold_ be the total In/Out, right?
How then create total IN/OUT in the current moment?
Look to the total. One is the half, even if the traffic in and out is very similar, what's wrong?

I only would like to have a CURRENT IN (for all 3 interfaces) in MBit/s and the same for the OUTPUT.
Then, in addition, a TOTAL IN (AND OUT) for the timerange of the graph.
Last but not least, a TOTAL (in+out), that's it, seems difficult, I can't.
And these vaules are so strange :(

Simon

Thank's Simon

New Graph

Hi,

It drives me crazy :P
I post here an example of a NEW graph, easier, with only two interfaces, in hope to find a solution, step-by-step :)

LINE1:cdefcb#000000:"Total Out\: 5.56 GB\n"  \
COMMENT:"Total Traffic Throughput\:  99.23 GB"
As you can see, the "Total In" is equal to "VLAN10 Total IN" and "Total Out" is equal to "VLAN10 Total OUT".
The Total In should be "VLAN10 In + VLAN20 In"
The Total Out shold be "VLAN10 Out + VLAN20 Out"
But I think the RRDTool Command is right.....

Item21 and Item22 have a CDEF Function (cdef=SIMILAR_DATA_SOURCES_NODUPS,8,*)

Also I would like to have an output in this way:

Total IN Cur: 2,19M Avg: 4,44M Max: 12,54 Total: 47,14GB
the same for the output.

The last line should be correct, it means, TOTALIN + TOTALOUT.

Hope it's all, thanks :)

That's for the OUTBOUND stuff.
Let's stop here; grand total will be next step

Hi!

I've semplified the graph trying with only two interfaces, I'm near to the end solution.
My problems are always the same:
  • The "Sum Total In" (both IN interfaces) is equal to the sum of the "Vlan10 IN" single interface (the same for "Sum Total Out")
    The "Total Traffic Troughtout" is wrong. Should be Vlan10IN+Vlan20IN+Vlan10OUT+Vlan20OUT, but its the sum of Vlan10IN+Vlan20IN+Vlan10OUT+Vlan20OUT+Vlan10IN+Vlan10OUT again
    The alignment of the first line is wrong, ok, it's not so important ;)
Here the steps:

1. Created 2 CDEF as you said, but with a x8 to convert it into bits. (img attached).

2. Created Graph Item with Datasource "traffic_in" of VLAN10 with CDEF applied. It's a Black Line, shown into graph. The same for traffic_out, always choosing Vlan10, but this time I've applied the other CDEF (*-8). (img attached). Legend "Total In" and "Total Out" (items 22 + 27)

Well, this will get a bit complicated, but let's try.
Referring to the line Total In, I suppose, that you've selected the VLAN10 IN data source. To compute the "Amount of data tranferred for all Input data sources", you've added the COMMENT |sum,auto,current,2,auto|. In this case, the first current refers to the currently selected data source VLAN10 IN. So the total amount equals the total for VLAN10 IN. It would be fine to have sth like |sum,auto,similar_data_sources,2,auto| to cope with that. But unfortunately, there is no such variable (see here)

To conclude: You will have to leave the "Total Amount of Bytes transferred" off of "Total In" and "Total Out" lines.


Reinhard

BTB: Of course you may have a go to implement the missing feature :wink:

Ok, thank's Gandalf. I've removed tutal in + out.
Last thing, what about The "Total Traffic Troughtput"?
Should be Vlan10IN+Vlan20IN+Vlan10OUT+Vlan20OUT, but its the sum of Vlan10IN+Vlan20IN+Vlan10OUT+Vlan20OUT+Vlan10IN+Vlan10OUT again.

Last thing, what about The "Total Traffic Troughtput"?
Should be Vlan10IN+Vlan20IN+Vlan10OUT+Vlan20OUT, but its the sum of Vlan10IN+Vlan20IN+Vlan10OUT+Vlan20OUT+Vlan10IN+Vlan10OUT again.

I kind of feared that. The TOTAL stuff will include even the subtotals for In/Out. Please don't ask me, if this is intended behaviour. But you may ask (pm) The Witness.

This is a Tony Roman specialty. Please do not PM him. Try his e-mail. He does not like PM's.

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?
