 |
|
Hi,
Some gprint data on a graph I attached look strange because it's in bytes not bits. Sorry I attached a new one where I turned it to bits and it's ok. But i still need an answer why the sum not work?
If you see the max in/out it's GT 60Mbits but the graph still under 100Mbits! Why?
Inbound Host1 is an AREA type Inbound Host2 is STACK type. Is it wrong or the graph turned into a negative value?

The Max for In-Host1 and In-Host1 didnt happen at the same time ?
The Graph looks rights for the current values - total of about 87ish and the graph is just under the 90 Mb/s mark.

Yes, you're right Deano! The max didnt happen at the same time! It's clear now!

Hi,
I made this graph by hand so I have no temlpate. (In 0.8.3 no template but now I move to 0.8.5a and I will export 4U)
Until here is the graph edit snapshot

Hi guys, I'm trying to import the template from above and I'm getting errors.
I'm not sure what's going on.
--
Graph Template
[success] Sum of 2 Graphs [update]
+ Unmet Dependency: (Data Template Item)
+ Found Dependency: (CDEF) Turn Bytes into Bits
+ Found Dependency: (GPRINT Preset) Normal
+ Unmet Dependency: (Data Template Item)
--
any suggestions?

How to graph the diffrence between in and out and sumation of ...
1. console -> Graph Management -> CDEFs -> Add
name: make zero
cdef=CURRENT_DATA_SOURCE,0,*
name:diff
cdef=8,b,a,-,*

NOTE: because Item5 is LINE and Item4 is Area we must create #5 before #6
Now in "Graph Item Inputs" we must add two item manually and adjust "Associated Graph Items" for each one
and thire name.

3. console -> Graph Management -> Add

If you are a new user of Cacti, the easiest way to create graphs with a sum already on them is to:
1) Go to "Polling Hosts" in Cacti.
2) Either add a new host or edit a host that contains traffic you want to sum up.
3) Make sure you have the "SNMP - Interface Statistics" data query selected by selecting "SNMP - Interface Statistics" under "Associated Data Query" and clicking "Add".
4) Place a checkbox next to the interfaces you want to create summation graphs for.
5) Click on the dropdown that says "In/Out Bits" and select "In/Out Bytes with Total Bandwidth".
6) Once you click save, you should have some graphs that contain summation data on them  .
The following set of instructions assumes that you want to sum up traffic, which is most often the case. You are not limited to this however. The instructions provided in the manual should work for any type of data.

The url quoted does not exist anymore, And this walkthrough does not match 0.8.6b
I'd like to make a graph that has data for two interfaces on a single graph, Index 9 and Index 24 on one of my routers where it would show the combined traffic on the two interfaces.
Is this what the document quoted would have described?

This is such a widely requested feature that I am surprised there isn't more documentation on this. I am still trying to figure out the easiest way to do this, other than manually making graph templates based on the # of interfaces/data sources I want to aggregate.
We need a detailed HOWTO on creating aggregate graphs..

Agree. Perhaps someone could contribute a guide to the new documentation project?
I also guess the authors have on the TODO list for Cacti a more elegant and easier way to do this.

If yes, then it's ok ... it's working.
But what i really want, is the possibility to put tables, with the summary of the trafic in numbers...
I have a nice PHP script, that can summarize the trafic. You can choose to see the results for a period of days, or for a whole mounth, also a year if you collected the data... Really, i will appreciate if something like that can be done in Cacti, because actually i continue to use MRTG, only for that feature ....
I will be more then happy to share this script, if someone think that it can be used / converted to and for Cacti

I`ve been looking into this myself aswell.
Currently it seems cacti makes the sum just fine in the graphs.
At the moment its a bit annoying to go through all the graphs to report the the total sum of a port/switch.
Feel free to post the script .. i might have some spare time to make a patch for it.
