Agreggating router interfaces into one graph - plus total

[UKS-Gavin]

An excellent guide and one that worked well.

Really nice one.
You've already seen those graphs showing Outbound on the negative y-axis? This may improve reading those graphs. To get this effect, apply a CDEF=CURRENT_DATA_SOURCE,-1,* (Make Negative) to all outbound LINEx/AREA/STACK items (not to the LEGEND items!) of the Graph Template

I have create a graph without template. (for counting active users from 4 servers)
So it is not a datasource. Is it possible to set a threshold on the total?

Thanks

That's not a good idea if you want to reuse this. But you may copy the Graph Template and create a Graph Template out of it, so no harm done ...

That's more a question of the thold plugin. I'm not really an expert on this, so please post there

I can quite easily see a dropdown from the Data Sources screen, where you would follow the following process:

Code: Select all

1) Select all the data sources that you want aggregate graph fo
2) From the Drop Down, Select "Create Aggregate Graph"
3) Press "Go"
4) In the Code do the following
    a) Verify all Data Sources are of the same type
    b) Prompt the user for "which" data sources will be used in consolidated graph.
    c) Provide Type of Line, or Stack
    d) Name the Graph
    e) Name the Resulting Legends
    f) Pick Gprint types (MAX, MIN, AVG, CUR)
    g) Pick colors for each Data Source
    h) Create graph using Cacti internal functions.
5) Be well and prosper.

Only problem is that, unfortunately, there is not time enough in the day for us to get to this as well as cover the boards and work our various development efforts.

Is there an official feature request for this anywhere? This would be extremely useful. It would also allow us to filter on all data sources for a particular host and then effectively create an aggregate graph for an entire host.

I'm currently thinking about a plugin for such a problem. But forum comes first

hi,

its possible to get one graph for 95% percentile, sum traffic in and out?

i have make some graphs for this, but i only get displayes data from my last server.

please help

Please see http://www.cacti.net/downloads/docs/htm ... _VARIABLES

Im having a little problem. Scale on negative y-axis seems to be rediculously small compared to positive y-axis. Lets say that I have incoming traffic aggregate of 2x and outgoing of x. Now size of my positive axis is like 3cm and negative like 0,1cm.

Any advices?

[gandalf]

Yes, but I need the whole rrdtool graph statement for your current graph (click the wrench to get it) along with a screenshot of the graph

Solved the problem myself. One should use -8 not -1, if using bits instead of bytes everywhere else. Because you can not invert y-axis AND convert bytes to bits, so you have to do this in the same CDEF.

Which then looks as follows:

Item #1 Special Data Source: CURRENT_DATA_SOURCE
Item #2 Custom String: -8
Item #3 Operator: *

Please find a new approach on aggregating graphs via "Aggregate Plugin". Please comment.

I have made it work, but i have problem.
I don't want to graph Data in Mbit and Kbit, i want to graph Ds 0-7 E1 interfaces on AS5400 and active calls on them
Help?

[Betmen]

I have figured it out, just create CDEF
Special Data Source: CURRENT_DATA_SOURCE and everything works nice
