MRTG like % on GPRINT

[raX]

This would have to be done with a CDEF. You could create a CDEF.

Create a new CDEF and add a new item to it. Check the "Use the current data source being used on the graph instead of a preset one." box and click "Save".

Add another item. Choose "Add a CDEF Function." and choose the '/' item. Click "Save".

Add another item. Choose "Add a Custom Entry." and type the maximum value in the box. Click "Save".

Now if you add a GPRINT graph item and choose this CDEF (and the data source to apply the math to), you should have a nice percentage to work with.

HRULE's and VRULE's are used to put static lines on the graph. For instance, if you add an HRULE and type '10' for the value, it would place a horizontal line on the graph at '10'. A VRULE is the same thing, but is time-based. Here is some more information:

(from Danny Bendersky)
"$time = `date -d "today 00:00" +%s`;
add to your graph "VRULE:$time......"

If you excecute the command you will get something like: 1016164800

But this number represent the 00:00 time for today, so tomorrow will be different."

I can't achieve to dşsplay my GPRINTs like MRTG Style (XX(%XX)
Anybody help me by telling step by step?
And Ian, why don't u think to add this style to graph template in next version?
I use cacti 0. 8.3a
Pleaseee...

Hi,

I have recently tried to represent the memory percentage for different routers in one template with a CDEF Function. For this I am using the following function:
cdef=CURRENT_DATA_SOURCE,CURRENT_GRAPH_MAXIMUM_VALUE,/,100,*

I have selected into DATA TEMPLATE that I will put manually the Upper Value for the graph, since not all the routers are having the same amount of memory.

Can u please confirm me that my formula is correct?
Second thing is that I am afraid that, by replacing CURRENT_GRAPH_MAXIMUM_VALUE, Cacti will use the default value given into data template, and not the real Upper Value which I will set by each new graph. Am I right .. if so, who can help me with a new SPECIAL DATA source script which will read for me the Upper Value which I set per each graph, and also info how to import it into cacti...


Thank you in advance for your time!

Hi again,

I found where I was mistaken. I was considering Uper Value that it is coming from Data Template, but now I see that it was taken from Graph.

My new question, if accepted , how can I pick Upper Value from Data Templates in Special Data Sources?

Am I on the right way now?

Thxs,
Dan

Hi All,

I'm trying to graph the % Error Rx in a wireless interface. I'm trying something like this:

Code: Select all

cdef=APG_Errors,/,(,APG_Frames,+,APG_Errors,),100,*

How can I use this CDEF in a expecific graph with two data_sources [total_errors and total_frames].

I have to add a GPRINT - CDEF for each data source on graph_template???

Tks
