[rrd-users] COUNTER32 and Summarization Graph

[Felici Simone]

Hello to all!

I need a little help.
I've a script collecting many-many values (COUNTER32) on Cisco devices and
until here it's all ok!
Every line is stored into a single rrd file, because there are daily new
lines configured and the script create new rrd files if needed.
If I try to generate a graph for a single file all works well. I need a
Summarization Graph to display the total traffic of all lines.
I've also created a script with CDEF commands make a sum of all lines and
create a single graph. All works well until today. The lines of one device
are groved up a lot and I've received the following error:

"/bin/rrdtool: Argument list too long"

There are 248 lines, 248 values into one value (CDEF SUM). It's possible
I've reached the maximum number of values to sum?

If it's true, can someone help me to find a way to SUM all lines into one?
The COUNTER32 values are "strange" to sum together before are stored into
one single rrd file.
I could collect all values, but dont know how sum the values together and
store all into a single rrd file instead of sum all these values with CDEF
commands.

Any idea?

Thank's a lot to all!
