[rrd-users] Re: Maximum Argument Length?

[Cliff Daniel]

Thanks for the quick response.  I'm continously updating these indivdual
RRDs every 5 minutes.  Rather than having to add another rrd for Global/
Region/Market views I just chose to add the values from their respective
RRDs.  This potentially can get to be a large amount of arguments.  Would
you recommend going ahead like this or start creating their own RRD now
and updating with the rest.  These are GAUGE type RRDs so I don't run the
risk of Counter wraps.  With 400 DEFs it's only taking 2-4 seconds to
generate the gif so right now it's not a problem but I don't want to 
continue this route if in the future I might run into problems.o

One reason I'm inclinded to sum all the parts is because I will not lose
any historical data for a global view.  Is there a utility, or how
hard would to write one, that could exract the samples from x amount
of RRDs and store the sums of each sample into one RRD? 


Also, is there a way to get it to graph smoother lines on a step of
3600?  It's rather blocky otherwise?
