Graph too big for Cacti to generate a graph image?

[rvt]

Hi All,

I have a graph with 220 data sources that it's being displayed. When I bring up the Debug there is no error reported. If I copy and paste the RRD command line that the debug shows me into a terminal and run it then an image is generated. It seems to be like I'm hitting some limit in Cacti/PHP but I don't see any errors in the cacti.log or Apache's error.log file.

I'm running PHP with a max memory setting of 1GB.

Any ideas?

Here's my RRD output, http://pastebin.com/q3HTvy20. I couldn't paste it into this post as the forum software complains it's too large.

Thanks.

At least on windows, there is a limit of how many characters you can pass for a command -- often users reach this for large mutli-datasource graphs. I'd assume you've reached the similar limitation for Linux.

Are there any work arounds?

I can get the image to be generated on the command line by putting the rrdtool command into a bash script and running it so doesn't seem to be a shell limitation.
