Can you please provide the error, or the debug output from the Preview tab with debug enabled?

@yingbaiibm, second piece that we need is a screen capture of how you went about creating the aggregate. Nee to know what you included and skipped and the various settings that drove this error.

It's just simple aggregate graph creation, do not need to change anything.
After click save button, the RRDtools error will exist.
No error log in cacti.log
NO error in /var/log/httpd/error_log

This is completely understandable as you skipped all items. I guess maybe the right thing to do would be to block the save button unless one item was not marked to skip. Easy enough to force fix. It's a minor issue though.

[cigamit]

Okay, until you click at least one 'total' item, you can no longer save. That should cover this issue well.
