I remember that thread now, but I didn't understand quite what was going on. I've recently been trying to solve a different problem related to the same bit of code.
I've had to make an touch ifsum.rrd and voila, the graph will be display
Is that an bug ?
Probably not really a bug. It's just that the code that generates the trends page was not (it seems) designed to handle graphs where the graph name doesn't match the RRD filename. It probably needs enhancements to incorporate this as a feature.
The code also looks at FNPATTERN in the graph definition to tell the code which filename to look at, and while it is probably not intended for use with fixed filenames like you're using, it might still work, without having to create a dummy file.
