I think it most definitely needs a little documentation.  It's pretty simple I think to get started once you see how it's done. =)

But yes, as for calling functions in RRDTool, you can just use the documentation on the RRDTool homepage.  From the script side, it's almost like a wrapper around the RRDTool commands, with the catch of formatting each RRDTool command option as a seperate function argument.

The errors are also the same generated by RRDTool.

But I also have to agree, I much prefer using Python with my RRDTool problems. 

Let me know if I can help more.

Yes, well, I have practically no experience in Perl :)

Thank you!

Aaah, this is probably where I messed it up...

So it essentially works like calling the shell rrdtool..?
Ok, Thanks!

I did some basic testing with os.system() but I think I'll rewrite those
parts :)

But considering how great a language Python is and how great RRDTool
is with graphing, I still believe that python-rrdtool deserves clearer
documentation and then publicity :)
