[rrd-users] rrdtool or equivalent on an asp.net hosted server

Yes, the binary format is different as the library was built without looking
at rrdtool's source code (in order to give it a different licence, ie LGPL).
Nevertheless, it should be pretty efficient.

I can't remember about that bug you mention - but isn't it the expected
behavior? Or should there be any kind of right-border detection?

So, I did some tests during the weekend to implement rrdshar in my

This is the result:  http://otio.se/~jonas/rrd/ <http://otio.se/~jonas/rrd/>

It wasn't easy to get it to work as I wanted it without any documentation on
the methods in the library what so ever. But finally I got something that is
usable up and running.

One thing I noticed is that the database files binary format is not
compatible with that of rrdtool, if that's a problem.

Also, I don't know if this is how it is supposed to be or if it's a bug in
rrdsharp, but the last value is always NaN if I don't limit the graph to the
value previous to the last.
