Since your mail reader does not understand this format, some or all of this message may not be legible. --B_3287759938_29450830 Content-Type: text/plain; charset="ISO-8859-1" Content-Transfer-Encoding: quoted-printable I thought it was working with the last changes suggested by Alex, but still not quite there. The first problem is that if "last / 10 * 10" returns *720, the graph/fetch tool returns me through *730 instead of *720. See the first rrdfetch below - I still get a nan. No problem - I'll just subtract a couple of seconds. Now I get exactly the data I'm after. However, GPRINT still randomly prints 0 instead of 1. In the data below, examples 2 and 5 print the correct value of 1 for queue 2. The queue2_enabled is inverted from a 0 to a 1 and GPRINT prints it correctly. In examples 3 and 4, the data is identical, but GPRINT prints a 0 instead of a 1. The graph looks perfect. It is just the GPRINT that is randomly wrong. An= y other ideas?
