You cannot do this. RRDtool has no concept of points in time. It knows only about intervals. It would make no sense at all to set an arbitrary interval. Together with heartbeat the interval is well defined. If you don't want the previous interval to be defined, set it to the value that indicates this (NaN aka Unknown). > BTW: This would also fix the problem of graphing things like "modems in This shows why the monitoring setup isn't right. You shouldn't be monitoring modems in use, you should be monitoring the usage of each modem. Don't poll. Read my last reply regarding this subject. I'm monitoring the exact up and down time of a modem. The result is a fraction of modem usage: 0 means the modem wasn't in use at all, 1 means the modem was in use throughout the entire interval, 0.5 means the modem was in use during half of the interval and so on. Use the tool for what it is designed and it makes your live easy, use the tool the wrong way and it makes your live difficult.
