Hi,
I have a strange behavior on my graphs. Here is the data source I use to generate the graph : http://img11.imageshack.us/i/image001ki.png/ As you see I inserted manually a 10 value to generate a high point in the graph. The timestamp 1299062660 is 11:44:20 (GMT +1) Now is the output rrd graph : http://img534.imageshack.us/i/image002pjf.jpg/ And my rrd definition : rrdtool info 1.rrd : filename = "1.rrd" rrd_version = "0003" step = 60 last_update = 1299063080 ds[time].type = "GAUGE" ds[time].minimal_heartbeat = 600 ds[time].min = NaN ds[time].max = NaN ds[time].last_ds = "1.800000e-02" ds[time].value = 3.6000000000e-01 ds[time].unknown_sec = 0 rra[0].cf = "AVERAGE" rra[0].rows = 525600 rra[0].cur_row = 304990 rra[0].pdp_per_row = 1 rra[0].xff = 5.0000000000e-01 rra[0].cdp_prep[0].value = NaN rra[0].cdp_prep[0].unknown_datapoints = 0 As you can see, only 1 point is needed to make a CDP. Something I don’’t understand is why the high point in my graph starts at 11h43, then go down a little at 11h44, and drops at 11h45, when the high data point is at 11h44. Because the value at 11h43 is 0.021 as you can see in my mysql data points … Why is there such a lag of 1 interval ? I hope you understood me :=) Thanks for any help _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
