One would be to plot an area for max, then an area for avg, then an area in white for min - no stack involved. So you end up with a colour band from min to avg, and a different colour band from avg to max. Another one I've used is : use a CDEF to get the difference between max and min, plot min in white (or transparent), then stack the CDEF on top of that, then draw a line for avg. I tend to use a solid colour for the line, and the same colour (but with a lot of transparency) for the min-max spread - that way the min-max spread area doesn't obliterate what's been plotted before. ___ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users

Re: [rrd-users] updating rrd file with ping min, max and avg times in milliseconds
Thank you I got it now :) appreciate the help.

I am typing the following to update the rrd file: rrdtool update latency.rrd 08/10/2015_11:33:0.40:0.88:0.73 0.40 = Minimum 0.88 = Maximum 0.73 = Average It doesn't work like that. If you want to record the min/avg/max values from a ping then you need to define THREE DSs, eg response_min, response_avg, response_max You can then define your RRAs as required. You cannot be selective about this, so you will end up with all 9 permutations of min of min, min of avg, min of max, avg of min, ... Only three of these (min of min, avg of avg, max of max) are actually useful. ___ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users ___ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
