Actually, I see nothing of the sort ! Assuming the data starts at the beginning of the first hump on the graph, I'd say the average is significantly less than 80k. There are several low values (including something that is either zero or close to it) in the graph. >but Speed IN shows ~32000kb/s Could be. Try using rrd fetch to dump the contents of the relevant CF and see what the average of the values actually work out to. >graphics are drawing from the script with such command > > rrdtool graphv graphic-daily_1.png \ > -w500 > -h100 > -b 1024 > --title Daily > --start -12h > --end $now > --imgformat PNG > --interlace > DEF:in=$rdb:IN:AVERAGE > DEF:out=$rdb:OUT:AVERAGE > DEF:in_ex=$rdb:IN_EX:AVERAGE > DEF:out_ex=$rdb:OUT_EX:AVERAGE > AREA:in#00DD00:in > LINE1:out#F15500:out > AREA:in_ex#FF0000:in_ex > LINE1:out_ex#0561FA:out_ex > GPRINT:in:LAST:Speed IN\\: \%6.2lf kbyte > GPRINT:out:LAST: OUT\\: \%6.2lf kbyte > >I tried to insert "GPRINT:in:AVERAGE:Speed IN\\: \%6.2lf kbyte" >but "Speed IN" shows the same wrong speed, and I can not imagine where it >takes that number When you use the LAST function in GPRINT, I'm not sure how it is treated when the only consolidation you have is AVERAGE. I suspect it may be consolidating the "in" CDEF to a single figure using AVERAGE (which is the CF used in calculation "in") and then applying LAST. It cannot show you the LAST value of the data because you aren't storing that. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
