Pessoal,

Alguem que tenha conhecimento do método 95 percentil, saberia me 
informar se está correto essa criação de gráfico com o rrdtool?

rrdtool graph teste.png -s now-30d -e now -w 500 \
         DEF:in=teste.rrd:ds0:MAX \
         DEF:out=teste.rrd:ds1:MAX \
         CDEF:max=in,out,MAX \
         CDEF:sum=in,out,+ \
         VDEF:total=sum,TOTAL \
         VDEF:perc=max,95,PERCENT \
         VDEF:maxvalue=max,MAXIMUM \
         VDEF:minvalue=max,MINIMUM \
         VDEF:avgvalue=max,AVERAGE \
         LINE1:max#00FF00:"Valor máximo de entrada ou de saída\n" \
         AREA:max#00FF00 \
         COMMENT:"Valor Máximo\:" GPRINT:maxvalue:"%1.2lf %Sbps\n" \
         COMMENT:"Valor Mínimo\:" GPRINT:minvalue:"%1.2lf %Sbps\n" \
         COMMENT:"\n" \
         LINE1:avgvalue#FF0000:"Média geral\n" \
         COMMENT:"Valor\:" GPRINT:avgvalue:"%1.2lf %Sbps\n" \
         COMMENT:"\n" \
         LINE2:perc#0000FF:"95 percentil\n" \
         COMMENT:"Valor\:" GPRINT:perc:"%1.2lf %Sbps\n"\
         COMMENT:"\n" \
         COMMENT:"Total tranferido (in+out)\:" GPRINT:total:"%1.2lf %Sbps\n"
