[rrd-users] Create Graph with 2 "AREA"

[Martin Friberg]

Hey Simon

yes itried that but for some reason it still goes up on the axis



code to generate the db

$RRDTOOL create $FILE -s 60 \
DS:ping:GAUGE:120:0:65535 \
RRA:AVERAGE:0.5:1:2880


code to update db

UPDATECMD=$(ping -c 3 -w 6 $HOST | grep rtt | awk -F "/" '{ print $5 }' )
$RRDTOOL update $FILE N:$UPDATECMD

UPDATECMD2=$(ping -c 3 -w 6 $HOST2 | grep rtt | awk -F "/" '{ print $5 * 
-1 }' )

$RRDTOOL update $FILE N:$UPDATECMiD2

code to generate graph

$RRDTOOL graph $OUTPUT \
         -t "WAN Ping" -v "Time in ms" \
         --start="now-1d" \
         --end="now" \
