I am a new user and have the following graph question:
I need to obtain the average of the maximum's that have been collected
over a period of time.
I have 6 RRD's that have been created with the following command, 1 for
each system...
rrdtool create statistics.rrd --start 1203393659 --step 60 \
DS:smh_da:GAUGE:60:1:U \
RRA:AVERAGE:0.5:1:302400 \
RRA:MIN:0.5:1440:60 \
RRA:MAX:0.5:1440:60
...how is it possible to generate a single number that is the average of
all the maximum's that has occurred over
a period of time. I have been using the following command...
rrdtool graph delivery.png --title "Total Delivery Rate (Test)" \
--width 1000 \
--height 250 \
--step 60 \
--start -1d \
--units-exponent 0 \
--interlace \
--vertical-label="Message Delivery Attempts" \
DEF:smvs41=$base/smvs41/statistics.rrd:smh_da:AVERAGE \
DEF:smvs61=$base/smvs61/statistics.rrd:smh_da:AVERAGE \
DEF:smvs81=$base/smvs81/statistics.rrd:smh_da:AVERAGE \
DEF:smvs51=$base/smvs51/statistics.rrd:smh_da:AVERAGE \
DEF:smvs71=$base/smvs71/statistics.rrd:smh_da:AVERAGE \

DEF:smvs51m=$base/smvs51/statistics.rrd:smh_da:MAX \
DEF:smvs71m=$base/smvs71/statistics.rrd:smh_da:MAX \
DEF:smvs91m=$base/smvs91/statistics.rrd:smh_da:MAX \
CDEF:total=smvs41,smvs61,+,smvs81,+,smvs51,+,smvs71,+,smvs91,+ \
CDEF:totalm=smvs41m,smvs61m,+,smvs81m,+,smvs51m,+,smvs71m,+,smvs91m,+ \
VDEF:smh_max=totalm,MAXIMUM \
VDEF:smh_min=totalm,MINIMUM \
VDEF:smh_ave=totalm,AVERAGE \

GPRINT:smh_ave:" %5.0lf" \

HRULE:13100#0000FF:"Site limit" \
LINE1:total#FF0000:"Total MDA"
...the graph is plotted correctly with 'total' however, the value
'smh_ave' does not represent the average of the maximum.
Any help to point me in the right direction?
