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
rrdtool create statistics.rrd --start 1203393659 --step 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 \
--vertical-label="Message Delivery Attempts" \
COMMENT:" " \
COMMENT:"Minimum Maximum Average\n" \
GPRINT:smh_min:" %5.0lf" \
GPRINT:smh_max:" %5.0lf" \
GPRINT:smh_ave:" %5.0lf" \
COMMENT:" \n" \
HRULE:13100#0000FF:"Site limit" \
...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?
