[rrd-users] Re: lost data on graph

[Li, Charles]

I am trying to plot forms response time.

I created a rrd with the following:
+++++++++++++++
rrdtool create forms_processtime.rrd \
--start N \
--step 300 \
DS:forms_processtime:GAUGE:600:0:10 \
RRA:AVERAGE:0.5:1:86400
+++++++++++++++

After creating a graph with:
+++++++++++++++
rrdtool graph graph_name \
DEF:forms_processtime=forms_processtime.rrd:forms_processtime:AVERAGE
LINE1:forms_processtime#FF0000 \
GPRINT:forms_processtime:MAX:"%lf" \
-s $start_time_in_sec_6am -e $cur_time_in_sec \
--no-minor -a PNG -w 400 -h 300 \
-t "*Forms Run Time Performance Data for "$cur_server
+++++++++++++++

I saw the MAX value display is 0.096.
I know that I have other values that are higher than 0.096, ie 0.226, 0.119,
etc..., which I confirm with the fetch function:
+++++++++++++++
rrdtool fetch forms_processtime.rrd AVERAGE -r 1 -s 1068922800 -e 1069392186
| grep -v nan | grep -F "e-01"
1068955200: 2.2631333333e-01
1068963000: 1.1908000000e-01
1068991200: 1.3447333333e-01
1069020300: 1.1738000000e-01
1069033200: 1.2168666667e-01
1069058100: 1.1092000000e-01
1069071600: 1.4121333333e-01
1069107300: 2.0028000000e-01
1069111800: 2.4645333333e-01
1069331100: 1.1736000000e-01
1069348200: 1.4749333333e-01
+++++++++++++++

So, why is the graph not showing 0.236 and 0.119?

Please help,
Charles
