I am trying to setup a simple rrd and then graph the data. My data
set is simple.. every 5 minutes my rrd is updated with a number between
1 - 500. I would like the graph to have values ranging from 1 - 500 on
the vertical axis. And the have a 24 hour period represented by the
horizontal axis. I am still pretty confused as how to do this. Here is
what Im trying....
rrdtool create test.rrd \
--start 1077819500 \
I think this is only for 2 hours, i will adjust to 24 hours when i
think i understand ...
then heres what updates the rrd...
#! /usr/bin/perl -w
$amount = 1;
@array = 1 .. 500;
$index = rand @array;
$element = $array[$index];
$date = `/bin/date +%s`;
print "Date = $date - Element = $element\n";
`rrdtool update test.rrd $date:$element`;
the output i get from this is not what i expected to see..
on the vertical axis i get 1.0 to 1.4 not 1 to the highest value
Could someone please help me understand. I just want a graph that tells
me what the number was that was entered into the rrd every 5 minutes.
