[rrd-users] Re: how to use RRDs::graph in a perlscript?

[Christian_Lair at i2.com]

Here's an example from one of my scripts that works just fine. If you 
include your code we may be able to help you in detail.
my $start_90 = ($today - 77760000);

RRDs::graph     "$graph_location/$host/90day.gif",
                "--start", "$start_90",
                "--title", "90 Day Graph",
                "--w","375", "--h", "200",
                "--x", "WEEK:1:MONTH:1:MONTH:1:0:%b",
                "DEF:LoadAvg=$rrd_location/$host/$host.rrd:load:AVERAGE",
                "LINE2:LoadAvg#FF0000:Load Average",
                "DEF:CPU_Load=$rrd_location/$host/$host.rrd:cpu:AVERAGE",
                "LINE2:CPU_Load#00FF00:CPU Load",
                "DEF:Vmem_Load=$rrd_location/$host/$host.rrd:vm:AVERAGE",
                "LINE2:Vmem_Load#0000FF:VM Load",;

my $ERR=RRDs::error;
die "ERROR while creating 90 day graph: $ERR\n" if $ERR;

How to use it? A proper documentation wwith examples would be helpful.
Thanks.
