Thanks Craig,
After an array learning curve, I've come up with the following line that works.
$opts_DEF[] = str_replace(output,output_max,$opts_DEF[output]) . ":reduce=MAX";
Since the data I'm looking for has already been called in with the
rrdtool_get_def function call, this gives me the line I want without
the extra overhead. I've added the extra CDEF lines and GPRINT to get
something that I'm pretty sure will work. For testing I put some
hooks in to send the output to a file, and I get the expected rrdtool
call.... Problem is... It needs the features of rrdtool-1.2. I can
send a copy of the file if wanted...
On another note, one of my pet-peeves on the traffic graphs has been
the way bandwidth is represented. I find myself counting zero's way
too much. I've shamelessly adapted some code I've found in the PHP
Manual. It's suppose to work with PHP 4.3.0 or higher.
I've added the following lines....
$speed_notation = array(" bps", " Kbps", " Mbps", " Gpbs", " Tbps");
$in_bandwidth = round($data["bandwidthin"]/pow(1000, ($i =
floor(log($data["bandwidthin"], 1000)))), 2) . $speed_notation[$i];
$out_bandwidth = round($data["bandwidthout"]/pow(1000, ($i =
floor(log($data["bandwidthout"], 1000)))), 2) . $speed_notation[$i];
and changed the Comment lines to be....
"COMMENT:'Inbound Bandwidth: $in_bandwidth'",
and "COMMENT:'Outbound Bandwidth: $out_bandwidth\\n'",
This changes the bandwidth displayed into a more readable format.
Thanks....
