rrd


Hi,

I have a problem with my rrd. In /usr/local/www/data/cable/rrd/ I have created rrd's

db10-C.rrd db10.rrd db9-C.rrd db9.rrd db8-C.rrd db8.rrd

In /usr/local/www/data/cable/rrdimages/ I have

db10-C-day.png db10-day.png db9-C-day.png db9-day.png db8-C-day.png db8-day.png

I need to get graphs for one hour, trhree hours, six hours, for week, month and year, but I can not do that.

Olso in /usr/local/www/data-dist/cable/inc/ I have two php files graph.php and graphc.php

graph.php

<?
// Function for graphing

function graph($time, $node) {


include ("inc/colors.php");
include ("inc/time.inc");

$rrdgraph = "/usr/local/bin/rrdtool graph /usr/local/www/data/cable/rrdimages/".$node."-".$time.".png \
--step 60 \
--slope-mode \
--interlaced \
--start " . $backtime . " \
--vertical-label 'Power (dBmV)' \
--width '670' \
--height '220' \
--title 'Statistics for " . $node . "' \
'DEF:A=/usr/local/www/data/cable/rrd/" . $node . ".rrd:max:AVERAGE' \
'DEF:B=/usr/local/www/data/cable/rrd/" . $node . ".rrd:min:AVERAGE' \
'CDEF:down=A' \
'CDEF:up=B' \
'COMMENT:\\n' \
'AREA:down".$dcol.":Power' \
'LINE1:down".$dlcol.":' \
'GPRINT:down:LAST:Last=%6.2lf%s' \
'GPRINT:down:MIN:Min=%6.2lf%s' \
'GPRINT:down:AVERAGE:Average=%6.2lf%s' \
'GPRINT:down:MAX:Max=%6.2lf%s' \
'COMMENT:\\n' \
'LINE1:up".$ucol.":' \
'COMMENT:\\n' \
'COMMENT: " . $grdate . "\\r'";

echo $rrdgraph . "<br>";
exec ($rrdgraph) or die("<br><b><font size='2'>No RRD<p>");

// echo "<fieldset><div align='center'><font face='Verdana' size='2'>" . $node . "-" . $time . "</fieldset>";
echo "<IMG SRC='rrdimages/" . $node . "-" . $time . ".png' alt=" . $node . ">";

......

?>


graphc.php


<?
// Function for graphing

function graphc($time, $node) {


include ("inc/colors.php");
include ("inc/time.inc");

$rrdgraph = "/usr/local/bin/rrdtool graph /usr/local/www/data/cable/rrdimages/".$node."-C-".$time.".png \
--step 60 \
--slope-mode \
--interlaced \
--start " . $backtime . " \
--vertical-label 'Power (dB)' \
--width '670' \
--height '220' \
--title 'Statistics for " . $node . "' \
'DEF:A=/usr/local/www/data/cable/rrd/" . $node . "-C.rrd:u1:AVERAGE' \
'DEF:B=/usr/local/www/data/cable/rrd/" . $node . "-C.rrd:u2:AVERAGE' \
'DEF:C=/usr/local/www/data/cable/rrd/" . $node . "-C.rrd:u3:AVERAGE' \
'DEF=/usr/local/www/data/cable/rrd/" . $node . "-C.rrd:u4:AVERAGE' \

That would depend on how you created the graphs to start with, and the update periods you defined. RRDTOOL is fairly complex, have you gone through the manual and docs? What errors do you get when generating the graphs?
