Everything after this is because the imagecreate() failed.

Except this:

which looks like you don't have PNG support in your php gd module. You can test that by pasting the following into a text file (say test.php) and then running it with php ('php test.php'):

Code: Select all

<?
    $gdinf = gd_info();
    if(! $gdinf['PNG Support'])
    {
        die("Your GD php module doesn't support PNG format.");
    }
    else
    {
        die("You have PNG support");
    }   
    
?>

Version 0.7 now has this test built-in. I'll also make sure it just stops if the imagecreate() fails, too. I still don't see why you get the 'dimensions' error, but having PNG support would certainly help.

you are right :

[root@cacti www]# php test_gd.php
Your GD php module doesn't support PNG format.

but it can draw an png in another version ...

but .. i tried around to fix the error and i took from 1.1.1hj3 version this script :

print "Opening log files...\n\n" if($DEBUG);
foreach $link (keys %target){

$data = $target{$link};
print "FILE: $data\n" if($DEBUG);

if($data =~ /\.rrd$/i)
{
print "LINK: Reading from RRD: $data\n" if($DEBUG);
( $input{$link}, $output{$link} ) = read_rrd_data($data);

print "LINK: $link, Input: $input{$link}\n" if($DEBUG);
print "LINK: $link, Output: $output{$link}\n" if($DEBUG);
}
else
{
if(($data =~ /^https?:\/\//i) || ($data =~ /^ftp:\/\//i) ) {
open(LOG, "$WGET $data |") or warn "$data: $!\n";
} else {
open(LOG, "$data") or warn "data file $data: $!\n";
}

while(<LOG>){
# 
# 
if(/<\!-- cuin d (\d+) -->/){
if($REVERSEDIRECTION)
{
$output{$link}=$1;
}
else
{
$input{$link}=$1;
}
print "LINK: $link, Input: $input{$link}\n" if($DEBUG);
}
if(/<\!-- cuout d (\d+) -->/){
if($REVERSEDIRECTION)
{
$input{$link}=$1;
}
else
{
$output{$link}=$1;
}
print "LINK: $link, Output: $output{$link}\n" if($DEBUG);
}
}
close(LOG);
}
}

and from weathermap4rrd this one:

print "Reading rrd files...\n\n" if($DEBUG);
foreach $link (keys %target){
$data = $target{$link};
print "FILE: $data\n" if($DEBUG);
if ( ! $DATE ) {
$DATE= RRDs::last "$data";
$version=&rrdtool_getversion();
print "RRDTool binary version detected : $version\n" if ($DEBUG);
if ($version=="1.2") {
$DATE= $DATE-300;
}
print "No date specified, last value will be read : ".scalar localtime($DATE)."\n" if ($DEBUG);
}
my ($start,$step,$names,$data) = RRDs::fetch "$data","AVERAGE","--start","$DATE","--end","$DATE";
my $ERR=RRDs::error;
die "W4RRD ERROR while reading $target{$link}: $ERR\n" if $ERR;
print "Start: ", scalar localtime($start), " ($start)\n" if($DEBUG);
print "Step size: $step seconds\n" if($DEBUG);
print "DS names: ", join (", ", @$names)."\n" if($DEBUG);
print "Data points: ", $#$data + 1, "\n" if($DEBUG);
foreach my $line (@$data) {
if(@$line[0] != null) {
$input{$link}=@$line[$inpos{$link}];
$output{$link}=@$line[$outpos{$link}];
print "LINK: $link, Input: $input{$link}\n" if($DEBUG);
print "LINK: $link, Output: $output{$link}\n" if($DEBUG);
}
}
}

and changed the

$input{$link}=@$line[$inpos{$link}-1]*$coef{$link};
$output{$link}=@$line[$outpos{$link}-1]*$coef{$link};

to

$input{$link}=@$line[$inpos{$link}];
$output{$link}=@$line[$outpos{$link}];

so, now the version, that didn't get the data and drawing ok - working ok, but it recieve in inpos and outpos the same data

You might need to tell the php configure command where to find it. You may need to add somehing like

Code: Select all

--with-png-dir=/usr/local

to the end of your config line (for wherever you installed libpng). The configure output includes a little section of which image formats will be supported if you look through it.

kslt · Post by **kslt** » Thu Sep 29, 2005 7:54 am

did it already..
the php was compiled with:

./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/bin/mysql --with-png-dir=/usr/local --with-gd=/usr/local/lib --with-zlib-dir=/usr/local/lib

Then it seems you might need to ask a PHP forum

Actually - one other thing! Make sure you don't somehow have two PHPs installed. If you do 'php -v' and 'which php' on the command-line, do they give the values you expect? I got burned this way once - updating and updating but somehow still running the old PHP 4.0.3 I had in /usr/bin and not the one in /usr/local/bin

yes, tested ..
i havn't another version from the begining ...

ok .. doesn't metter ..

can you help me with the getting data from rrd's ?
cause i found already that it get wrong data and in and out data equal and wrong ...

maybe another version ? can you recommend me to try any one ?

If I understood which version you were talking about, it was my old perl version, but with some code taken from somewhere else added on. The part that actually reads RRDs is not very complex. If you understand it enough to modify it, then you probably understand it enough to debug it. From memory, you will run into problems if you have a custom RRD, where there are more than two DS in it, or where the order is different.

I still recommend that you get one of the PHP versions (mine, or wm4rrd) working as there will be no bug fixes or updates for my perl version. I'm spending my spare time working on the next release for php-weathermap.

Hi,
I freshly install Cacti 0.86g
Weathermap4rrd-perl-1.2rc3
when I want to run weathermap I got this error message

[root@PIONEER weathermap]# ./weathermap

Line 12 is:

and I change the RRDTOOL_PATH as:

$RRDTOOL_PATH = "/usr/local/rrdtool/bin/";

Can anybody tell me the solution?

I've never used wm4rrd

but the error is to do with the perl module not the rrdtool executable. Somewhere near the top of the script there should be something like:

Code: Select all

use lib qw(/usr/local/rrdtool-1.2.3/lib/perl);

or wherever you installed the RRD perl modules to. ('locate RRDs.pm' should tell you).

TFC · Post by **TFC** » Wed Oct 12, 2005 8:20 am

I installed perl
I installed rrdtool like

./configure --prefix=/usr/local/rrdtool

then i searched RRD.pm, i found in source directory.
I copied it to /usr/local/rrdtool/lib directory.
Then I tried to run werahermap4rrd
But i still get same message.
