I'm using curl to get some of the images, maybe your php installation is missing it ...

http://de.php.net/curl

yep.
download php_curl.dll and move to \php\ext and modified php.ini
now pdf is downloaded but empty, without graphs

[phalek]

are there any files/images created in the plugins/nmidCreatePDF/tmp directory ?

[L0gRuS]

are there any files/images created in the plugins/nmidCreatePDF/tmp directory ?

no, folder is empty

C:\Inetpub\wwwroot\cacti\plugins\nmidCreatePDF\tmp

permisson any full access.

[phalek]

Ha,

seems like I forgot half of the requirements.

Do you have php_gd2.dll installed and enabled ?

[phalek]

can you access the cacti webpage using localhost ?

e.g
http://127.0.0.1/ or http://127.0.0.1/cacti/

?

[L0gRuS]

?

http://127.0.0.1/cacti/

[phalek]

hm, ok.

Now do the following, open the doPDFReport.php file and add the following lines to line 94:

Code: Select all

print "URL: ".$hit[1]." <br>";
print "Image: $imageFile <br><hr>";

so the code block looks

Code: Select all

if ( preg_match("/(.*src=').*(' border.*)/",$line,$lineMatch ) ) {
   #$line = $lineMatch[1].'tmp/image-'.$match[1].'.jpg'.$lineMatch[2];
   $imageFile = "plugins/nmidCreatePDF/tmp/image-".$match[1].".png";
   print "URL: ".$hit[1]." <br>";
   print "Image: $imageFile <br><hr>";
   list($width, $height, $type, $attr) = getimagesize($imageFile); # 160, 60

then try to create a pdf report. it will give you the following errors (probably a bit different to the one here)

Code: Select all

URL: /cacti/graph_image.php?local_graph_id=222&rra_id=0&view_type=tree&graph_start=1229350319&graph_end=1229436719 
Image: plugins/nmidCreatePDF/tmp/image-222.png 
--------------------------------------------------------------------------------
TCPDF error: Some data has already been output, can't send PDF file

If you add the URL to http://127.0.0.1 it should give you a graph image back.
the Image says, where it stores the image file, and what name it uses.

[L0gRuS]

Code: Select all

			   if ( preg_match("/graph_image.php/",$hit[1] ) ) {
				if ( preg_match("/local_graph_id=(\d+)/",$hit[1],$match ) ) {
				   if ( preg_match("/(.*src=').*(' border.*)/",$line,$lineMatch ) ) {
				      #$line = $lineMatch[1].'tmp/image-'.$match[1].'.jpg'.$lineMatch[2];
					$imageFile = "plugins/nmidCreatePDF/tmp/image-".$match[1].".png";
						print "URL: ".$hit[1]." <br>"; 
						print "Image: $imageFile <br><hr>"; 
					list($width, $height, $type, $attr) = getimagesize($imageFile); # 160, 60
					if ( ( $usedPageUnits + intval ( ( $height / 10) * 2 ) + 10 ) > $pageUnits ) {

then i create pdf report... and no graph on report, only date and my test message on top.

hm.

We're getting close,

You're using windows, so maybe the following line in the doPDFCreate.php file is the problem ( line 73 )

Code: Select all

$dataArray = explode ("\n", $output);

change that to

Code: Select all

 $dataArray = explode ("\n\r", $output);

 $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($ch);       
        curl_close($ch);

        $dataArray = explode ("\n\r", $output); 

and nothing ((( no graph on page

[phalek]

ok,

i'm going to setup a windows cacti version to test that ...

[phalek]

Ok, found the error.

FIrst of all, you will need to have anonymous access to view the graphs...
I couldn't figure out how to get the images otherweise right now ...


Next,

in the setup.php at line 56, remove the following part from that big if section:

Code: Select all

&& PHP_OS!='WINNT'

so the whole function looks like

Code: Select all

function nmidCreatePDF_graph_set_options($opt) {
    #//do not cache graphs being edited or zoomed
    if ( !(isset($_REQUEST['action']) && in_array($_REQUEST['action'],array('zoom','properties','edit'))) && !(isset($opt['output_flag']) && $opt['output_flag']==RRDTOOL_OUTPUT_STDERR) )
        $opt['output_flag']=RRDTOOL_OUTPUT_STDOUT;
    return $opt;
}

}

i change code in file, but i not understand this

FIrst of all, you will need to have anonymous access to view the graphs...

guest account or graph? graphs are generated...
or you say about anonymous on ntfs permission?
