No graphs on reports with nmidCreatePDF

[hmorandell]

Hello,

I have setup the nmidCreatePDF plugin on my site. I have folleowed all suggestions (I think I did it right, but it is not working. Here the output of the debug file:

nmidCreatePDF Debug Page

Dir: /srv/www/htdocs/cacti/plugins/nmidCreatePDF
Main Dir: /srv/www/htdocs/cacti/
PHP_SELF: /cacti/plugins/nmidCreatePDF/debug.php

soap enabled
Installed nmidCreatePDF Extenstions:
File parallelGraphRetriever exists
File getSmokePingPath does not exists

When I look in the apache error logfile, I keep getting always the following error:

sh: .parallelGraphRetriever.exe: command not found

I have a linux server and I have downloaded the windows version of the parallelGraphRetriever file. I have no idea where the "parallelGraphRetriever.exe" come from....

I get the pdf file, but there is no image in it. The files have all the right permissions. In the "tmp" folder I get a workerfile, but no images.
The workerfile always contains something similar like:

graph@php create_image.php 32 5 1272819253 1272905653 120 600 > tmp/1272905655-61-1272819253-1272905653/32.png@DEHN_20000003338 - Traffic@@tmp/1272905655-61-1272819253-1272905653/32.png@32

Anyone an idea what I'm doing wrong? I have a certain cacti and php knowledge, but this time I'm stuck and don't know what else to do...

I found now that when I click on an image and generate the pdf report from there (graph.php), the report works and I get the graphs correctly in the pdf.
But generating the report from graph_view.php I get always a blank report.

Anyone an idea?

I will have a look into this. There seems to be a problem with the OS detection. It may be enough for now to just rename the parallelGraphRetriever file to the parallelGraphRetriever.exe name ...

[hmorandell]

Hi,
I have tried to create a symlink for parallelGraphRetriever.exe to parallelGraphRetriever but it does not work anyway.....

[phalek]

can you zip the nmidCreatePDF directory and send me the file to support @ urban-software.de

Hello,

For information, I have exactly the same problem than hmorandell.
My cacti installation is running under Ubuntu server 10.4 64 bits.

Everything is fine on the nmidCreatePDF debug page but the "sh .parallelGraphRetriever.exe: command not found" is logged under apache error log everytime I try to generate a report from graph_view.php or from nmidCreatePDF_GenerateReport_now.php.

No problem with the graph.php

Hi,
I'm using OpenSuse (unfortunatelly.....)

[phalek]

anyone able to provide me access to the systems ? I can offer using Teamviewer ...

[phalek]

Hi,

Can you (both) execute the following on the CLI and provide me the results ?

Code: Select all

php -r "echo PHP_OS;";

[phalek]

I have created an enhanced debug.php file. Please download it here and replace the exiting one with it. Then point your browser to it and provide the output of the file to me. It will help in finding the problem of this error.

Hi Phalek,

Thanks for your help.
The result of the php command just give me: Linux

And here is the result of the new debug.php (I only mask my hostname computer)

Regards

[phalek]

ok, is there anything special to the system i need to be aware of ? If there's nothing special to it, I can try to reproduce it in a virtual Ubuntu 64bit system ...

[catcha8]

Well I guess no... But I remember something for the SourceGuardian module installation. There's 2 php.ini files for my installation, one for the CLI and one for the web server:

Code: Select all

/etc/php5/apache2/php.ini
/etc/php5/cli/php.ini

Don't know if it can help.

If you prefer, I can give you access to my system.
Just give me information by mail.

Regards

[phalek]

Would you be available in about 4 to 5 hours ?
