CereusReporting problem

[Rickylolz]

Hello everybody,

I just finished installing the CereusReporting plugin on my Cacti server.
However, I encounter a problem:

When I try to generate a PDF report I have the following error message :

FPDF error: Undefined font: B on http://cacti/plugins/nmidCreatePDF/createPDFReport.php page

I did several researchs on Google but didn't found anything...

PS : I'm using CereusReporting v1.83.42

Any idea ?

Thanks a lot

hi Rickylolz,

Can you download and extract the following file into the "ReportEngines" directory and try again ?

http://redmine.nmid-plugins.de/attachme ... ode_45.tgz

[Rickylolz]

Hi Phalek,

Done... but it still doesn't work..
But I'm surprised that the folder named "mpdf" wasn't present in the "ReportEngines" directory before i extract your archive into, there was only a "fpdf" folder (and severals php file)

Anyway, thanks for your reply

[phalek]

Ok, need to dig into this.
Nevertheless, you should now be able to switch to that ReportEngine from the NMID settings tab. It should solve that issue.

[Rickylolz]

Indeed, i switched to mpdf but now I have a kind of "load-loop" when I try to generate a report (the page load but nothing happens, loadbar still empty or half complete)
During this load nobody can access the cacti server.. I Had to reboot it

[phalek]

wow, I've never seen that happen ...

Switch back to the FPDF engine then and check your debug info page. Maybe a module is missing.

Does any error log show what happened here ?

[Rickylolz]

I switched back to FPDF and now I don't have the error linked to the undefined font any more..

Here is a sample of the debug page :

Installed CereusReporting Extenstions:
File parallelGraphRetriever.exe does not exists ( D:\Program_Files\Wamp\www\cacti\plugins\nmidCreatePDF\parallelGraphRetriever.exe )

Thanks for your assistance

[phalek]

Ok,

You will need to download and install the "parallelGraphRetriever.exe" extension for the reports to generate correctly.

Other than that, a quick question: Did you go to the settings tab and hit the save button at least once after the install and before that FPDF error occured ?

[Rickylolz]

I put parallelgraphretriever.exe in the nmidCreatePDF directory but i have still the same problem (with both FPDF and MPDF)

Yes, I hit the save button

[phalek]

Do you see any error messages ? Especially any php related ones ?

[Rickylolz]

Nothing...

After furthers investigations, it only works when I go to the detailed view of a graph (the pdf generation works fine)
In the general view ("Showing all graphs"), there is a "load loop" when I try to generate a report

[phalek]

Maybe this a php memory/execution time error. Can you increase the following settings in your php.ini file:

Code: Select all

max_execution_time = 60     ; Maximum execution time of each script, in seconds
memory_limit = 128M      ; Maximum amount of memory a script may consume

[Rickylolz]

Done.. Just restarted apache and I've still the same problem..
Stucking to "createPDFReport.php" while trying to generate a report..

Thanks for your assistance anyway

[phalek]

Odd ...

Nevertheless, can you quickly sum up what kind of system you have and how you installed Cacti on it ? I want to play around with re-creating the issue. I don't think I have a (paying) customer actually running it on Windows system, though I know some use the express version on Windows.

I bet it's probably just a minor issue ... that minor that it's easily overlooked ...

[Rickylolz]

I am using Cacti Version 0.8.8a on a Windows Server 2003 R2.
My web service is "WAMP based"

Also, I'm using the Express edition of CereusReporting plug-in..
