Afaik, after a quick research, the PDF export function is provided by Icinga Web 2 and there is some communication issue between the function and the module?!
At least that’s what I got out of reading this bug:
Can anyone share some insight into this?
Do I even missed something to configure and that’s why the graphs are not shown?
Icinga Web 2.6.3
Graphite 1.1.0 (git commit cb2a94397529f5a4b73d423fe89fabf2b0f064a6)
In which log file would if find the information? /var/log/icingaweb2/icingaweb2.log is empty
The apache error log only shows errors for the previously missing php-mbstring package, which I have installed.
Yeah, typically that log location. Inside the Vagrant boxes with CentOS 7 this works like a charm, you’re likely using Debian/Ubuntu then right?
The error sources directly from dompdf, with using Icinga Web 2.6.3 I’d assume you’re just using what’s bundled - and not some external reference. Might be worthwhile to look into library/Icinga/File/Pdf.php and play around with its options, as this issue and this one suggest.
