Thruk v3.02 - Report not rendering PDFs & Emails not working

[MattCrum1]

Describe the bug I am running Thruk & Naemon in an AlmaLinux container - trying to use the Report functionality to email an active Service problems report every day based on a URL and am having 2 problems:

1. Report does not render PDFs

I'm using the URL:

/thruk/cgi-bin/status.cgi?host=all&servicestatustypes=28

The report renders fine in HTML, but is about 15MB; not suitable for emails. I switched to PDFs and the generated file is 3 pages of white space with a couple of navigation elements (scrollbars etc); no service information.

I've tried using the absolute URL https://servername:port/thruk/cgi-bin/status.cgi?host=all&servicestatustypes=28 but the behaviour is the same.

2. Report is not emailed Emails from Naemon work fine, but the report emails do not. I have sendmail configured on the server to use our internal mail relay and testing it using 'echo "test" | sendmail -s subject [email protected]' works fine. Using the "Send Report By Email" feature results in a page hang for 1 minute, then returns to the reports page with no errors on screen. See Thruk log below.

Thruk Version 3.02

To Reproduce Steps to reproduce the behavior:

1. Create a report like this with the URL /thruk/cgi-bin/status.cgi?host=all&servicestatustypes=28
2. Create a report preview with PDF disabled and view - it works, but is around 15MB
3. Create a report preview with PDF enabled and view - it creates a blank page with navigation elements displayed
4. Click Send Report By Email and email the report - the UI loads for about 60 seconds, then returns to the Reports page - no email is received

Expected behavior Report PDF is generated correctly Email is sent
