Zabbix Dynamic PDF Report Generation

[5song]

martinm_76 Is the PDF generation supposed to work under docker container zabbix-web-nginx-mysql with nginx not Apache? If yes, could you please advise setup procedure? Is there any difference with setup for no container environment? My setup is Ubuntu 20.04, Zabbix 5.0.2. Thanks.

I can't really say, I have not tried. My only experience thus far is with Apache. It should work with other webservers, but might require extra configuration. If other PHP stuff works fine, I would expect it to be a matter of having the proper modules available in php and possibly some tweaks to the default php config.

Hello,

My setup is centos7.2.1511,nginx/1.16.1,PHP 5.6.32

Pdf file generated, available for download, but no graphs in it.

This is the error message:
[error] 4990#0: *7299 FastCGI sent in stderr: "PHP message: PHP Warning: Creating default object from empty value in /usr/share/zabbix-pdf-report/inc/ZabbixAPI.class.php on line 123" while reading response header from upstream, client: x.x.x.x, server: mnt.1cloudtech.com, request: "POST / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxx.com:8200", referrer: "http://xxx.com:8200/"

Thanks

I don't know if there are issues with using nginx instead of Apache, but if so, I would expect them to be minor. I see some people mention having the host listed in /etc/hosts could be helpful. Normally it should be anyway, but sometimes you might call it with a different name that the actual host or similar... If that doesn't fix it, maybe create a bug on github so we can try to trace it.

I have the same Unable to login: issue. I did the same steps mentioned in the document but getting the errors.

Can you please give some suggestions to fix it?

Hi,

For those with the "Unable to login" issue, in my case it was only the server can not resolve the DNS name of the Apache's Virtualhost Servername. I included the name in /etc/hosts file and the problem was gone.

Best regads,

Hi everybody,

Thank you very much for this plugin. It is very useful as a reporting tool. Great work and thanks for sharing. I got it working (v1.2.4) with Zabbix 4.0.4 LTS on a Debian 10.

One question: is there a way to change the Zabbix image logo in the report? I can obviously enable/disable it, but I tried to change the image with no success. Even replacing the original image for another one with exact same size (pixels), the image on the report simply dissapears. Any restrictions with the size of the image (Kb)?

Thank you very much and best regards.

Hello Everyone,

I have installed zabbix 5.4 with zabbix webservice on centos 8 and no doubt it is working fine.

I want to generate report in PDF format so that I have configure the zabbix dynamic pdf generator. It creates the report but I found that there is no data in generated graph.

I am trying to find out that what's the problem behind it? How can I resolve that issue?

Any help will be appreciated.

[martinm_76]

When you ask for the exact same data in Zabbix, is there a graph? As far as I can tell, for most things, Zabbix only keeps 7 days of history by default and once those are gone, all that is left is trends. Was this within the last 7 days? Basically, Zabbix is creating the graph and if data is shown in Zabbix it should also be in the report, if all required modules and stuff are available. If you enable debug is there any further information?

Hi, I have Zaxxix 6.0 Alpha and it doesn't seem to work - whatever credentials I use, report generator always says 'unable to login'. Probably a Zabbix version issue?

[gofree]

alpha is alpha, could be highly unstable

The API validation was added to Zabbix 6.0 and above in /usr/share/zabbix/include/classes/api/services/CHostGroup.php
so kindly remove the following parameter in /usr/share/zabbix/zabbix-pdf-report-master/chooser.php

please remove the two parameter 'real_hosts'=>'1','with_graphs'=>'1'

$host_groups = ZabbixAPI::fetch_array('hostgroup','get', array('output'=>array('groupid','name'),'real_host s'=>'1','with_graphs'=>'1','sortfield'=>'name') )
or die('Unable to get hosts: '.print_r(ZabbixAPI::getLastError(),true));

please remove the two parameter 'real_hosts'=>'1','with_graphs'=>'1'

$host_groups = ZabbixAPI::fetch_array('hostgroup','get', array('output'=>array('groupid','name'),'sortfield '=>'name') )
or die('Unable to get hosts: '.print_r(ZabbixAPI::getLastError(),true));

otherwise commend the validation line in /usr/share/zabbix/include/classes/api/services/CHostGroup.php
/*

self::exception(ZBX_API_ERROR_PARAMETERS, $error);
