Hi All,
i am new to this. I have installed Zabbix 2.4 successfully. i want to configure schedule report via mail. i have downloaded zabbix-pdf-report-0.8, but i don't know how to configure the report. kindly help me how to configure step by step.

Well, it is not really optimized for running unattended (via mail), but it should be doable. You need to configure at least $z_server, $z_user and $z_pass with values that match your setup. I have my reports outside the main zabbix directory at the root level of the WWW. If you have yours somewhere else, you need to adjust $pdf_report_url.

You probably also want to set $user_login = 0, so you won't be prompted for login details, if you are going the mail route.

Then you should be able to do something like this:

# wget -O report.pdf "http://zabbix.domain.org/report/createpdf.php?ReportType=host&HostID=10401&graphs= Graphs&triggers=Triggers&ReportRange=last&timePeri od=Day"
--2015-03-23 16:02:09-- http://zabbix.domain.org/report/crea...timePeriod=Day

Naturally you need to replace zabbix.domain.org with the path that fits your environment and HostID with the ID matching the machine you want a report for (or the hostgroup ID, etc.)

Then you need to mail the PDF after that, usually something like this:

mail -s "PDF report for ZZZZ" -a report.pdf [email protected] <<EOF
Please find attached your PDF report for ZZZZ
EOF

Well, if the web part works fine, then please post what you do on the command-line to generate the PDF, including output.

Are you using wget? Have you followed my example with the few changes you will need to make to fit your environment?

Usually, you should be able to copy what you have done in a given session and copy/paste it in your next reply.

I can see that an extra space has made it into the wget command below. It should have been:
timePeriod=Day.

Other than that, it should be pretty straight forward. Also, you might want a different timeperiod, but again, you should be able to see the options on the webpage.

Are you using Putty or regular SSH? Are you calling from Linux or Windows (or Mac)? Either Putty or e.g. gnome-terminal or Konsole should work well to copy your recent commands to the clipboard for you to insert here.

You may obfuscate the actual URL, if you wish.

Hi selvakumaran.

It looks like you have two spaces that shouldn't be there:
graphs =Graphs
timePeri od=DAY

It ought to work, if you remove those.

I have found an issue with my selectors, to the coming version 0.9 changes graphs to GraphsOn and triggers to TriggersOn to avoid conflict with internal variables.

It works find through the web interface for one host, correct?

At present, you will likely only get graphs for the first host in a host-group. This is fixed in v0.9, which I'm still working on.

the bold letter which i attached txt/html. But in your test output shows Application/PDF

please let me know where can i mistake

**martinm_76** · 25-03-2015, 09:18

Well, then show us the contents of report.pdf. It is either the login page, if you forgot to set $userlogin to 0, or an error message we might be able to use.

I have just tried with $userlogin=1, and I get a file of exactly that length with the contents of the login page. If you want the login page you need to include credentials for wget, which is easier said than done in this case.

You can make a second report directory if you only want to have the reports run without authentication, but for now, set $user_login to 0, please.

It is near the top of config.inc.php

Zabbix Dynamic PDF Report Generation

i have changed. but pdf file not generated. is there any pdf tool will installed or no need .

**martinm_76** · 26-03-2015, 11:03

If you can generate a PDF from the web interface, then things are good and you need to check config.inc.php.

If you cannot generate a PDF from the web interface (for a host), then hopefully there will be some output to guide to towards the reason.

Please try the web interface, select the host and period, check the 'Debug' option and generate a report. Copy the output of the debug page before you click the PDF link at the bottom and paste it here, if the PDF is not actually a PDF.

Do you get file not found, an empty document or something else?
When you are in the directory where you installed the report (should be called report), please run:

ls -la
<copy output and send it>

ls -la reports
<copy output and send it>

Well well! Even though I uploaded the archive as tgz specifically to avoid the issue with tmp and reports needing permissions changed, for some reason yours are incorrect.

The easy solution, and the one that should have already been there, is:

Code:

cd /var/www/html/report
chmod 777 tmp
chmod 777 reports

That should fix it.

Look back to my original reply with wget and mail examples.

Then check:
man 1 wget
man 1 mail
man 5 crontab

You exit 'man' by pressing 'q'

You should have the information you require then.

I also highly recommend going through the book 'Linux in a nut shell' to get a good foothold on the basics of Linux in general.
