hi team,
in Home -> performance graphs, the report show in screen ok but when we send it on email, full blank graphs.
Report file size is 35KB. No error log found in /var/log/httpd/error_log file.

Try the two different options available under the Performance Settings page (Admin > System Config > Performance Settings > PDF/JPG Exporting):

1. Use patched jQuery 1.x to render PDF/JPG reports = selected
2. Use patched jQuery 1.x to render PDF/JPG reports = not selected (check-box is cleared)

When you use the second option, increase the Default Delay value, and click on Updated Settings. You may try different values, depending on the size of your report.

Let us know if this helped.

hi lmiltchev,
i think option 2 work fine, but have another problem. When i set Schedule page for send the mail. it's not stable, some time show all graphs, sometime show blank. The error report have file size smaller than the normal report. pls see the pictures.
If i use One time report and send immediately, it will fine, no error.

Error_log show like this when i set/edit a report schedule:

I have tried change the permission of files but not effect :

[root@nagiosxi01 scheduledreporting]# ls -l | grep schedule
-rwxrwxrwx. 1 nagios nagios 26100 Mar 4 17:53 scheduledreporting.inc.php

[root@nagiosxi01 var]# ls -l scheduledreporting.log
-rwxrwxrwx. 1 nagios nagios 8649 Mar 18 10:23 scheduledreporting.log

This is very strange. Have you tried increasing the Default Delay value even more to see if this is going to help?

We will try to recreate the issue in house and get back to you. Meanwhile, can you run the following commands and show the output?

i have already changed Default Delay from 300 to 500 and 700 but not effect.

[hangltt@nagiosxi01 ~]$ ls -lad /usr/local/nagiosxi /usr/local/nagiosxi/var
drwxr-xr-x. 10 root nagios 4096 Feb 19 21:08 /usr/local/nagiosxi
drwxrwxr-x. 7 nagios nagios 4096 Mar 19 09:05 /usr/local/nagiosxi/var

[hangltt@nagiosxi01 ~]$ grep nag /etc/group
nagcmd1000:nagios,apache
nagios1001:nagios,snmptt,apache

[hangltt@nagiosxi01 ~]$ chage -l apache

The permissions look fine. I don't see any issues with them.

Try increasing the value higher, e.g. 5000 or even more.

Also, increase your resource limits in the php.ini file (if you haven't done this already):

https://support.nagios.com/kb/article/n ... e-611.html

If this is not helping, please open a support ticket via our support center here:

https://support.nagios.com/tickets/

and include your latest profile (Admin > System Config > System Profile > Download Profile).

Try increasing the value higher, e.g. 5000 or even more. --> not effect as well bro. I sent a ticket already.

Pls help me a second question :
Can we set Performance graphs work on Host Group? We have more than 300 servers and we can not read 300 email for all hosts.
I need it work on host group, and it have all services inside this.
