[ELIOT]

hi everyone
i have problem with upload image with 4MB size to zabbix for my background image
first i got this error
<<File is too big, max upload size is 2097152 bytes.>>
so i search internet and got to this post

https://www.zabbix.com/forum/showthread.php?t=43473

i edit this lines in my /etc/httpd/conf.d/zabbix.conf

php_value memory_limit 256M
php_value post_max_size 64M
php_value upload_max_filesize 64M

but its not work and error change to
Image size must be less than 1MB.

after search in fourm and zabbix documentation i got to need edit php.ini file
i increase size of post
upload_max_filesize = 16M


but noting happend
so i got this link that said to increase mysql max_allowed_packet

https://www.zabbix.com/documentation/3.4/manual/web_interface/frontend_sections/administration/general

and i increase that but noting happend
i realy do any thing and increase any size i see in files

i use zabbix 3.4 on centos7

i waiting for your helps and guidance

thanks

Error may be coming from Zabbix frontend.....

look at /usr/share/zabbix/include/defines.inc.php

define('ZBX_MAX_IMAGE_SIZE', 1048576); // 1024 * 1024

change it at your own risk !

Maybe you can just compress image to 1MB ? i think it will affect Zabbix frontend performance.

thank you for replaying
but 1 Mb size for background image is not good in my opinion,because background image use for map that i want to see it on tv screen and it need to have good resolution .


i change this value and its work right . i can upload my image
thanks alot

but why its effect on zabbix performance ??
