All my dashboards graphs lost text description. Even in host configuration, when I click preview in graph there is no text. Checked on Chrome and Firefox. Tried to recreate dashboard, cleaned browser cache. I googled that it can be issue with fonts. Checked... Still not solved.
verify permissions for '/usr/share/zabbix/assets', if not 'www-data:www:data'
chown www-data:www-data assets/
If the file does not exist (/usr/share/zabbix/fonts/graphfont.ttf):
cd assets/fonts/
Copy the file graphfont.ttf to /usr/share/zabbix/assets/fonts/: (source: https://support.zabbix.com/browse/ZBX-16182)
cp /usr/share/zabbix/fonts/graphfont.ttf /usr/share/zabbix/assets/fonts/
Or link the file:
ln -s /usr/share/zabbix/fonts/graphfont.ttf /usr/share/zabbix/assets/fonts/
