Simple Widget that lets you put arbitrary HTML code on a Zabbix Dashboard
Tested on Zabbix 6.4.0
The html_widget directory needs to go into the modules directory of your zabbix web frontend server:
wget https://github.com/shrank/zabbix-widget-html/archive/refs/tags/v1.0.zip
unzip v1.0.zip
cp -r zabbix-widget-html-1.0/html_widget /usr/share/zabbix/modules/html_widget
Rescan and enable the module in the web interface(Administrator->General->Modules)
