Zabbix browser monitoring?

Question

Browsers

Tell me how to monitor with Zabix whether the browser is currently open on the client?
The fact is that on 20 machines the browser displays information from the server and often the browser itself crashes like "Opanki" in chrome and you need Zabix to notify about such failures
The script does not hang up the server on the web page itself remote access is not available to it

Answer 1

bullshit, put the page auto-update extension, I used to hang for one thing where the browser crashed
