You can increase the number of attempts in web scenario to eliminate some of the false errors.

You can use the min / max function for this purpose.

For example

{Zabbix server:web.test.fail[http:example.com].min(12m)}>0

The trigger will work if the site is unavailable within 12 minutes.

And with this example

{Zabbix server:web.test.fail[http:example.com].max(12m)}<1

You can return the trigger to working condition if the site is available for more than 12 minutes
