Creating a trigger in Zabbix 5.4?

Question

Zabbix

I'm trying to create a trigger, I did it before, everything worked, I don't understand what I'm doing wrong

Answer 1

https://www.zabbix.com/documentation/current/manua...
A new find function replaces str, regexp, iregexp
Function description:
https://www.zabbix.com/documentation/current/manua...
Now should be like this:
find(/host/key,"like","error")

Answer 2

Old syntax:
{host:key.func(params)}=0
New syntax:
func(/host/key,params)
