Zabbix Trigger Tag Regex - doesn't work

[Vaku]

Hi,

I am trying to implement an event correlation based on official Zabbix documentation:
https://www.zabbix.com/documentation...lation/trigger
https://www.zabbix.com/documentation...ger/event_tags

I have created a Log Collector Item, which reads log file and received latest data for this item is of the following format:

2019.07.22 09:37:29 some.host.com 255316 Problem: Zabbix server unavailable

2019.07.22 09:37:29 some.host.com 255316 Resolved: Zabbix server unavailable

I have setup a Trigger with the following trigger expression:

 {Template App Zabbix Alerts:log[/var/log/alerts/alerts.log].regexp([2-9]{1}[0-9]{3}\.[0-9]{2}\.[0-9]{2} [0-9]{2}\:[0-9]{2}\:[0-9]{2} [a-zA-Z0-9._-]* [0-9]* Problem\: .*)}=1

This works fine, the problem gets generated once I update log with new record.

But the same regex doesn't work for Trigger Tags and also doesn't work in Trigger Title.
Please check attached image:



Could anyone help me with this problem?
It's not clear why the same regex doesn't work for Trigger Tags. Might be a bug of Zabbix or something.

Update: works fine. Missed double quotes in regex and "^", "*" tokens.
Not sure why there are so many different regex syntaxes in Zabbix.
Logically, this should be the same for Trigger Expression and Trigger Tags
