Empty trigger alarm under trigger status

[aink999]

Hi I don't know what happened but I have this empty trigger under /tr_status.php:

Not classified PROBLEM 08 Jul 2013 15:24:00 1h 24m 21s Acknowledged Add

It has no host and no name. How can I get rid of it ? I already restarted my Zabbix server.

Click on date, and also click on date in the next (event) gui. Then you should have " Event source details" where you can see source of the trigger under Expression.

Found an answer

I follow the instruction in this link

https://support.zabbix.com/browse/ZBX-5439?page=com.atlassian.streams.streams-jira-plugin:activity-stream-issue-tab

delete from triggers where triggerid not in (select triggerid from functions);
delete from events where source=0 and object=0 and objectid not in (select triggerid from triggers);

That remove the "ghost" alarm with no hostname.
