Dear Zabbix support,

It seems there is something wrong with Zabbix trapper items and the nodata() function.
I have a Zabbix trapper text item from which I need to configure a trigger which fires for any new value, and which automatically turns to OK in case no value is received for a given timeout (60s for example).

I tried different expression without success (See my post here: https://www.zabbix.com/forum/showthread.php?t=57712)

I finally come to the following simple expression which is still not working :

Problem:

{MyHost:myZabbixTrapperItem.regexp(.*)}=1

Recovery:

{MyHost:myZabbixTrapperItem.nodata(60)}=1

I don't see any good reason for this simple definition to not clear my alarm after 60sec.

Thanks in advance for your help.
