Sprint 59 (Dec 2019), Sprint 60 (Jan 2020)
Case:
Time difference between ZabbixServer and ZabbixAgent
This case, triggers doesn't firing nodata function.
Steps to reproduce:
Envriment:
ZabbixServer 4.0.16 and 4.0.11
ZabbixAgent 4.0.16 and 4.0.11 (Time is set 10 minutes ago than ZabbixServer)
ItemSample:
Itemkey log[/tmp/sample.log]
Interval 1sec
TriggerSample:
log[/tmp/sample.log].nodata(60)}=0

For instance:
Occurs when NTP is out of sync.
Result:

Expected:
nodata trigger work
