Steps to reproduce:
**

I have two single triggers defined:

Warning trigger with expression last(/abc/status)=2
Average trigger with expression last(/abc/status)=3

When status=2, a Warning problem is generated and through the Connector an event is sent:
"eventid":10889,"host":"abc","name":"Test abc is down (2)","severity":2,"value":1,"tags":[\{"tag":"Zabbix.NOC"}]

When status=3 is subsequently detected, an Average problem is generated, the existing Warning problem is closed, and through the Connector an event is sent:
"eventid":10895,"host":"abc","name":"Test abc is down (3)","severity":3,"value":1,"tags":[\{"tag":"Zabbix.NOC"}]

However, the Connector does not send any resolving event for the Warning problem, so it remains open in the webhook.

When status=0 is subsequently detected, the Average problem is closed in Zabbix and through the Connector an event is sent:
"eventid":10902,"p_eventid":10895,"value":0 and the Average problem is closed in the webhook.

However, the Warning problem remains unresolved in the webhook.

For comparison, I also created a Zabbix Action to generate events when a Problem is generated. It can be seen that the Action generates all the necessary events for proper correlation.

 

1. status=2 (Warning problem is generated in Zabbix)

Connector Events:
2026-06-12 09:24:48 "eventid":10929,"host":"abc","name":"Test abc is down (2)","severity":2,"value":1,"tags":[\{"tag":"Zabbix.NOC"}]

Action Events:
2026-06-12 09:24:48 {"ZBX_event":"Error","Host":"abc","EventID":"10929","Event":"Test abc is down (2)","Severity":"Warning","Time":"09:24:46","Tags":"Zabbix.NOC","EventRecoveryID":"

{EVENT.RECOVERY.ID}"}


2. status=3 (Average problem is generated in Zabbix, Warning is closed)

Connector Events:
2026-06-12 09:26:35 "eventid":10933,"host":"abc","name":"Test abc is down (3)","severity":3,"value":1,"tags":[\{"tag":"Zabbix.NOC"}]

Action Events: 
2026-06-12 09:26:35 {"ZBX_event":"Error","Host":"abc","EventID":"10933","Event":"Test abc is down (3)","Severity":"Average","Time":"09:26:33","Tags":"Zabbix.NOC","EventRecoveryID":"{EVENT.RECOVERY.ID}

"}
2026-06-12 09:26:35 {"ZBX_event":"OK","Host":"abc","EventID":"10929","Event":"Test abc is down (2)","Severity":"Warning","Time":"09:24:46","Tags":"Zabbix.NOC","EventRecoveryID":"10932"}

3. status=2 (Warning problem is generated in Zabbix, Average is closed)

Connector Events:
2026-06-12 09:28:18 "eventid":10936,"host":"abc","name":"Test abc is down (2)","severity":2,"value":1,"tags":[\{"tag":"Zabbix.NOC"}]

Action Events:
2026-06-12 09:28:17 {"ZBX_event":"OK","Host":"abc","EventID":"10933","Event":"Test abc is down (3)","Severity":"Average","Time":"09:26:33","Tags":"Zabbix.NOC","EventRecoveryID":"10937"}
2026-06-12 09:28:17 {"ZBX_event":"Error","Host":"abc","EventID":"10936","Event":"Test abc is down (2)","Severity":"Warning","Time":"09:28:16","Tags":"Zabbix.NOC","EventRecoveryID":"

{EVENT.RECOVERY.ID}

"}

4. status=0 (Average problem is closed in Zabbix)

Connector Events:
2026-06-12 09:30:43 "eventid":10940,"p_eventid":10936,"value":0

Action Events:
2026-06-12 09:30:42 {"ZBX_event":"OK","Host":"abc","EventID":"10936","Event":"Test abc is down (2)","Severity":"Warning","Time":"09:28:16","Tags":"Zabbix.NOC","EventRecoveryID":"10940"}
