 Description   

The data in the Problems becomes inconsistent with the actual data in the items when i use a combination of dependent items in a Trigger that can generate multiple problems with tag-value based resolving (see attached template).

 

Steps to reproduce:

  1. Import the attached template
  2. Create a host named 'ZBUG' and apply template Zabbix-Bug
  3. Run the zabbix_sender to send a lot of data to the server at once
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29028, "eventname": "example 29028", "eventstate": "PROBLEM",  "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29028, "eventname": "example 29028", "eventstate": "RESOLVED", "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29029, "eventname": "example 29029", "eventstate": "PROBLEM",  "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29030, "eventname": "example 29030", "eventstate": "PROBLEM",  "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29031, "eventname": "example 29031", "eventstate": "PROBLEM",  "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29031, "eventname": "example 29031", "eventstate": "RESOLVED", "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29030, "eventname": "example 29030", "eventstate": "RESOLVED", "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29032, "eventname": "example 29032", "eventstate": "PROBLEM",  "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29029, "eventname": "example 29029", "eventstate": "RESOLVED", "eventseverity": "High"}'
zabbix_sender -vv -z zabbix-server -s ZBUG -k event -o '{"eventid": 29032, "eventname": "example 29032", "eventstate": "RESOLVED", "eventseverity": "High"}'

Result:
See screenshot. The 'eventid' in the event name should is not the same as the tag value.

Expected:

The eventid should be the same as the tag value.

Sorry, i made a typo under 'result':

See screenshot. The 'eventid' in the event name should is not the same as the tag value.

I learned that i can use regular expressions on a single item instead of multiple dependent items to work around the problem. This way the data is always consistent, but the solution is complex not maintainable because nobody will understand the function of these regular expressions later.
