17 Service monitoring upgrade

    This page describes how services and SLAs defined in earlier Zabbix versions are changed during an upgrade to Zabbix 6.0 or newer.

    If a service “Child service” was previously linked to “Parent service 1” via hard dependency and additionally “Parent service 2” via soft dependency, after an upgrade the “Child service” will simply be linked to two parent services (“Parent service 1” and “Parent service 2”).

    Status calculation rules

    • Do not calculate → Set status to OK
    • Problem, if all children have problems → Most critical if all children have problems

    If you have upgraded from Zabbix pre-6.0 to Zabbix 6.0.0, 6.0.1 or 6.0.2, see for Zabbix 6.0 documentation.

    During an upgrade:

    • Identical SLAs defined for each service will be grouped and one SLA per each group will be created.
    • Service creation time, which is a new metric used in SLA reports, will be set to 01/01/2000 00:00 for existing services.
