9 Upgrade notes for 4.4.0

Zabbix 4.4.0 is not released yet.

Changed host export format

The format of host and template export has been changed in the way how triggers are exported. Previously all triggers were listed after the host information. Now, to achieve better readability, triggers that are based on one host item only in problem and recovery expression are listed within tags of the respective host item.

Note also how the expression of the triggers does not reference the host or item, but only the function ({last()}<>0 in the example):

    <hosts>
        <host>
            <host>Host</host>
            ...
            <items>
                <item>
                    <name>Item</name>
                    <type>0</type>
                    <snmp_community/>
                    <snmp_oid/>
                    <key>item.key</key>
                    ...
                    <triggers>
                        <trigger>
                            <expression>{last()}<>0</expression>
                            <recovery_mode>0</recovery_mode>
                            <recovery_expression/>
                            <name>Item value not 0</name>
                            <correlation_mode>0</correlation_mode>
                            <correlation_tag/>
                            <url/>
                            <status>0</status>
                            <priority>2</priority>
                            <description/>
                            <type>0</type>
                            <manual_close>0</manual_close>
                            <dependencies/>
                            <tags/>
                        </trigger>
                    </triggers>
                </item>
            </items>
        </host>
    </hosts>

The same change affects simple trigger prototypes that are placed under <item_prototype><trigger_prototypes>.

However, triggers that are more complex and contain several host items are listed within separate <triggers> tags, as before.

Items table split

Realtime fields have been split from the items table into a new table called item_rtdata. See also What's new in 4.4.0.
