[2.4.0] Checkmk Werk 16712 created: Changed format of host tag conditions in alert_handlers.mk configuration file

[//]: # (werk v2) # Changed format of host tag conditions in alert_handlers.mk configuration file key | value ---------- | --- date | 2024-06-10T08:36:41+00:00 version | 2.4.0b1 class | feature edition | cee component | setup level | 1 compatible | yes The internal data format of the Checkmk alert handler rule definitions, normally configured via Setup "Alert handlers" page, has been changed. If you only use Setup for configuring Checkmk this change will not be relevant for you, since the data format will be changed automatically during update to 2.4x. In case you edit alert_handlers.mk files manually or via script to define the <tt>alert_handler_rules</tt> configuration options, you will likely have to change your scripts or at least the configuration files. An alert handler rule definition with it's tag conditions in the old format looks like this: F+:alert_handlers.mk alert_handler_rules += [ { "description": "Rule description", ..., "match_hosttags": ["my-host|cmk-agent|prod|lan|piggyback|no-snmp"], ..., } ] F-: The tags that should match are in list format, separated via pipe characters. There is no information about the tag group the configured tag is related with. The new structure looks like this: F+:alert_handlers.mk: alert_handler_rules += [ { "description": "Rule description", ..., "match_hosttags": { "agent": "cmk-agent", "criticality": "prod", "networking": "lan", "piggyback": "piggyback", "snmp_ds": "no-snmp", }, ..., } ] F-: In the <tt>alert_handler_rules</tt> dictionary the keys are the tag groups (as defined in Setup) and the values are the tags configured for each group.
