Study Notes

Zabbix 6.0 Certified Professional Day 2 Training Summary

Zabbix 6.0 introduces context-based macros in user macros to allow overriding default values for different conditions.
Context-based macros can be created on a template, host, or global level, extending the user macro with the context to match different conditions.
Context macros can be used in triggers to accomplish more flexible thresholds in trigger expressions based on the values retrieved by Low-level Discovery.
A practical setup for context-based macros involves creating new macros and trigger prototypes, executing file systems discovery rules, and resolving problems.
Zabbix 6.0 introduces specific Low-level Discovery (LLD) keys for Linux systemd services, which can be discovered using Zabbix agent 2 and return data in JSON format.
LLD macros are used in prototypes to discover Linux systemd services, and examples of systemd keys are provided.
Zabbix agent can discover Windows services using LLD, returning data in macros like service name, display name, description, state, startup type, and more.
LLD for WMI queries in Zabbix is done using WQL queries, which are automatically transformed into a JSON object for discovery.
The Zabbix 6.0 documentation provides detailed information on the usage of context-based macros, LLD for Linux systemd services, Windows services, and WMI queries.
