Study Notes
Zabbix 6.0 Certified Professional Day 3: Event Correlation
- The graph prototype displays used and predicted size and time left
- Context-based macros are used to update the trigger prototype
- Event correlation in Zabbix allows for the correlation of problem events to their resolution
- Trigger-based event correlation utilizes tags to extract values and create identification for problem events
- Actual tags and tag values only become visible when a trigger fires
- Problem recovery settings include the host name in a tag for matching
- Global event correlation in Zabbix allows for correlations across all monitored metrics
- Important safety tips for global event correlation include setting unique tags and limiting the number of correlation rules
- Global event correlation rules can be configured in the Zabbix interface under "Event correlation"
- Global event correlation conditions are based on "new" and "old" events and include multiple conditions for matching
- Global event correlation actions include closing old events and new events, with specific operations defined for each
- The text includes timestamped entries related to accepting and denying incoming connections on specific IP addresses
