Lost events
Study Notes
Autoregistration in Zabbix 6.0
- HostInterface parameter allows custom value for the host interface, useful for monitoring added hosts with passive checks
- Autoregistration action attempt happens every time an active agent updates configuration, at least one autoregistration action must be enabled
- Autoregistration is executed when a previously unknown active agent asks for a configuration, when host metadata information changes, or when action operations are changed
- Autoregistration action conditions include host name, metadata match, contains, proxy, and type of calculation
- Autoregistration action operations include add/remove host, assign/unassign host group, link/unlink templates, send message, remote command, enable/disable host, and set host inventory mode
- Autoregistration is set up by defining matching action conditions, operations, and configuring Zabbix Agent in active mode with optional parameters
- Autoregistration of passive checks is supported, allowing autoregistered hosts to be monitored using passive checks
- Secure autoregistration is possible by configuring PSK-based authentication, with options for no encryption, PSK authentication only, or both modes
- Practical setup involves setting up PSK auto-registration options, creating an "Auto registration" action, configuring the agent, and checking the hosts for registered agents
- PSK identity and key are used for setting up PSK auto-registration options
- An "Auto registration" action is created with conditions for host metadata match and linking a template
- Practical task involves checking the "Hosts" for the registered agents and fixing encryption settings for the previously created hosts
