Study Notes

Zabbix High Availability (HA) Configuration and Management

Zabbix HA supports automatic failover with nodes reporting status every 5 seconds
The standby node takes over when the active node shuts down or becomes unreachable
Runtime commands can adjust cluster parameters, such as failover delay and removing nodes
Zabbix can be set up in HA mode by starting Zabbix server on all nodes and configuring network devices
Practical setup involves defining HANodeName and NodeAddress, using Podman container engine, and managing the HA cluster
Zabbix proxies collect monitoring data on behalf of Zabbix server and preprocess data if required
Proxies receive monitoring configuration from Zabbix server and send collected data to the server
Zabbix proxies are a reliable way to monitor distributed IT infrastructure, running custom scripts and offloading server resources
Zabbix frontend centrally manages all proxies, controlling monitoring configuration and supporting various OS platforms and DB engines
Proxies use a database as a buffer for communication problems, with options to save data for up to 30 days
Zabbix supports different database engines on the server and proxies, with options to store data locally even after syncing with the server
