What is the purpose of Zabbix's Housekeeper feature?

The Housekeeper feature in Zabbix is designed primarily to manage and remove expired data. Its main function is to ensure that the database remains efficient and performance-driven by deleting unnecessary or outdated data that is no longer required for monitoring or historical analysis. By regularly cleaning up expired data, the Housekeeper helps maintain optimal database size and performance, which can improve overall system efficiency and responsiveness.

This process is particularly important in environments with significant amounts of monitored metrics, as accumulated historical data can lead to increased storage requirements and slower queries over time. By removing this data, the Housekeeper contributes to the smooth operation of Zabbix, ensuring that only relevant and useful data is retained for current monitoring needs. Additionally, this maintenance operation helps in minimizing potential database bloat, which can impact the performance of queries and data retrieval.

Maintaining an efficient database through the Housekeeper feature is a crucial aspect of Zabbix’s capabilities, enabling users to focus on active monitoring and analysis rather than being bogged down by obsolete data.
