Zabbix Housekeeping

The Zabbix Housekeeper is a background process in Zabbix that automatically manages and cleans up old data from the database to ensure optimal performance and prevent the database from growing uncontrollably.
Data Cleanup: The housekeeper deletes old data based on the configured retention periods (such as history, trends, events, and logs).
Maintains Database Size: By removing unnecessary or outdated data, it helps prevent the database from becoming too large, which could affect Zabbix’s performance.
Configurable: You can set retention periods for different types of data, like history, trends, and events. This allows you to control how long data is stored before it’s purged.
Scheduled Task: The housekeeper runs automatically at regular intervals (defined in the Zabbix configuration) to clean up the database. This task is generally performed during low-traffic periods to minimize impact on performance.
Short-Term Data (1–30 days): For event data, service data, network discovery, and autoregistration data. This data is often not needed long-term unless you're troubleshooting.
Medium-Term Data (30–90 days): History data and user session data can typically be kept for 30 to 90 days, offering a good balance between operational review and storage constraints.
Long-Term Data (365 days or more): Trend data, service data, audit logs, and trigger data (for long-term analysis) should generally be kept for a year or more if necessary for compliance or deeper analysis.
