Better Information Messages About Lack of Linux Capabilities

Why it matters

This feature addresses the problem of insufficient visibility when required Linux capabilities are absent by logging fatal errors at a higher severity level. This helps users quickly identify and diagnose capability-related issues in ClickHouse through easier log filtering and monitoring.

How to use it

No explicit user action is required to enable this feature. The enhanced fatal-level error logging for missing Linux capabilities is applied automatically, and users can monitor these errors by querying the system.text_log table.
