v.22.4New Feature

Added Sanity Checks on Server Startup

Added sanity checks on server startup (available memory and disk space, max thread count, etc). #34566 (Sergei Trifonov).
Added sanity checks on ClickHouse server startup to verify available memory, disk space, maximum thread count, and other critical system parameters.

Why it matters

This feature ensures that the ClickHouse server environment meets minimum resource requirements before starting, preventing operational issues caused by insufficient memory, disk space, or inappropriate thread settings. It improves server reliability and early error detection for users.

How to use it

The sanity checks are automatically performed when the ClickHouse server starts. Users do not need to enable anything explicitly; the server will validate system resources and configurations before fully launching.
