The dashboard now supports displaying metrics across different ClickHouse versions even if the structure of system tables has changed after an upgrade.

Why it matters

This feature solves the issue of inconsistent or missing metrics in the dashboard when ClickHouse is upgraded and system table structures change. It ensures continuity and reliability of monitoring data across different versions, enhancing observability and troubleshooting.

How to use it

No specific user action is required. The dashboard automatically adapts to changes in system table structures across ClickHouse versions, allowing seamless viewing of metrics without additional configuration.
