Overview

Dashboard snapshot of server state. Dispatches to a dialect-specific implementation that produces a uniform nested hash with four top-level sections: server, connections, innodb, queries.

On PostgreSQL the ‘innodb` section is populated with the closest equivalents (shared_buffers as buffer pool size, blks_hit/blks_read ratio as buffer pool hit rate). Lock-related fields fall back to 0 since there is no direct equivalent of InnoDB row lock waits.
