SHOW HEALTH

Note

SDK method: checkHealth.

SHOW HEALTH;

Statement	Returned columns
SHOW HEALTH	IS_HEALTHY: BOOLEAN; REASONS, QUOTA_STATES: JSON array text / VARCHAR

Use executeQuery() or execute() to read the ResultSet. This command reads server state without loading collections, flushing data or scanning entities.

IS_HEALTHY=false still returns reasons and quota states. Authentication or RPC failures raise SQLException.
