SHOW [GLOBAL|SESSION] STATUS	TiDB 数据库中 SHOW [GLOBAL|SESSION] STATUS 的使用概况。	/docs-cn/dev/sql-statements/sql-statement-show-status/ /docs-cn/dev/reference/sql/statements/show-status/

SHOW [GLOBAL|SESSION] STATUS

SHOW [GLOBAL|SESSION] STATUS 语句用于提供 MySQL 兼容性，对 TiDB 没有作用。因为 TiDB 使用 Prometheus 和 Grafana 而非 SHOW STATUS 来进行集中度量收集。
