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。对于大部分监控指标，TiDB 使用 Prometheus 和 Grafana 来集中收集，而不是使用 SHOW STATUS。

该语句输出中各变量的详细介绍，请参考服务器状态变量。
