• SHOW THREADS

SHOW THREADS [ OPTION columns=width[,format=sphinxql][,format=all] ]

SHOW THREADS 是一个 SQL 语句，用于显示所有线程及其当前活动的详细信息。

返回的表格包含以下列：

TID: 由内核分配给线程的 ID
Name: 线程名称，可在 top、htop、ps 和其他进程查看工具中看到
Proto: 连接协议，可能的值包括 sphinx, mysql, http, ssl, compressed, replication，或者它们的组合（例如，http,ssl 或 compressed,mysql）
State: 线程状态，可能的值包括 handshake, net_read, net_write, query, net_idle
Connection from: 客户端的 ip:port
ConnID: 连接 ID（从 0 开始）
This/prev job time: 当线程正在工作时，显示当前任务已运行的时间；当线程空闲时，显示上一个任务的持续时间，并附加后缀 prev
Jobs done: 此线程已完成的任务数量
Thread status: idling（空闲）或 working（工作中）
Info: 查询的详细信息，如果查询目标是分布式表或实时表，可能包含多个查询

SQL:

Info 列显示的内容包括：

通过 Manticore SQL 接口执行的查询的原始文本。
使用内部 Manticore 二进制协议执行的查询（例如，从远程 Manticore 实例）时，显示查询的完整文本语法、注释及数据大小。

可以通过指定 columns=N 选项来限制 Info 列的最大宽度。

默认情况下，查询将以原始格式显示。但如果使用了 format=sphinxql 选项，查询将以 SQL 格式显示，无论执行协议是什么。

使用 format=all 将显示所有线程，而不使用此选项时，空闲线程和系统线程将被隐藏（例如，那些忙于 OPTIMIZE 的线程）。
