全页展开

语法

mps-status [-C [path/]server_name][--statistics|-s [sample_interval]] [--json|-j]

描述

mps-status [-C [path/]server_name][--statistics|-s [sample_interval]] [--json|-j] 显示服务器（STARTED、STOPPED）的状态以及服务器实例的完整路径。此外，它还可以显示有关服务器的性能统计数据，包括：

  • 采样间隔（以毫秒为单位）

  • CPU 利用率

  • 活跃工作进程进程数

  • 队列中的请求数

  • 内存使用量

  • 每秒请求吞吐量

  • 总排队时间（以毫秒为单位）

输入参数

-C path/

指定服务器实例的路径。如果省略此选项，则搜索当前工作文件夹及其父文件夹来查找服务器实例。

server_name

需要查询状态的服务器

--statistics [sample_interval], -s [sample_interval]

指定要收集并显示的统计数据。

可选的 sample_interval 允许您指定收集统计信息的间隔（以毫秒为单位）。默认值为 500。

注意

如果指定采样间隔为 0，则仅进行一次采样。需要两个样本来计算一些统计数据，例如 CPU 利用率和吞吐量。

--json, -j

指定统计信息以 JSON 格式输出：
