SQL 响应时间的等效 PerfMon 计数器是多少？

Question

SQL 响应时间的等效 PerfMon 计数器是多少？请查看图片以获得更多说明。

我已经发布了资源监视器的计数器。我希望在 Grafana 中显示 SQL 响应时间 （最后一个 coulmn）的等效 PerfMon 计数器。

下面的 DMV 查询将报告自 SQL 实例上次启动以来每个文件的 IO 统计信息，并计算平均总计读取和写入响应时间。

WITH io_stats AS (
    SELECT
          mf.physical_name
        , vfs.NumberReads + vfs.NumberWrites AS NumberTotal
        , vfs.IoStallReadMS + vfs.IoStallWriteMS AS IoStallTotalMS
        , vfs.NumberReads
        , vfs.IoStallReadMS
        , vfs.NumberWrites
        , vfs.IoStallWriteMS
    FROM sys.master_files AS mf
    CROSS APPLY sys.fn_virtualfilestats(database_id, file_id) AS vfs
)
SELECT
      physical_name
    , NumberTotal
    , IoStallTotalMS
    , IoStallTotalMS / CASE WHEN NumberTotal = 0 THEN NULL ELSE NumberTotal END AS ResponseTime
    , NumberReads
    , IoStallReadMS
    , IoStallReadMS / CASE WHEN NumberReads = 0 THEN NULL ELSE NumberReads END AS ResponseTimeRead
    , NumberWrites
    , IoStallWriteMS
    , IoStallWriteMS / CASE WHEN NumberWrites = 0 THEN NULL ELSE NumberWrites END AS ResponseTimeWrite
FROM io_stats;

SQL 响应时间的等效 PerfMon 计数器是多少？

What will be equivalent PerfMon counters for SQL Response Time?

sql-server

perfmon
