Question

我正在支持偶尔出现性能问题的应用程序。客户想知道页面的播放频率。

即。页面占用的总时间大于x秒/页面请求总数

我想写一个查询来获取所需的数据。

SQL中的这样的东西可能会起作用，但在IIS Log解析器中不起作用。

select URL, count(case when time > 100  then 1 else null end), count(*)
from   table1
group by URL

Answer 1

这里的问题是你需要两个查询。

无论花费多少时间，都要计算每页请求的总数

SELECT cs-uri-stem, COUNT(*) AS all-requests 
FROM ex*.log 
GROUP BY cs-uri-stem

一个计算时间拍摄的页数＆gt; X秒

SELECT cs-uri-stem, COUNT(*) as total-requests
FROM ex*.log
WHERE time-taken > 1000 <- time_taken is milliseconds
GROUP BY cs-uri-stem

您所需的结果需要加入：

SELECT a.cs-uri-stem, COUNT(*) as total-requests, b.all-requests
FROM ex*.log AS a
JOIN (
    SELECT cs-uri-stem, COUNT(*) AS all-requests 
    FROM ex*.log 
    GROUP BY cs-uri-stem
) AS b ON b.cs-uri-stem = a.cs-uri-stem
WHERE a.time-taken >1000 
GROUP BY a.cs-uri-stem

不幸的是，LogParser中没有对JOIN的支持。

您可以做的是将两个查询的结果导入SQL数据库并在那里运行查询：

SELECT a.cs-uri-stem, COUNT(*) as total-requests, b.all-requests
FROM long_running_pages AS a
JOIN all_pages_grouped b ON ( a.cs-uri-stem = b.cs-uri-stem)
GROUP BY a.cs-uri-stem

IIS Log Parser - 需要查询以查找按URL分组的“请求总数> x秒”/“总请求数”
