Log Parser And IIS Log Analysis.

  • [アーティクル]

First have  Log Parser installed. Then Start it from C:\Program Files (x86)\Log Parser 2.2 

Here are some Log Parser queries which can be used across  IIS logs for analysis

Request Type Distribution

"SELECT EXTRACT_EXTENSION(TO_UPPERCASE(cs-uri-stem)) AS ExtType, COUNT(*) INTO FrontEndRequestType.csv FROM *.log GROUP BY ExtType ORDER BY COUNT(*) DESC " -i:W3C -o:CSV

 

Top 20 Hits

"SELECT TOP 20 TO_UPPERCASE(cs-uri-stem) AS URI, COUNT(*) AS Hits INTO Top20Hits.csv FROM *.log WHERE URI LIKE '%%.ASPX' GROUP BY URI ORDER BY Hits DESC " -i:W3C -o:CSV

 

Top 20 Hits Overall

"SELECT TOP 20 TO_UPPERCASE(cs-uri-stem) AS URI, COUNT(*) AS Hits INTO Top20Hits.csv FROM *.log GROUP BY URI ORDER BY Hits DESC " -i:W3C -o:CSV

 

Top 20 Hits Chart

"SELECT TOP 20 cs-uri-stem, max(time-taken) as MaxTime, avg(time-taken) as AvgTime INTO Top20SlowASPX.csv FROM *.log WHERE extract_extension(to_lowercase(cs-uri-stem)) = ‘aspx’ GROUP BY cs-uri-stem ORDER BY MaxTime DESC" -i:W3C -o:CSV

 

Top 20 ASMX Hits

"SELECT TOP 20 TO_UPPERCASE(cs-uri-stem) AS URI, COUNT(*) AS Hits INTO Top20ASMX.csv FROM *.log WHERE URI LIKE '%.ASMX' GROUP BY URI ORDER BY Hits DESC " -i:W3C -o:CSV
