Log Parser Lizard

Özellikle IIS Loglarını analiz edebileceğiniz şahane bir araç. Log Parser Lizard

Öncelikle  Log Parser 2.2  ı indiriyoruz. Log Parser 2.2  Klasik kurulum sonrasında

C:\Program Files (x86)\Log Parser 2.2>regsvr32 LogParser.dll  komutu ile LogParser.dll  i alıyoruz.

Log Parser Lizard http://www.lizard-labs.com/log_parser_lizard.aspx  uygulamasını kuruyoruz. Almış olduğumuz IIS .log ve httperr loğlarını uygulama üzerinden açarak çalışmaya başlayabiliyoruz.

Örnek 1: 10 ar dakikalık ara ile alınan 404 hatalarının sayısı.

SELECT TO_LOCALTIME(QUANTIZE(TO_TIMESTAMP(date, time), 600)) AS ZamanDilimi, count(*) FROM C:\Temp\IIS\LogData\*.log where time > ’09:00:00′ and sc-status = 404                          group by ZamanDilimi

Bazı Mesajlar ve Anlamları:

Reason Phrase Description
AppOffline A service unavailable error occurred (an HTTP error 503). The service is not available because application errors caused the application to be taken offline.
AppPoolTimer A service unavailable error occurred (an HTTP error 503). The service is not available because the application pool process is too busy to handle the request.
AppShutdown A service unavailable error occurred (an HTTP error 503). The service is not available because the application shut down automatically in response to administrator policy.
BadRequest A parse error occurred while processing a request.
Client_Reset The connection between the client and the server was closed before the request could be assigned to a worker process. The most common cause of this behavior is that the client prematurely closes its connection to the server.
Connection_Abandoned_By_AppPool A worker process from the application pool has quit unexpectedly or orphaned a pending request by closing its handle.
Connection_Abandoned_By_ReqQueue A worker process from the application pool has quit unexpectedly or orphaned a pending request by closing its handle. Specific to Windows Vista and later versions and to Windows Server 2008 and later versions.
Connection_Dropped The connection between the client and the server was closed before the server could send its final response packet. The most common cause of this behavior is that the client prematurely closes its connection to the server.
Connection_Dropped_List_Full The list of dropped connections between clients and the server is full. Specific to Windows Vista and later versions and to Windows Server 2008 and later versions.
ConnLimit A service unavailable error occurred (an HTTP error 503). The service is not available because the site level connection limit has been reached or exceeded.
Connections_Refused The kernel NonPagedPool memory has dropped below 20MB and http.sys has stopped receiving new connections
Disabled A service unavailable error occurred (an HTTP error 503). The service is not available because an administrator has taken the application offline.
EntityTooLarge An entity exceeded the maximum size that is permitted.
FieldLength A field length limit was exceeded.
Forbidden A forbidden element or sequence was encountered while parsing.
Header A parse error occurred in a header.
Hostname A parse error occurred while processing a Hostname.
Internal An internal server error occurred (an HTTP error 500).
Invalid_CR/LF An illegal carriage return or line feed occurred.
LengthRequired A required length value was missing.
N/A A service unavailable error occurred (an HTTP error 503). The service is not available because an internal error (such as a memory allocation failure or URL Reservation List conflict) occurred.
N/I A not-implemented error occurred (an HTTP error 501), or a service unavailable error occurred (an HTTP error 503) because of an unknown transfer encoding.
Number A parse error occurred while processing a number.
Precondition A required precondition was missing.
QueueFull A service unavailable error occurred (an HTTP error 503). The service is not available because the application request queue is full.
RequestLength A request length limit was exceeded.
Timer_AppPool The connection expired because a request waited too long in an application pool queue for a server application to de-queue and process it. This time-out duration is ConnectionTimeout. By default, this value is set to two minutes.
Timer_ConnectionIdle The connection expired and remains idle. The default ConnectionTimeout duration is two minutes.
Timer_EntityBody The connection expired before the request entity body arrived. When a request clearly has an entity body, the HTTP API turns on the Timer_EntityBody timer. At first, the limit of this timer is set to the ConnectionTimeout value (typically, two minutes). Every time that another data indication is received on this request, the HTTP API resets the timer to give the connection two more minutes (or whatever is specified in ConnectionTimeout).
Timer_HeaderWait The connection expired because the header parsing for a request took more time than the default limit of two minutes.
Timer_MinBytesPerSecond The connection expired because the client was not receiving a response at a reasonable speed. The response send rate was slower than the default of 240 bytes/sec. This can be controlled with the MinFileBytesPerSec metabase property.
Timer_ReqQueue The connection expired because a request waited too long in an application pool queue for a server application to de-queue. This time-out duration is ConnectionTimeout. By default, this value is set to two minutes. Specific to Windows Vista and later versions and to Windows Server 2008 and later versions.
Timer_Response Reserved. Currently not used.
Timer_SslRenegotiation The connection expired because SSL renegotiation between the client and server took longer than the default time-out of two minutes.
URL A parse error occurred while processing a URL.
URL_Length A URL exceeded the maximum permitted size.
Verb A parse error occurred while processing a verb.
Version_N/S A version-not-supported error occurred (an HTTP error 505).

Use the Page File Bytes Peak counter to calculate page file size

  1. Click Start, point to Administrative Tools, and then click Performance Monitor.
  2. Expand Data Collector Sets, right-click User Defined, click New, and then click Data Collector Set.
  3. In the Name box, type a name for the log, and then click OK.
  4. Select the Create manually (advanced)option, and then click Next.
  5. Select the Create data logsoption, click to select the Performance counter check box, and then click Next.
  6. Under Which performance counters would you like to log?, click Add.
  7. Under Select counters from computer, make sure that <Local computer>
  8. In the Performance object list, click Process, and then click Page File Bytes Peak.
  9. Under Instances of selected object, select Total, click Add>>, and then click OK.
  10. Under Sample interval, select the interval that you want. (The default is 15 seconds.)
  11. Click Next two times.
  12. Click Finish.
  13. Let the counter run during typical use of your computer.

 

Note the maximum value for the Page File Bytes Peak counter, and then multiply the value by 0.70. The sum of the equation is the size to set for your page file.
