  • Parsing log4net logs
    1 Posts | Last post January 18, 2014
    • Hi, I am trying to find a way to parse log4net logs, but cant do that via LPS. 
      I tryed to use Log Parser Lizard and there I can specify xml which describe log file format. Unfortunatly LPL not free and I can't use it after trial. Can I do something like this in LPS?
      For example I have log with such format:
      INFO  [2013-12-01 00:55:24,268] [NIT.ClientWeb.Controllers.AccountController.Login] NIT.NIT.uk is Invoked at 12/1/2013 12:55:24 AM 
      and I can describe it with xml with regex like 
      <?xml version="1.0" encoding="UTF-8"?>
      <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="C:\src\LogParserCSWebServiceInputFormat\LogParserRegexInputFormat.xsd">
                  <field name="LogType" type="String"/>
                  <field name="DateTime" type="Timestamp" format="yyyy-MM-dd HH:mm:ss,fff"/>
                  <field name="MethodName" type="String"/>             
                  <field name="Message" type="String"/>

      Title: Export Library
      Message: Could not export to PowerShell:
               Object reference not set to instance of an object.
      How to resolve this problem?

  • Application Error
    2 Posts | Last post December 11, 2013
    • Like Lazarus, I ran into this (interestingly, this did previously work).
      Backgroud thread error:one or more errors occurred.
      System.NullReferenceException: <InputFileFormatType>format returned null. The xml settings for this format may be corrupt or contain invalid entries.
      I clicked "Reset All Log Formats" in Options > Preferences. This reset my files in
      C:\Users\YourUserName\AppData\Roaming\ExLPT\Log Parser Studio\Config
      I also deleted these files and reset them.  I saw them come back after the reset.  I have tried to reinstall.  The logs work on another computer with LPS 2
    • Hi Lazarus/Diothar,
      I don't think this error can occur unless there is some permissions issue reading the config files. This of course should never happen on a normal system because all the config files are stored with in the user's profile. Additionally, if resetting them recreates them, I would think they can be read.
      I have seen this occur for one single internal user during the beta phase. I still suspect it is related to permissions and the user profile or similar. If I can repro this I can fix it but I have been unable to reproduce it thus far.
  • The specified checkpoint file is smaller than
    2 Posts | Last post December 11, 2013
    • Hello,
      I got the log parser 2.2 ran on window 2008 server for so many years.  Yesterday, the C drive was full.  After we clean and reclaim disk space, the log parser still give me an error "The specified checkpoint file is smaller than ".
      I got the file lpc file corrupted before, so I deleted the error_log.lpc but the problem still persist.
      I think about rebooting the server at mid-night.  Any idea?
    • Hi Diane,
      Check the properties for the IISW3C log type in LPS and make sure the iCheckpoint field is correct. I'm guessing it may have been previously set and the file it points to could be corrupted or the path itself is now incorrect. You might make sure it is blank and retry.
  • Advanced Logging for IIS
    2 Posts | Last post December 11, 2013
    • Hi,
      I'm using advanced logging for IIS which basically creates the same log file structure as the usual log, only with more available fields to choose from.
      I cannot use the IISW3CLOG parser because that parser assumes the existence of fields which are not part of my log.
      I tried W3CLOG by I get an error invalid cast exception (IISW3CINProperties to type W3CINProperties).
      I tried tabular separated file format, but it recognizes the "#fields" prefix as a column name, which requires me to manually edit each log file before analyzing it.
      Is there any planned support for custom fields in IIS logs?
      This is an example to the content of my file:
      #Software: IIS Advanced Logging Module
      #Version: 1.0
      #Start-Date: 2013-09-26 17:18:42.257
      #Fields:  CPU-Utilization W3WP-PrivateBytes s-port s-ip cs(User-Agent) cs-uri-stem cs-uri-query sc-status

  • Exported logs to third server
    2 Posts | Last post December 11, 2013
    • I have been using LPS, but  when I ran a query the EventCategoryName and Message, return:
      	The name for category 4 in Source "MSSQLSERVER" cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer"
      	The description for Event ID 18454 in Source "MSSQLSERVER" cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer
      I used the command wevtutil al application.evtx and put both file and the LocaleMetadata folder under LPS  log folder . But If I check with eventvwr the query return all the information. Are there another procedure to export log? Thanks for your help
    • Hi JuansH,
      This sounds like the event information needed is on the remote machine but not the machine you are running LPS from. You can confirm by opening the exported EVTX file in Windows Event Viewer on the local machine that you are running LPS on and see if you see the same message.

    • Log Parser Studio does not seem to support IIS Advanced Logging.
      Here an example query with Log Parser that does work:
      LogParser.exe "SELECT SUBSTR(s-sitename, 0, INDEX_OF(s-sitename, ',')) as [SITENAME], date, time, s-ip, sc-status FROM 'C:\LogFiles\DEFAULT WEB SITE\*.log' WHERE (sc-status >= '400' AND sc-status < '500') ORDER BY sc-status" -i:W3C -dQuotes ON -o:datagrid
      The Log Parser Studio has several issues with this.
      1. Does not allow W3C (wan't to use IIS methods)
      2. Does not allow dQuotes ON for the W3C filter
      Maybe an good idea to install IIS together with the Advanced Logging module to reproduce the issue and get it to work with the studio, unless you already got a quick fix that you can share here. :)
    • HI Joerg,
      The latest version supports IIS Advanced Logging:
