SAP's Preferred Log Reading Tool

This is the official page for the SAP Flexible Log Reader (FLR).

  • Reader for SAP BI Platform trace logs (GLFs) and any other text format
  • Very powerful search and filtering options
  • Read long chains of multiple logs at once with light memory footprint
  • Use pre-built tags to easily identify common SAP BI log messages

FLR is a log reading application which has been designed to read and analyse text log file, no matter which application has generated it. FLR is used to open large logs in any text format and can easily scan and find information within them. Typically, it is possible to open logs which total around 4.5x the available memory on the machine - e.g. a 4Gb machine can load 18Gb of logs.

FLR is one of the tools used by SAP Support Engineers to open and analyse logs in order to find further information regarding error output from SAP Products. It is more user-friendly and intuitive than other applications used to perform the same task (e.g. notepad, notepad++). Plugins and configuration files created by experts automatically analyse and tag documents for a user, flagging potential root-cause errors and other important information for ease of access. Filters and tags allow users to only scan for information relevant to the problem they are having, removing much of the need to scroll through an entire log in order to search for relevant information.

    Any news on this? The announced release date (July 2014) has passed, so I was hoping that the software would be available by now.

    Thanks.

  3. Hi,
      We are still working on one or two things to ensure that it's ready for release.

      Watch this space!

    Any news on this tool availability?

     

  5. Flexible Log reader is mentioned in many presentations or wiki/blog entries. But still not released? Any news regarding a release date?

  6. Hi,
      Thank you all for your patience.  Were in the latter stages of getting this released on SCN as its taken longer than we expected to go through the process.  The good news is that we've also been improving it further in the meantime!  I don't want to give a specific release date because I'll probably be proved wrong but were certainly getting there!

    Regards,

    hi

    i checked now.it shows no shared software.

    Michael please keep us updated..

    Thanks

  12. The version at this new link has many (around 60) improvements over the previously version, from new features to stability improvements.

    The GLF plugin now also include automatically highlighting entries highlighted as warning, errors and exceptions and, if you have a BI 4 webi log also has a section which automatically identifies specific user sessions within it so you can easily filter just the one you are interested in.  If you use the BI Support Tool (SAP BI Platform Support Tool) you can extract the rights from the system you are tracing (Tools->Export Right ID's) and put the file (call it BISupportTool<number>.csv) into the same directory as the logs, and if you have CMS tracing enabled, all the Rights checks (IsAllowed) will be enhanced with the name of the right it is checked - e.g.
       Security::IsAllowed( U=3434,R=8,Ob=8754,Own=12,T=0 ) : IsAllowed=true (from normal right)
    becomes:
      Security::IsAllowed( U=3434,R=8 (Modify the rights users have to objects),Ob=8743,Own=12,T=0 ) : IsAllowed=true (from normal right)

    Note: Right IDs can be different on different systems (see: Identifying friendly CMC Security right from a log entry complaining lack of rights) for more details

    If you are analysing an End to End trace (https://service.sap.com/sap/support/notes/1861180) you should place the BusinessTransaction.xml file in the same directory as the logs and then the GLF plugin will automatically filter the logs to just show the parts of the logs that are relevant to the End to End trace.  Previously you would be asked where it is.

    There are plenty of other things you can do with the tool, there is a plugin for Sybase ASE, java stack traces (for easily identifying which java thread is blocking other threads) etc.  There is also a configuration file for highlighting items of interest in the Business Objects Install Logs (setupengine.log)

    Hope you all find it useful!

  13. Hi Graham,

    thanks for the update. How to contact you if the link will be expired again? Will this tool be an official SAP application in the SAP marketplace? Will it be integrated in the SAP BI Support Tool?

    BR,

    Michael

     

    1. This will be put on the SCN as an official download from there.  Its gone through the legal verification but not the last stages of the SCN process.  If needed we will renew the link.

        http://service.sap.com/sap/support/notes/2203047 point to this wiki to get FlexiLogReader, but it expired again.

        Could someone please upload it ?

        Thanks

        1. Hi,
            Thanks for letting me know.  It is available again at the link at the top of the page.

          Regards,

  14. Hello,

    It is a great idea to have a tool that helps to see the logs of SAP, usually I dont use GUI tools to view logfiles but I prefer something open source  , for example you can modify  tools, like this http://lnav.org/  (open source)

     

    Sergio

    1. Hi,
        Yes, I would always recommend using whichever tool best suits the way you work.  That way you can be the most productive and get to the information you need the quickest.

      Regards,
      Graham

    Finally!!!!

    I am a big fan of this tool..... reading BO logs with Flexi log reader is like a Visiongasm.

    Its a must have for BO admins and Developers who like to follow E2E analysis for issue troubleshooting.

     

    Thanks a lot Graham

    Is there a 32 bit version available?

    1. There is not currently a 32 bit version but if there is enough demand I can create one.

      1. Dear Graham,

        It would be really handy to provide a 32-bit version of the tool. I do not want to install Java in my workstations, in order to open GLF Reader and your tool is the ideal solution.

        Thanks for your efforts. 

        Regards,

        Ilias

      2. Dear Graham,

        I can only see log files on my 32-bit workstation, i haven't access to the 64-bit server to use FLR...
        It would be very useful to have a 32-bit version ! It is possible ?
        Thank you in advance for you help !

         

  17. Link seems to be down (sad)

    1. Link is back up again.

  18. Link is down again.

    1. Former Member

      Link is valid until the 9th of January 2017. I just accessed it successfully. Can you try again?
      Edit: use the "download" link at the top in the table with various links such as the documentation, not the mdocs available in the comments

  19. Hi Graham,

    great tool! Espacially the new performance chart. I generated an E2E trace to analyze the performance of a WebI report. i found the times for HTTP, DataSources, but how to check how long WebI took to process local variables and generating the charts? Could you please give me a hint where to look or how to filter?

    Thanks in advance.

    BR,

    I'm trying to view a NetweaverDefault trace log, but all I see is a bulk text after loaded, not formatted at all to make it easier to read. Like with Timestamps and so on.

    Any suggestion is appreciated.

    Regards,

    Andras

  21. Hi Andras,
      You are correct that the NetWeaver default trace configuration file is very simple - it is designed simply to load multiple default trace files into a single view and put them in chronological order.  When they are loaded there is no special ordering.  I'll look into improving this for the next version.

    Regards,
    Graham

      Thanks Graham.

      How often is this getting an update? The time between 3.0.2 and 3.0.3 (8 months) is not very promising (smile)

  22. Any plan to support Analysis for Office log files? When i try to analyze them most of the time FLR 3.0.3 crashes.

    Regards,

    Michael

  23. I'll try to get some examples to test..

    Just wondering, is it possible to set a date/time period outside of which to exclude log entries, to help narrow down searches?

  26. Former Member

    Never mind.  Just figured out how to do it.

     

  27. Dear SAP/Developer,

    I am in love with this tool. Good Job.

    Is there in the near future an update planned? Regardless version 3.0.2 or 3.0.3 or Windows Version the tool crashes sometimes.

     

    Cheers

    1. Update: Tool version 3.1 fixes wont crash

      1. Where did you get FLR 3.1? I cannot find it.

        1. Dear Michael,

          I got this via an opened Incident regarding the crashes.

          I recommended that this space needs an update.

          Cheers

        2. Hi,

            I've made this new version available to all now.  See the download link near the top of the page

          Thanks,

          Graham
