SQL Log File Viewer Q - Does it Sometimes Drop Records

  • Had a rather odd problem this morning wth the SQL Log Viewer. At first when I looked at it the viewer was showing a gap of 3 hours in the record where one record has date/time stamp of 10/26/2010 200AM and the very next one has a Date/Time stamp of 10/26/2010 505AM; a 3 hour gap. At firts I thought something happened and the system was down for 3 hours but when I looked at the Windows Logs I found SQL Logins being recorded during this same 3 hour period. I went back to the SQL Log Viewer and low and behod the thing no longer has a 3 hour gap in it.

    Has anyone else had odd results like with this the Log Viewer? Is the built in Log Viewer picky or finicky? Perhpas not the best tool to use for veiwing the log?

    Kindest Regards,

    so after that I started using undocumented sp_readerrorlog which also allows you to search error logs.

    Here is the syntax for it.

    CREATE PROC [sys].[sp_readerrorlog](

    @p1 INT = 0,

    @p2 INT = NULL,

    @p3 VARCHAR(255) = NULL,

    @p4 VARCHAR(255) = NULL)

    AS

    BEGIN

    IF (NOT IS_SRVROLEMEMBER(N'securityadmin') = 1)

    BEGIN

    RAISERROR(15003,-1,-1, N'securityadmin')

    RETURN (1)

    END

    IF (@p2 IS NULL)

    EXEC sys.xp_readerrorlog @p1

    ELSE

    EXEC sys.xp_readerrorlog @p1,@p2,@p3,@p4

    END

  • If you want to do stuff properly and reliably with the tlog, get a copy of ApexSQL's log tool(s).
