I'm attempting to build nxlog with some updated libraries: Latest APR (1.5.2) Non-Heartbleed vulnerable OpenSSL sources PCRE 8.37 Zlib 1.2.8 After building all the dependencies I'm a little stuck on getting nxlogs to build, specifically I'm stuck on the step where I run ./configure At first it couldn't find apr-1-config, so I added /local/apr/bin to the path. Then it couldn't fine libapr-1 so I added /local/apr/lib to the path, this is where the problems started. When APR built there wasn't a "libapr-1" file in /local/apr/lib, only libapr-1.a, libapr-1.la, libapr-1.dll.a. Did I build APR incorrectly? I'm trying to build this on windows List of steps to get where I am: 1. Install MINGW using MinGW Installation Manager Add packages: mingw-developer-toolkit mingw-base mingw-expat bin mingw32-libexpat dev msys-libopenssl dev msys-automake msys-autoconf Setup msys fstab (c:/mingw     /mingw) 2. Install Python (2.5) 3. Add Python and mingw to system path (C:\Python25;C:\MinGW\bin;C:\MinGW\msys\1.0\bin) 3. Get and build APR source (I could not get APR iconv to compile) Download: http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.11.tar.gz http://mirror.nexcess.net/apache//apr/apr-1.5.2-win32-src.zip http://mirror.nexcess.net/apache//apr/apr-util-1.5.4-win32-src.zip http://sourceforge.net/projects/pcre/files/pcre/8.37/pcre-8.37.zip/download http://zlib.net/zlib128.zip Build: Extract all files to c:\mingw\msys\1.0\src Compile libiconv cd libiconv-1.11 ./configure CFLAGS="-O2 -s -mms-bitfields -march=i686" CXXFLAGS="-O2 -s -mms-bitfields -march=i686" make && make install Compile APR cd apr ./buildconf   ./configure CFLAGS="-O0 -s -mms-bitfields -march=i686" CXXFLAGS="-O0 -s -mms-bitfields -march=i686" make && make install cd ..

Fixed by adding /local/apr/bin to path. Now it can't find libapr-1, addint /local/apr/lib to the path doesn't help. There is no libapr-1 file in the MinGW directory tree. Ideas?   -pacmanwa  

Hi, When the nxlog is already started and the logfile is yet to be created by the application, I see "WARNING input file does not exist" message in nxlog.log file. How often does nxlog service retry\check for missing files which are created after starting nxlog service? Thanks & Regards, Mohan Guttikonda

Hy, I need some help in configuring my nxlog in windows XP. System: S.O. -> windows XP NXLOG Version -> 2.8.1248 LOGS: We use a log file for each event and these log files are stored in an hierarchical directory as: f:\year\month\day\accxxxx.txt (e.g. f:\2015\09\03\event000001.txt) ​ nxlog.conf excerpts: <Extension multiline>     Module xm_multiline     HeaderLine '<?xml version="1.0" encoding="UTF-8" standalone="yes"?>' </Extension> <Input in>     Module       im_file     File         'E:\\hl7\\' + strftime(now(),"%Y\\\\%m\\\\%d") + '\\AccEvent*.txt'     SavePos      TRUE     ReadFromLast TRUE     PollInterval 15     Recursive    TRUE     InputType    multiline </Input> I tested these cases: 1. (service nxlog active), add new file in  f:\2015\09\03\-> nxlog find the new file and analyze [OK] 2. Stop service nxlog, add new file in f:\2015\09\03\, start service -> nxlog don't find the new file. [X] 3. (service nxlog active), rename a file  in f:\2015\09\03\ already analyzed -> nxlog find the file renamed and analyze (in the log warning input file deleted) [OK] 4. (service nxlog active), update an existing file (same name, change only datetime last modified) -> nxlog don't analyze [OK] I need to resolve step 2. If I set ReadFromLast =FALSE when I restart service all fiels are all analyzed and that is not the desiderata.   Thanks in advance for your help. Dario  

Hello, I think this is an easy answer, but I am having some issues.  I am trying to read in a log file and send out a syslog message.  If the line in the file contains the word error, I want a syslog message to be sent.  If the file does not contain that word, just drop the message.  What would be the proper way to do this?  Below is what I currently have.   <Input watchfile_%service%>   Module im_file   File '%servicepath%'   Exec $Message = $raw_event;   Exec $SyslogSeverityValue = 6;   Exec if file_name() =~ /.*\\(.*)/ $SourceName = $1;    Exec if $raw_event =~ /ERROR/ $SyslogSeverityValue = 3;    SavePos TRUE     Recursive TRUE   PollInterval 10 </Input> Thank You

Hi, I am trying to read multiline xml files (results of ELMAH logs in ASP.NET), but for some of them I am unable to do so, as they contain lots of information. This results in errors like this: 2015-09-02 08:50:50 ERROR data size (119671) is over the limit (65000), will be truncated I tried googling for a resolution to this problem, but I couldn't find any information anywhere about a data size limit in nxlog. Could some please advise what I could do to fix this?

Hello, Recently, i ran into a problem with file locking. One application here is generating some log file, one per client, when nxlog try to read file, i got error : ERROR failed to open LOGFILEPATH; Le processus ne peut pas accéder au fichier car ce fichier est utilisé par un autre processus. Initaly my configuration was : <Input Orbis>     Module im_file     File 'LogDirectory\\*'     SavePos TRUE     ReadFromLast FALSE     CloseWhenIdle TRUE     InputType orbisLog     Exec if $raw_event !~ /^L:.*/  drop();     Exec $ClientNAme = replace(file_basename(file_name()),'.LOG',''); </Input> I have changed the PollIntervall to 60 and 3600, no effect... Except that at PollInterval 3600, nxlog grab 40% of CPU. Is there a way to insctruct nxlog to retry to read the file ?

Hi , I am trying to compile nxlog on solairs 11 sparc platform.

Thanking you with regards.    

Hello, I'm quite new to nxlog, so forgive me if my question is  trivial but I'm having hard time to get the values I extract from my  logs using exec and a regex. I have a very large stash of old windows logs in text file (in multiline format), what I want to do is use nxlog to load them in graylog, but I want to format the log in a different way. It works perfectly when I do not use the the exec and the regexp, but it fails with the message: 2015-08-31 12:12:42 ERROR invalid keyword: $timestamp at C:\Program Files (x86)\nxlog\conf\nxlog.conf:36 The regex works when I test it using http://www.regexr.com/ The error seems in the way I'm trying to assign/write the variables matched by the regex   My nxlog.conf is like the below: ## This is a sample configuration file. See the nxlog reference manual about the ## configuration options. It should be installed locally and is also available ## online at http://nxlog.org/nxlog-docs/en/nxlog-reference-manual.html ## Please set the ROOT to the folder your nxlog was installed into, ## otherwise it will not start. #define ROOT C:\Program Files\nxlog define ROOT C:\Program Files (x86)\nxlog Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data LogFile %ROOT%\data\nxlog.log <Extension gelf>     Module       xm_gelf </Extension> <Extension multiline>     Module      xm_multiline     HeaderLine  /^{/     EndLine     /^}/ </Extension> <Input in>         Module  im_file         File    "C:\\tmp\\\\example-log.txt"         SavePos  TRUE         Recursive TRUE         InputType       multiline         exec if $raw_event =~ /(?:\{"([0-9]+?), ([0-9]+?), "(.+?)", "(.+?)", "(?:.+?)","(.+?)\n(?:[a-zA-Z0-9:,"\n\r\s\f\t\-\{\}\.\(\)]+?)New\sLogon:\s*(?:.+?)\n\s*Account\sName:\s*(.+?)\n(?:[a-zA-Z0-9:,"\n\r\s\f\t\-\{\}\.\(\)]+?)Source\sNetwork\sAddress:\s*([0-9\.]{7,15})\n(?:[a-zA-Z0-9:,"\n\r\s\f\t\-\{\}\.\(\)]+?)"\})/g;            $timestamp = $1;      $event = $2;      $status = $3;      $type = $4;      $short = $5;      $user = $6;      $source = $7;       </Input> #<Output out> #    Module      om_tcp #    Host        192.168.1.15 #    Port        12201 #    OutputType  GELF_TCP #</Output> <Output out>     Module    om_file     File    'C:\\tmp\\output' </Output> <Route 1>     Path        in => out </Route>    Could someone kindly help me out on this? I tried to read the nxlog manual but I need to confess that I could not understand what I'm doing wrong  Basically I just would the output to be composed by the raw message and the few fields I match with the regex   Thanks very much!   Mark

I've got some data that comes in with a somewhat unusual format.  It's a set of fixed fields, followed by a variable length set of keys, followed by a set of values.  It looks something like this (but with more fields): col1, col2, col3, description(key1; key2; ...;keyn), val1, val2, ..., valn I'm trying to transform this into something more like: a=col1, b=col2, c=col3, key1=val1, key2=val2, ..., keyn=valn I've actually got this working by using Exec and a bit of perl that I wrote that tears apart $raw_event and writes the modified logline to a domain socket, where a second instance Route is listening and sends the log over the network to its destination.  My problem is that this is not terribly performant, since it starts a perl process per log line.  I've had trouble figuring out another way to do this, mostly because the number of keys/values is variable. Any suggestions on ways this might be done that are likely to have better performance?

Hello there! I am using nxlog for tailing specific files (im_file) and output them via GELF_TCP to Graylog which goes good except 1 thing > short_messages get truncated to 64 chars which, if I understand right, is related to this directive (or I might be wrong): ShortMessageLength >This optional directive can be used to specify the length of the short_message field. This defaults to 64 if the directive is not explicitly specified. If the field short_message or ShortMessage is present, it will not be truncated. The question might be fairly simple (to someone who knows): how to use this directive? could someone please write an example how to use it so short_messages do not get truncated? Many thanks in advance! P.S. Same problem here > https://groups.google.com/forum/#!topic/graylog2/wUQIaFdUlZs

I have a client who wants to use Loggly with NXLOG using UNC Paths to shared servers instead of absolute paths but has hit a road block. Instead of using something like this: C:\files\logs\mylog.txt He wants to do something like this: \\computername\windowsshare\c$\mylog.txt When he has the nxlog service set to Local System and points to an absolute path to a local file it works fine. But when he changes the service to be running as a Domain User and then sets his UNC path in the config file he gets an access denied error. He has demonstrated that that Domain User has access to the file by logging in as that user and then opening the path to the file. FYI, he has found that putting \\ in the config file causes problems but using \\\ seems to work. Thanks. -Bill

Greetings, I'm trying to filter event viewer logs by the source name using the following configuration: <Input EventLog>     Module      im_msvistalog     Query       <QueryList>\                     <Query Id="0">\                         <Select Path="Application">*</Select>\                         <Select Path='System'>*[System[(SourceName="Service Control Manager")]]</Select>\                     </Query>\                 </QueryList> </Input>   However it's not working. When I try and filter by Event ID that works no problem. Any assistance would be much appreciated.  

Hi, I have several routes, outputs, and inputs and would like to have a schedule block that effects all logs. Is this possible? My current implementation is to put the schedule block in each Output. It works, but I was seeing if there was a way to clean it up and get it into one scheduler. Thank you!
