i have looked on the avail;able docs but have not yet seen such an example, is there a way to convert IPs to dns names, given the message below how to replace 192.168.225.2 with its dns name, host.name.com? <132>Sep 22 20:24:01 qare RouteAnalyzer[21700]: Prefix 192.168.42.64/32 (192.168.42.64/32) from router 192.168.225.2 in BGP/AS64512 went down.Configured thanks.

Is there a command or switch to prevent nxlog from deleting log files that have already been consumed and forward to their destination? I am want to forward the Exchange 2013 Message Tracking logs to a Graylog Server but need to leave the tracking logs in place. Thanks, Dan

Hi, Below patch enables NXLog to correctly skip UTF-8 BOMs in RFC5424 syslog messages. Should I also log a support ticket for this?

xm_perl.so is missing from the nxlog-ce-2.8.1248.tar.gz. this is causing nxlog to file. Is there any package with this missing file? I appreciate your help. Thank You.

I am trying to use the multlog module in order to start ingesting a custom log: I have the following regex: \^(\d{2}|\d).(\d{2}|\d).(\d{4})\s(\d\d|\d):(\d\d|\d):(\d\d|\d)\s(AM|PM).\[(.*)\](.*) This works in a regex test; however I cannot get it to work with the log file that looks something like this 9/10/2015 11:29:16 AM [0-3-1-SecondaryPortStatus.cs-17] GetStatus for IP: 192.168.0.231 on port: 5016 9/10/2015 11:29:16 AM [0-3-1-SecondaryPortStatus.cs-47] <TRANSACTION> <FUNCTION_TYPE>SECONDARYPORT</FUNCTION_TYPE> <COMMAND>STATUS</COMMAND> <MAC_LABEL>P_061</MAC_LABEL> <MAC>az4FMuLbvrPz720bBeKWz3c+zBh6MsKVo4nJEW96B04=</MAC> <COUNTER>217</COUNTER> </TRANSACTION> 9/10/2015 11:29:16 AM [0-3-1-SecondaryPortStatus.cs-57] <RESPONSE> <RESPONSE_TEXT>Operation SUCCESSFUL</RESPONSE_TEXT> <RESULT>OK</RESULT> <RESULT_CODE>-1</RESULT_CODE> <TERMINATION_STATUS>SUCCESS</TERMINATION_STATUS> <COUNTER>217</COUNTER> <SECONDARY_DATA>10</SECONDARY_DATA> <SERIAL_NUMBER>285498613</SERIAL_NUMBER> </RESPONSE> 9/10/2015 11:29:16 AM [0-1-1-LandingPage.xaml.cs-49] POS opened However when running the nxlog.conf for this I am getting the following error  2015-09-15 08:00:43 ERROR couldn't parse expression at line 12, character 13 in C:\Program Files (x86)\nxlog\conf\nxlog.conf; invalid character: '\' I am unsure what i need to do in order to get this correct; does anyone have any insight or resources I should further explore. Is there a REGEX specific doc for NXLOG? 

I need to create new extension module but I cannot deduce some base code structure for such thing. Is there available some piece of code for new module?

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.

(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 ?

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
