Hello, After looking on the community forum i didn't really get the answer i was seeking. I'm sending windows log to a syslog and to a splunk, I got some issue about parsing the Message part as you can see : https://cdn.discordapp.com/attachments/700242491227635714/766300884971159562/unknown.png This is my conf : https://cdn.discordapp.com/attachments/700242491227635714/766301478897451048/unknown.png https://cdn.discordapp.com/attachments/700242491227635714/766301597541335060/unknown.png Maybe this is not the good way to do it, i have to send in syslog because i'm sending it after to an elasticsearch and the splunk. Thank you for your help :)

Hello In the end I have to come to you because I can't find the way to do it and I'm going a bit crazy. I have a record entry from a file. This file sends the data in a disorderly way and I have managed to assign it to variables. Now the only thing I want is to create an output in a file but with the order I need. EJ of log entry : user1 2020 barcelona 12 13:39 12 spaghetti And I want an exit like Place: <variable of place> , Date: <variable of date> , Age :<variable of age> To generate a line like this : Place : barcelona , Date : 2020 , Age : 12 .... This is my config. <Input LOG_IN> Module im_file File "C:\logs\u_ex*" SavePos TRUE <Exec> if $raw_event =~ /(.?)\s"(.?)"\s"(.?)"\s(.?)\s(.?)\s(.?)\s"(.?)"\s"(.?)"\s(.?)\s(.?)\s(.?)\s"(.?)"\s"(.?)"\s(.?)\s(.?)\s"(.?)"/; { $a = $1; $b = $2; $c = $3; $d = $4; $e = $5; $f = $6; $g = $7; $h = $8; $i = $9; $j = $10; $k = $11; $l = $12; $m = $13; $n = $14; $o = $15; $p = $16; } </Exec> </Input> <Output file> Module om_file File "C:\logs\output.log" </Output>

Hi. I'm new to both Graylog and NxLog. I am getting the following errors when trying to add inputs. 2020-10-14 11:48:27 WARNING stopping nxlog service 2020-10-14 11:48:27 WARNING nxlog-ce received a termination request signal, exiting... 2020-10-14 11:48:28 ERROR invalid keyword: Output at C:\Program Files (x86)\nxlog\conf\nxlog.conf:66 2020-10-14 11:48:28 ERROR module 'graylog' has configuration errors, not adding to route 'graylog_route' at C:\Program Files (x86)\nxlog\conf\nxlog.conf:70 2020-10-14 11:48:28 ERROR route graylog_route is not functional without output modules, ignored at C:\Program Files (x86)\nxlog\conf\nxlog.conf:70 2020-10-14 11:48:28 WARNING no routes defined! 2020-10-14 11:48:28 WARNING not starting unused module win 2020-10-14 11:48:28 WARNING not starting unused module graylog 2020-10-14 11:48:28 INFO nxlog-ce-2.10.2150 started I added the following lines to my config file <Extension _gelf> Module xm_gelf </Extension> <Input win> Module im_msvistalog Query <QueryList> <Query Id="0"> <Select Path="Application"></Select> <Select Path="System"></Select> <Select Path="Security">*</Select> </Query> </QueryList> </Input> <Output graylog> Module om_udp host 172.16.101.33 Port 12201 Output Type GELF </Output> <Route graylog_route> Path win => graylog </Route> Any help is appreciated.

In my design, there are collectors placed in security zones, receiving logs from a great number of Linux servers and forwarding the incoming to a Master Collector. This works perfectly fine :) My Collector's Input is defined like: <Extension _syslog> Module xm_syslog </Extension> <Input in1> Module im_tcp Host 0.0.0.0 Port 514 Exec parse_syslog(); </Input> but with one exception: In one of the zones I'm supposed to receive logs from the firewall - I can see in the nxlog.log the connection is accepted, but then it says connection accepted from [X.X.X:X]:port couldn't bind tcp socket to [X.X.X.X]:514; cannot assign requested address and I don't get any firewall logs. What is the proper fix for this?

I am trying to filter certain Windows Server events. I have the following code: <Exec> if $EventID == '4737' AND $TargetSid == 'S-1-5-21-3629192509-3943823860-1568066966-20147' AND $SubjectUserSid == 'S-1-5-21-3629192509-3943823860-1568066966-20118' { drop(); } if $SubjectUserName == 'NETVAULT$' AND $SubjectUserSid == 'S-1-5-20' AND ($ProcessName == 'C:\Program Files (x86)\Quest\NetVault Backup\pgsql\bin\postgres.exe' OR $NewProcessName == 'C:\Program Files (x86)\Quest\NetVault Backup\pgsql\bin\postgres.exe') { drop(); } if $SubjectUserName == 'HVAC$' AND $SubjectUserSid == 'S-1-5-18' AND ($ProcessName == 'C:\Program Files (x86)\Delta Controls\enteliWEB\PostgreSQL\bin\postgres.exe' OR $NewProcessName == 'C:\Program Files (x86)\Delta Controls\enteliWEB\PostgreSQL\bin\postgres.exe') { drop(); } </Exec> The first one says if the EventID, TargetSid, and SubjectUserSid are certain values, then drop the event. The second says that if the SubjectUserName and SubjectUserSid are certain values and either the ProcessName or NewProcessName are a certain value, then drop the event. The third basically is doing the same thing as the second one, except using different values. Do I have the syntax correct for this?

Hi, we are using NXlog to forward syslog messages, which works fine. But we have that strange <14> in the forwarded message: 3.127.197.211 **<14>**2020-10-13 09:58:54,443 message Konfig: <Input syslog514udp> Module im_udp Port 514 Host 0.0.0.0 </Input> <Output eventsentry> Module om_udp Host dstserver.domain.com Port 514 Exec $raw_event = $MessageSourceAddress + " " + $raw_event; </Output> Does anyone know why that happens? Thanks, Thomas

Our setup: we have Windows Server 2019 servers that are forwarding some "Security" events to a single Windows Server 2019 event collector. On that single Windows Server 2019 event collector, we have installed NXLog, which is forwarding to Graylog. Summary: servers --> event collector server (where NXLog is installed) --> Graylog server All selected events are getting to the event collector, but only some are getting to Graylog. So the problem is somewhere on or after the event collector server. Here is the complete NXLog config: 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 ShortMessageLength 500 </Extension> <Input in> Module im_msvistalog <QueryXML> <QueryList> <Query Id='0'> <Select Path='ForwardedEvents'>*</Select> </Query> </QueryList> </QueryXML> </Input> <Output out> Module om_tcp Host graylog.local Port 12201 OutputType GELF_TCP </Output> <Route 1> Path in => out </Route> Is anything obvious missing?

I traverse /var/log/myAPPLICATION* like shown below to harvest everything below in the folder structure, which has .log as extension. The challenge is now: What if there are occurences of logfiles that have e.g. .txt extension? Is it possible to use some conditional to that File line in the Input directive? Something like File "/var/log/myAPPLICATION/*.[log|txt]" <Input appLogs> Module im_file File "/var/log/myAPPLICATION/*.log" Recursive True SavePos True ReadFromLast True Exec to_syslog_ietf(); </Input>

We have installed nxlog community edition on Red Hat Enterprise Linux version 7.6. We included auth.conf but are not seeing any auth messages forwarded. I'm not understanding why Rsyslog is required since Rsyslog is capable for forwarding events by itself. Please share configs and experiences getting security and auth messages to forward.

Hi - pardon my ignorance I would like to use the om_python module to run a Python script s3_write.py which outputs to an S3 bucket on AWS I noticed the module wasn't included on the Community edition so I downloaded a trial of Enterprise and installed it, but im_python and om_python are not included with that either Nor can I find anywhere to download that module. How can I get hold of om_python please ? Kind regards

Installing nxlog to a 2008sp2 server. There is no C:\program files (x86) directory. Only Program Files. The service won't start because it is unable to find the program files (x86) directory. Are there other steps that need to be done to get this to work?

hello, first of all I would like to know is NXLOG-CE compatible with Windows server 2019. I have a lot of trouble implementing nxlog-ce on windows 2019 while on 2012 every thing is fine. the logs do not go up instantly and most of the time it does not work. someone has used nxlog-ce on windows 2019 ? sorry for my English :) Thank you for your answers with frensh : tout d'abord je souhaite savoir est ce que NXLOG-CE est compatible avec Windows serveur 2019. j'ai beaucoup de mal a implémenter nxlog-ce sur windows 2019 alors que sur de 2012 tout est bien fonctionnel et aucun soucis pour fare remonter les logs vers mon Syslog (kiwisyslog de solarwinds). les logs ne remontent pas instantanément et la majorité du temps cela ne fonctionne même pas. quelqu'un a t-il déjà utilisé nxlog-ce sur du windows 2019. merci pour vos réponses

Have created this simple agent to send agent logs to a central server. Is it possible to bulk this and only send once per hour ? What requirements to use the same as agentless ? When I add a second agent, how does the NXlog server separate the logs ?

Hi! I was wondering if anyone had any thoughts on this. I am using NXLog CE on Windows. I want to use om_file to export a log file to a network share folder. This share only allows AD domain users to read/write to the network share folder. I found that when I try to do this I get permission denied. This is obviously because I haven't assigned a domain account for NXLog to use, and I assume NXLog uses a local system account. Is there a way I can make NXLog use Domain credentials when doing this file transfer? Or is there another output module I should use? I am new to NXLog, apologies if this is a simple answer :)

Dear all, I was wondering if there was IPv6 support in the latest nxlog-community edition release? According to the Documentation (NXLog Community Edition Reference Manual) it seems IPv6 is supported. IPv6 Address An ip6addr type stores an IPv6 address in an internal format. But according to my nxlog.log errors I see the following: 2020-09-08 15:59:00 INFO nxlog-ce-2.10.2150 started 2020-09-08 15:59:00 ERROR apr_sockaddr_info failed for :::515;Address family for hostname not supported 2020-09-08 16:00:49 ERROR invalid keyword: ListenAddr at /etc/nxlog.d/listener.conf:26 Can you confirm that IPv6 should theoretically be supported in 2.10.2150 ? If so, what needs to be enabled in the config if used with im_tcp ? If it's not supported (because currently only supported in the Enterprise Edition), are there any plans to include this also in the Community edition soon? thanks and best regards, micsnare
