I am using nxlog to get my Windows logs from a Domain Controller into a SIEM. I am using the im_msvistalog module. ProblemI am receiving logs with large amount of delay. The EventReceivedTime is much later than the EventTime. Please have a look at one of the sample logs output from nxlog. <14>Jun 24 10:56:26 EXHost1.Example.net Microsoft-Windows-Security-Auditing[0x28c0]: { "EventTime":"2025-06-24T10:56:26.039509+02:00", "Hostname":"EXHost1.Example.net","Keywords":"9232379236109516800","EventType":"AUDIT_SUCCESS","SeverityValue":2,"Severity":"INFO","EventID":4674,"SourceName":"Microsoft-Windows-Security-Auditing","ProviderGuid":"{91548763-9812-1113-B4AC-12BAC98DDE11}","Version":0,"TaskValue":13056,"OpcodeValue":0,"RecordNumber":355721231415,"ExecutionProcessID":4,"ExecutionThreadID":13033,"Channel":"Security","Message":"An operation was attempted on a privileged object.","Category":"Sensitive Privilege Use","Opcode":"Info","SubjectUserSid":"S-1-5-21-3604662650-2432062322-1707920734-40372","SubjectUserName":"Test_Subject","SubjectDomainName":"EXAMPLE","SubjectLogonId":"0x12ab121bc","ObjectServer":"Security","ObjectType":"-","ObjectName":"-","HandleId":"0x1168","AccessMask":"1048577","PrivilegeList":"SeBackupPrivilege","ProcessId":"0x28c0","ProcessName":"C:\\EXAMPLE\\HELLO\\HELLOBIN\\yxnw3018\\dispatch\\knex3alo.exe", "EventReceivedTime":"2025-06-24T13:04:13.896816+02:00", "SourceModuleName":"i_win","SourceModuleType":"im_msvistalog"}The delays are not consistent. The delays can be ranging from about 10 minutes to sometimes 2 or 3 hours. I have tried to find a pattern but failed to do so. The resources in the Windows device is sufficient and there has been no outstanding logs in nxlog/nxlog.log file. ConfigHere is the snippet of my config that I am using. Any help would be highly appreciated. ... <Extension _syslog> Module xm_syslog </Extension> <Extension _json> Module xm_json </Extension> <Input in> Module im_msvistalog </Input> <Output out> Module om_tcp Host 10.xx.xx.xx Port 514 Exec to_json();$Message=$raw_event;to_syslog_bsd(); </Output> <Route 1> Path in=>out </Route>

Hi there!Need help in managing windows logs… I need to receive logs that are only fall into warning and critical category. I understand that I need to use <Query> to filter logs, BUT I don't quite understand how to throw away info logs… It must be if $some_value_from_log == ‘INFO’ drop();Or maybe<QueryXML>       <QueryList>           <Query Id='1'>               <Select Path='System'>'WARNING'</Select>           </Query>       </QueryList>   </QueryXML>As for now my <Input> collect everything that fall into system logs category via select path… Any ideas? 

Hi, as per title, if I use the ReadOrder directive in an input with im_file module, I receive the error: ERROR invalid keyword: ReadOrder Do you have any suggestion on why?Input module example: <Input files> Module im_file ActiveFiles 36 ReadOrder MtimeNewestFirst Recursive True SavePos True File 'C:\inetpub\logs\LogFiles\\*.log' </Input> Thanks 

Hi,We are using NXLog-CE version 3.2.2329 and we prepare to deploy NX log agent in Windows server 2025.Is Nxlog CE version 3.2.2329 supporting log collection in Windows server 2025?If this version is not supported, what is the minimum version of NXLog CE to support Windows server 2025?Thanks.

Hi All,I installed nxlog on my windows server 2003 and send logs to the rsyslog server but it gives error logs like belowApr 29 16:23:06 log-collector rsyslogd[658]: imtcp imtcp: Framing Error in received TCP message from peer: (hostname) <ip>, (ip) <ip>: delimiter is not SP but has ASCII value 68.

I am trying to collect Windows 11 events on a localized system (in my case: German) and send them to Logstash.Sometimes there are German umlauts within the value fields that are converted wrongly.This means that the JSON is no longer valid and Logstash cannot parse it.In example, the “Domain” key contains the German word NT-AUTORITÄT (umlaut before the last T). This is translated to “AUTORIT0xC4T”, where 0xc4 seems to be a part of U+00C4. This is the unicode expression of Ä. The correct  UTF-8 character is 0xC3C4. Interestingly, lower case umlauts are translated correctly. At least in the “message” field.Because 0xC4 alone is not a valid UTF-8 character, this cannot work. The parser in Logstash is then missing a byte and fails.I played around with “AutodetectCharsets” of xm_charconv in the nxlog.conf file: nothing changedThen I set "convert_fields("auto", "utf-8");" within the <input> block: did not change anything, too.An then I set "convert_fields("utf-8", "utf-8");" within the <input> block. That fixed the wrong Ä in AUTORITÄT, but broke all small umlauts.This is my nxLog configuration:<Extension json_encoder> Module xm_json </Extension> <Input eventlog> Module im_msvistalog Exec $Message = replace($Message, "\r\n", " "); <QueryXML> <QueryList> <Query Id="0" Path="Application"> <Select Path="Application">*</Select> </Query> <Query Id="1" Path="System"> <Select Path="System">*</Select> </Query> <Query Id="2" Path="Security"> <Select Path="Security">*</Select> </Query> <Query Id="3" Path="Setup"> <Select Path="Setup">*</Select> </Query> </QueryList> </QueryXML> </Input> <Output out> Module om_tcp Host 10.10.2.10 Port 5000 Exec to_json(); </Output> <Output localfile> Module om_file File 'C:\nxlog.txt' Exec to_json(); </Output> <Route route1> Path eventlog => localfile </Route> And this is an example of a faulty line in c:\nxlog.txt{"EventTime":"2025-05-05 18:27:39","Hostname":"Frodo","Keywords":-9223372036854775808,"EventType":"INFO","SeverityValue":2,"Severity":"INFO","EventID":37,"SourceName":"Microsoft-Windows-Time-Service","ProviderGuid":"{06EDCFEB-0FD0-4E53-ACCA-A6F8BBF81BCB}","Version":0,"Task":0,"OpcodeValue":0,"RecordNumber":163093,"ProcessID":17416,"ThreadID":9680,"Channel":"System","Domain":"NT-AUTORITĔ","AccountName":"Lokaler Dienst","UserID":"S-1-5-19","AccountType":"Well Known Group","Message":"Der Zeitanbieter \"NtpClient\" empfängt derzeit gültige Zeitdaten von pool.ntp.org,0x9 (ntp.m|0x9|0.0.0.0:123->194.164.164.175:123).","Opcode":"Info","TimeSource":"pool.ntp.org,0x9 (ntp.m|0x9|0.0.0.0:123->194.164.164.175:123)","EventReceivedTime":"2025-05-05 18:27:41","SourceModuleName":"eventlog","SourceModuleType":"im_msvistalog"}It is not such easy to post encoding problems.

I'm collecting log data using im_file that includes “domain\username” in a field. I run it through xm_csv to parse the csv formatted data into fields, then I extract that data with regex into a domain field and a username field, which works for all but those usernames that start with escape characters, n r t and b. I had been tweaking the regex at first thinking it was failing for some reason, but it really seems like the field is double quoted and is allowing escape characters to exist, even though I have it set to use a single quote when I parse the csv data.Windows Server 2019 Standard, NXLog CE version 3.2.2329.Input/Output exampleInput 2025/04/14,10:21:18,Disconnect,01DB045CCE64165800505699187E001,CD-PL-22-0030,domain\raymondc,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,50,0,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,1,, Output {"version":"v1","authentication_target":"vpn01","time":"2025-04-14 10:21:18","DeviceName":"CD-PL-22-0030","account":"domain\raymondc","event_type":"VPN_SESSION_TERMINATION"} ConfigPanic Soft #NoFreeOnExit TRUE define ROOT C:\Program Files\nxlog define CERTDIR %ROOT%\cert define CONFDIR %ROOT%\conf\nxlog.d define LOGDIR %ROOT%\data include %CONFDIR%\*.conf define LOGFILE %LOGDIR%\nxlog.log LogFile %LOGFILE% Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data <Extension _json> Module xm_json </Extension> <Extension _charconv> Module xm_charconv AutodetectCharsets iso8859-2, utf-8, utf-16, utf-32 </Extension> <Extension _exec> Module xm_exec </Extension> <Extension _fileop> Module xm_fileop # Check the size of our log file hourly, rotate if larger than 5MB &lt;Schedule&gt;

Hi,I’m leveraging the to_json() function to convert Windows Events to JSON before sending them. This generally works well, and most of the log is converted to JSON correctly. However, there’s a portion of the log where NXLog doesn’t format the data into proper JSON, instead inserting control characters like \r\n. This breaks the JSON formatting and results in an undesirable output.Here’s an example of a Windows Event that’s been converted to JSON. As you can see, the Message field includes control characters and retains the original structure of the event rather than being properly formatted as JSON:{"Channel":"Security","Message": "System audit policy was changed.\r\n\r\nSubject:\r\n\tSecurity ID:\t\tS-1-5-18\r\n\tAccount Name:\t\tclient01$\r\n\tAccount Domain:\t\tmydomain\r\n\tLogon ID:\t\t0x3E7\r\n\r\nAudit Policy Change:\r\n\tCategory:\t\tAccount Logon\r\n\tSubcategory:\t\tKerberos Service Ticket Operations\r\n\tSubcategory GUID:\t{foo}\r\n\tChanges:\t\tSuccess removed, Failure removed","Category":"Audit Policy Change"}Here’s an example of the output I’d like to achieve:{"Channel":"Security","Message":"System audit policy was changed.", "Subject":{"Security ID": "S-1-5-18","Account Name":"client01$","Account Domain":"mydomain","Logon ID":"0x3E7"},"Audit Policy Change":{"Category":"Account Logon","Subcategory":"Kerberos Service Ticket Operations","Subcategory GUID":"{foo}","Changes":"Success removed, Failure removed"},"Category":"Audit Policy Change"}Does anyone know if and how I can achieve this?NXLog CE is running on Windows Server 2022. Package version is 3.2.2329.

We're showing that NXLog CE has a DLL, libssl-1_1-x64.dll, that is using OpenSSL version 1.1.1q, which is vulnerable to CVE-2022-2097. Is there any plan to move to a newer version, or are there decent instructions for compiling the source code for Windows?

Hello. I am using nxlog community edition 3.2.2329_ubuntu20_amd64.deb on ubuntu 20.04.6. I am trying to rotate and purge logs on a daily basis. This is a dev environment that shuts down from 6pm to 7am daily. I tried using a Schedule block with a directive of When to @startup but that throws an error when starting nxlog.

I've been using NXLog to monitor a simple log file from an application and send it to Graylog using GELF. Very simple, very efficient, and it works just like I want it to. Now I want to monitor a 2nd log file from another application and send that to a separate input in Graylog (also using GELF). I thought it would be quick and simple to add the 2nd log file as another om_file imput and add a 2nd output to route the log file to. But for some reason, I just can't get the 2nd input/output to work. Here is my nxlog.conf file: ######################################## User nxlog Group nxlog LogFile /var/log/nxlog/nxlog.log LogLevel INFO ######################################## # Modules # ######################################## <Extension _gelf> Module xm_gelf </Extension> <Input APP1> Module im_file File "/var/log/logfile1.txt" </Input> <Input APP2> Module im_file File "/var/log/logfile2.txt" </Input> <Output Graylog1> Module om_udp Host 192.168.0.100 Port 12201 OutputType GELF </Output> <Output Graylog2> Module om_udp Host 192.168.0.100 Port 12203 OutputType GELF </Output> ######################################## # Routes # ######################################## <Route graylog_1> Path APP1=> Graylog1 </Route> <Route graylog_2> Path APP2 => Graylog2 </Route> What I've found is that if I also route the logfile2.txt to Graylog1, it works just fine. So both log files can be sent to Graylog1. But when I add that 2nd output, Graylog2, and route logfile2.txt to it, I never get any of those messages in Graylog. I know this isn't a Graylog forum, but am I missing something in my nxlog.conf or should I be looking more at the Graylog server?

Hi I am pretty new to nxlog, so I lack some knowledge. We have been using NXLog to send logs using sysmon to our IBM Qradar. On a few machines, we've seen some logs that arrived today, but are from 1-2 weeks ago. How exactly does NXLog keeps logs that have not been sent. Are there any steps we can use to investigate why these logs were sent with such a long delay? In most cases it all works without a problem, but on very rare occasions we receive a few really old events. Thank you

Hi All,We are using NXlog CE to forward from windows server to SIEM. But we are facing issue in delay of ingestion of events.  Error of NXlog file details is given. Please assist.

Is the binary src/utils/csed built or otherwise incorporated into the build?It doesn't look like it when I built it from source because the binary wasn't built by default, but I wanted to confirm.There is a buffer overflow in csed.c, and I need to make sure it doesn't find its way into the build.Thanks.

This defaults to 'INFO' if unset. if $raw_event =~ /\sSEVERE\s/ $Severity = 'CRITICAL'; else if $raw_event =~ /\sERROR\s/ $Severity = 'ERROR'; else if $raw_event =~ /\sWARN\s/ $Severity = 'WARNING'; else $Severity = 'INFO'; # The facility can be also set, otherwise the default value is 'USER'. $SyslogFacility = 'AUDIT'; &lt;/Exec&gt; </Input>We use the Last CE Version.: nxlog-ce-3.2.2329Thanks, regards Wolfgang
