I am having problems with the nxlog service being stopped randomly with the log entry: "WARNING nxlog-ce received a termination request signal, exiting...” I have nxlog installed on Windows 2016 server sending powershell windows event logs to Rapid7 IDR SIEM collector I have looked in application, security and system windows event logs, but I can't see what is stopping it.

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. [v8.2112.0]"}here <ip> = server names and I have basic conf, Please help me these.

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there are German umlauts within the value fields that are converted wrongly.This means that the JSON is no longer valid and Logstash cannot parse it.In example, the “Domain” key contains the German word NT-AUTORITÄT (umlaut before the last T).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. But in Notepad++ the output is shown as this:And as you can see, there are valid lower case umlauts in the message field: “empfängt derzeit gültige”How can I fix this? :( Thank you very much!   Thorsten

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.

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.

Dear Community,I am using NXlog community edition and am experiencing the problem that using the following configuration, the log sent to rsyslog arrives with the characters #011 as tab and #015 as carriage return: <Extension _syslog>    Module      xm_syslog</Extension> <Extension _charconv>    Module xm_charconv    AutodetectCharsets iso8859-2, utf-8, utf-16, utf-32</Extension> <Extension _exec>    Module xm_exec</Extension> <Extension json>    Module xm_json</Extension> <Input internal>    Module im_internal</Input> <Input eventlog>    Module im_msvistalogQuery <QueryList>\    <Query Id="0">\    <Select Path="Application">*</Select>\    <Select Path="System">*</Select>\    <Select Path="Security">*</Select>\</Query>\</QueryList>    Exec if ($EventID == 5156) OR ($EventID == 5158) drop();    Exec $HOSTNAME=hostname();    Exec $Message = replace($Message, "#011", " ");    Exec $raw_event = replace($raw_event, "#011", " ");#    Exec $Message =~ s/(\t|\R)/ /g;#    Exec $Message =~ s/(\t|\R|\011|\015)/ /g;</Input> <Output out>    Module om_tcp    Host %OUTPUT_DESTINATION_ADDRESS%    Port %OUTPUT_DESTINATION_PORT%    Exec $Message = replace($Message, "#011", " ");    Exec $raw_event = replace($raw_event, "#011", " ");    Exec to_syslog_snare();    Exec $Message = replace($Message, "#011", " ");    Exec $raw_event = replace($raw_event, "#011", " ");</Output> <Route 1>    Path eventlog, internal => out</Route> Can you tell me how to solve the problem? It seems not to remove the tab and carriage return characters.Thank you very much.

Good day,I was wondering if the CE will be releasing a version for Ubuntu 24.04 since this is a LTS release.Thanks,Jesse

Nxlog stops sending data to a route if another route is actively rejecting connections.The other output stops sending data after a while (from a few minutes to a day), although TCP-connection is supported.We use 2 routes at the same time with 1 input.There is our nxlog config: “The in1 module is used by both routes. ”Planforms: Windows 2016/2019 and Windows 2022nxlog.conf<Route r1> Path in => out1 </Route> <Route r2> Path in => out2 </Route>Logs:2024-11-21 13:28:53 INFO nxlog-ce-3.2.2329 started 2024-11-21 13:28:53 INFO connecting to Graylogserver:12523 2024-11-21 13:28:53 INFO connecting to Graylogserver:12527 2024-11-21 13:28:54 INFO reconnecting in 1 seconds 2024-11-21 13:28:54 ERROR couldn't connect to tcp socket on Graylogserver:12523; No connection could be made because the target machine actively refused it. 2024-11-21 13:28:55 INFO connecting to Graylogserver:12523 2024-11-21 13:28:56 INFO reconnecting in 2 seconds 2024-11-21 13:28:56 ERROR couldn't connect to tcp socket on Graylogserver:12523; No connection could be made because the target machine actively refused it. 2024-11-21 13:28:58 INFO connecting to Graylogserver:12523
