The objective is to configure the Nxlog to send logs to Sentinel LAW. The output module used is om_azuremonitor. The DCE URI directive depends on DNS resolution to resolve the url to ip. We added entry in the local /etc/hosts filleBut nslookup on the URI fails.Any inputs how the DNS can be resolved.There is no specific DNS server configured

Hi,I have the configuration below in which I would like to collect data from “Security" and from ”ForwardedEvents".I would like the data from the Security to be with specific values (e.g. $TaskValue, $Version) while ForwardedEvents ignore them. How can I configure it?

Hi! Can somebody help me with how DNS resolution works in Nxlog configuration?Thx !

Hey i try to send logs in TCP from nxlog instance to another to make kind of a proxy so i can set the parse of logs from one place and easier time to configure TLS rather than in my syslog server. But i receive a “end of file” error when the tcp connection is trying to be made between the 2 nxlog-ce instances. So i think i might using the nxlog-ce in a way its not designed to, am i right? Thank you.

Hello everyone,I need your help with my issue.I use the CE version and restarting the nxlog service, I receive errors loading the xm_resolver.dll & xm_admin.dll modules in the log file. After checking, I noticed that these DLLs are not present on my machine.2023-12-27 17:48:27 ERROR Failed to load module from C:\Program Files\nxlog\modules\extension\xm_resolver.dll, The specified module could not be found. ; 2023-12-27 17:48:27 ERROR Failed to load module from C:\Program Files\nxlog\modules\extension\xm_admin.dll, The specified module could not be found. ; Do you have any idea on how to solve this issue and how can I get these DLLs?Thanks in advance,

Hi Support,I would like to inquire whether NXLog supports tamper-proofing for syslog received and stored in the NXLog Relay Server.Thank you.Regards,Billy

Hello :) I have a friend that is asking why he cant find nxlog on his pc under installed applications, When I run the .msi file I can find it easily. Did his previous security officer install it a different way? (On Windows) Also how can I see what version of nxlog is currently running? (On Windows) Thanks

Hi, Have just installed NXLog Enterprise Trial - however I cannot start the service - getting error message : nxlog[1711122]: 2022-01-20 09:19:34 ERROR [CORE|main] This NXLog version has expired. Any idea how the trial license is applied? Any assistance would be greatly appreciated. Kind regards, Liam

I'm using NX log enterprise to collect Sysmon logs.I have a problem with EventID 12 , In the original (Windows view ) the event type is set to EventType: CreateKeyAs part of the NXlog output, in the Metadata the Event type is set to INFO and only in the msg field i can see the EventType: CreateKey  Please advice 

Good Afternoon Team.I have a nxlog service running on a windows server. It has input rule to collect syslog from several devices like this: <Input syslog514udp>Module im_udpPort 514Host 0.0.0.0<Exec> $raw_event =~ s/\r?\n/#012/g; parse_syslog_bsd();</Exec> </Input>  I am trying to forward the syslog of one specific device (10.10.10.10) to a public IP 190.20.30.40, but the filter is not working since nxlog is forwarding everything, configuration bellow: <Output OutNetomi>Exec if ($MessageSourceAddress == ‘10.10.10.10’) drop();Module  om_udpHost    190.20.30.40Port    514</Output> Do you know where the error is? Thank you.Diego.

Hi all,I am currently using Nxlog CE v3.2.2329 in a Virtual Machine Windows 10 21H2 for sending logs to a Rsyslog server using Syslog RFC5424 version.For this configuration, i use im_msvistalog for input and om_tcp with Exec to_syslog_ietf(); command to send them to the rsyslog server.<Input Source_Eventlogs> Module im_msvistalog </Input> <Output Dest_LogServer> Module om_tcp Host 192.168.1.1 Port 514 Exec to_syslog_ietf(); </Output> <Route send> Path Source_Eventlogs => Dest_LogServer </Route>In the rsyslog server i receipt logs using a template who send logs to the right folder and then the right file log$template DynamicFile,"/var/log/rsyslog/%HOSTNAME%/%syslogseverity-text%.log" *.info -?DynamicFileI met a first issue with security logs who where sent to a folder using the IP address. I assumed the issue was due to a failed resolving name and after adding the Nxlog client name to the /etc/hosts file and it solved the first issue.I met a second issue with Eventlogs who create many folder in the rsyslog folder because the logs are sent without hostname.For example i receive logs in a folder name VMICTimeProvider and when i look to the notice.log file i can see that there is no hostnamecat VMICTimeProvider/notice.log 2023-07-22T09:18:39.022270+00:00.

Hello, I am using nxlog-ce 3.2.2329 on a Windows 10 system to forward logs to a syslog-ng server over TCP using the to_syslog_ietf() procedure. This is working well for most logs, but I am occasionally seeing logs being generated with carriage returns and newlines in the syslog structured data element. Here is an example captured from tcpdump. Note that this is just the beginning of the message, enough to show you where the cr lf's are in the PrivilegeList element:<14>1 2023-10-18T16:23:21.669254-04:00 SteveAcer Microsoft-Windows-Security-Auditing 952 - [NXLOG@14506 Keywords="-9214364837600034816" EventType="AUDIT_SUCCESS" EventID="4672" ProviderGuid="{54849625-5478-4994-A5BA-3E3B0328C30D}" Version="0" Task="12548" OpcodeValue="0" RecordNumber="2053808" ActivityID="{FE9334EF-0152-0002-AD35-93FE5201DA01}" ThreadID="30200" Channel="Security" Category="Special Logon" Opcode="Info" SubjectUserSid="S-1-5-18" SubjectUserName="SYSTEM" SubjectDomainName="NT AUTHORITY" SubjectLogonId="0x3e7" PrivilegeList="SeAssignPrimaryTokenPrivilege SeTcbPrivilege SeSecurityPrivilege SeTakeOwnershipPrivilege SeDelegateSessionUserImpersonatePrivilege" EventReceivedTime="2023-10-18 16:23:23"The body of the message has cr lf's converted to spaces. In the documentation, I see reference to a ReplaceLineBreaks directive that defaults to converting the cr lfs to spaces, but that doesn't appear to apply to the syslog structured data. Is there a way I can remove these cr lfs from the PrivilegeList, or any element?
