Good Afternoon.I currently run a NX log solution that was setup by the vendor of our cloud IDS. I do know that we have a collection of logs coming from workstations to a central server and that server uploads the logs to the IDS. That being said, I have set up a gray log server on an Ubuntu box and I want to send my Windows DNS logs to that server so that I have a way to search DNS queries made by workstations should on of them become compromised. (via malware, ransomware, etc) I realize that there is already a config fiile for nx log that sends the event viewer logs so I am assuming that I would have to use that same file to have nx send dns logs to a different location (if that is even possible).   So my questions are, Is it possible to do that? If so, is the collection service that has to be stopped in order to edit the config file?I would send these logs to the same online IDS service but we are already going over our quota every month and management doesn't see the need to upgrade our service. Therefore, I am left to figure out another way to stay on top of DNS threat hunting. Any input will be greatly appreciated.

Hi Folks,I have a tcp output that has 3 hosts in sequence to send to graylog (failover), but I would like to "randomly" switch the ouputs to better distribute the load on the nodes. In my config example, 'graylog_1' will always receive all events. Is there a bultin solution for processor/output to send randomly to the multiple nodes?Config example:<Output out_graylog>   Module om_tcp     FlowControl False      Host 192.168.0.10:514 # graylog_1      Host 192.168.0.11:514 # graylog_2      Host 192.168.0.12:514 # graylog_3 </Output>A viP/loadbalancer for graylog is not the solution I'm looking for, I want to understand the power of nxlog and its customization.

It would be nice if you eliminate scrolling with wrapping in this forum posts.

Hi the pronblem is that all works but I don´t receive any log.Graylog version 4.3 in debian 11.  Sidecar graylog 1.2 and NXLOG 3.0 if my memory doesn´t fail.What can i do?Thanks and happy new year.

Guys, does anyone know where I can get information on average resource consumption by the Nxlog CE agent?Thanks.James \0/

Hello,I'm trying to forward the VPN logs of a Zyxel ATP700 to my SIEM (InsightIDR), the forwarding works fine, but I can't format them as indicated in this documentationhttps://docs.rapid7.com/insightidr/rapid7-universal-vpn/Can someone help me?Thank you

Currently, I have GrayLog running as a docker image on an unraid server. Everything is working well. I also have a MS Windows lab environment that I want to forward logs into Graylog with the help of nxlog. I followed the instructions at: https://docs.nxlog.co/userguide/integrate/graylog.html and I don't have any errors, but I also don't have any data. Any ideas on how I can troubleshoot this to determine where my issue is?

Can anyone tell me for certain if this module is only included in the Enterprise version? If so, where does one buy the Enterprise Version and what is it's approximate cost? (USD)

Hello Team,I am new to nxlog and i have a requirement to collect windows logs from 2003 servers and the agent version that i am using is “nxlog-ce-2.11.2190”As per the documnet i have used im_mseventlog module, but still getting error and not able to pull the logs from 2003 servers. If some one please share me the config file for 2003 servers would be a great help below is the error that we are getting when starting the nxlog service.2022-12-21 09:37:50 WARNING nxlog-ce received a termination request signal, exiting...2022-12-21 09:37:51 ERROR invalid keyword: QueryXML at C:\Program Files\nxlog\conf\nxlog.conf:272022-12-21 09:37:51 ERROR module 'eventlog' has configuration errors, not adding to route '1' at C:\Program Files\nxlog\conf\nxlog.conf:592022-12-21 09:37:51 ERROR route 1 is not functional without input modules, ignored at C:\Program Files\nxlog\conf\nxlog.conf:592022-12-21 09:37:51 WARNING no routes defined!2022-12-21 09:37:51 WARNING not starting unused module eventlog2022-12-21 09:37:51 WARNING not starting unused module syslogout2022-12-21 09:37:51 INFO nxlog-ce-2.11.2190 started my config file.#NoFreeOnExit TRUE define ROOT     C:\Program Files\nxlogdefine CERTDIR  %ROOT%\certdefine CONFDIR  %ROOT%\confdefine LOGDIR   %ROOT%\datadefine LOGFILE  %LOGDIR%\nxlog.logLogFile %LOGFILE% Moduledir %ROOT%\modulesCacheDir  %ROOT%\dataPidfile   %ROOT%\data\nxlog.pidSpoolDir  %ROOT%\data <Extension _syslog>    Module      xm_syslog</Extension> ############INPUTS######## <Input eventlog> Module im_mseventlog <QueryXML><QueryList><Query Id="0"><Select Path="Security">*</Select></Query></QueryList></QueryXML></Input> #<Processor eventlog_transformer>#Module pm_transformer#</Processor> #<Processor buffer>#Module pm_buffer#MaxSize 102400#Type disk#</Processor> <Output syslogout>#Module om_udpModule om_tcpHost syslogipPort 514 Exec to_syslog_snare(); </Output> #<Route 1> #Path eventlog => eventlog_transformer => syslogout #</Route> <Route 1> Path eventlog => syslogout </Route>

I'm sending im_msvistalog messages to splunk via to_json().  I'm ending up with a field AccessList like:AccessList: %%4423which I assume is some kind of mapping of:Access Request Information: Accesses: ReadAttributesfrom the “Message” component.  Is that right?  If so, it's fairly obscure.  Is there some way to preserve “Accesses” as is?  What is “AccessList” trying to tell me?  Is there somewhere I can go to decode it?

Hello team,How to get NXLog Manager license?Thank you Klevin

HiIs it possible to install nxlog-ce-3.1.2319.msi on Windows 2008 R2?Regards.

TEST

Hi, Doing my first steps with NXlog.I have managed to collect all “Security” windows event log and also managed to update the “Version” parameter to my own parameter - Just for a test purposes Now I need to perform 3 tasks Collect all “Security” windows event log - DoneUpdate the “Version” parameter from int to string - Done Update the “Hostname” parameter of specific event ID (for example EventID":4656) to “test”  - Please advice Thank you <Input eventlog>   Module  im_msvistalog   <QueryXML>       <QueryList>           <Query Id='0'>    <Select Path='Security'>*</Select>           </Query>       </QueryList>   </QueryXML><Exec>       $Hostname = "test" ;      # This task should be only for eventID 4656       $Version = string($Version);       to_json();   </Exec></Input> 

I am trying to use the example in https://docs.nxlog.co/ce/current/index.html#om_file for file rotation on Windows (nxlog-ce-3.1.2319).I receive the following errorERROR Couldn't parse Exec block at xxx.conf:104; couldn't parse statement at line 107, character 29 in xxx.conf; module file not found ERROR module 'testfile' has configuration errorsusing this configuration.   The output works fine if I don't use the functions,  so I assume om_file must be loading (by default?).<Output testfile> Module om_file File "E:/nxlog_output/active/nxlog-out.txt" <Exec> # Format output to_json(); # Rotate file based on size, move to staging folder if (file-&gt;file_size() &gt; 10M) { $stagingFolder = 'E:/nxlog_output/staged/'; $newfile = $stagingFolder + 'data_' + strftime(now(), '%Y%m%d%H%M%S') + '.log'; file-&gt;rotate_to($newfile); } &lt;/Exec&gt; </Output> 

Apologies if I'm being dense, but I need some help with navigation of this site.The upper-right search box on this page, (https://nxlog.co/community-forum/) never submits.   Is there another search function I can use?Google search results all point to URLs like https://nxlog.co/question/4970/iis-logs-containing-quotes-are-not-processing,  which return a 404 when I click through.
