Hi,We encounter below error during the installation where directory /opt/nxlog was not created and agent not running.

Hi,I am using this code snipping<Input EventLOG>Module im_msvistalogExec if ($TargetUserName == 'SYSTEM') OR ($EventType == 'VERBOSE') drop();</Input>This is working fine with my nx-Client at Windows 11. It push notification at my debian server with installed rsyslog server.But I want to have some specific ID´s from Windows Eventlog.( e.g. 5013, 10016, 4616, 6869)Can anybody point me to the right way? Thanks in Advance for every help. Heinz  

Hello,We are setting up log collection from Azure Log Analytics workspace but the connection is not possible without B2B proxy. I see that Proxy setup is possible only with om_azure module. We need to read and collect the logs from the Azure environment and not to send it there. What should we do to make it happen? Without proxy the connection is not possible and we can't use nxlog for our new service. Is there any other module which could set the proxy by default etc. ? Thank you,Martin W.

We currently have a central logging server for our Windows Servers collecting and forwarding with NXLog to AlienVault.  We have a working config file currently that I would like to modify to be able to send two of the Windows Event ID's that are being collected to our NDR (Vectra).  What is the best route to be able to configure multiple sources and/or outputs? Currently we have two working configs, one for Vectra and one for AlienVault, but I'd like to “combine” them in a way that allows us to be able to send relevant data to their needed sources.AlienVault uses a patterndb.xml file for what events it wants to collect, Vectra just needs two specific event ID's that it calls out in the log file with the below line. It then outputs to an IP.  This seems like it should be pretty straight forward but I'd like to have it sort of configured/figured out before I bring down my AlienVault feed.We are also currently using the Nxlog community edition if that matters.<Input eventlog>   Module im_msvistalog<QueryXML> <QueryList>  <Query Id="0" Path="ForwardedEvents">  <Select Path="ForwardedEvents">*[System[(EventID=4768 or EventID=4769)]]</Select> </Query></QueryList></QueryXML></Input>

Hi, I am trying to use an ssl connection between client and server in "server-side authentication only" mode. I placed the certificates in the respective /conf folder of nxlog server. these are the current configurations: >>> CLIENT <<< <Output to_syslog_server> Module om_ssl Host 10.1.1.1 Port 516 Exec $Message = to_leef(); to_syslog_ietf(); </Output> >>> SERVER <<< <Input in_syslog_ssl> Module im_ssl Host 0.0.0.0 Port 516 CAFile %CERTDIR%/rootCA.pem CertFile %CERTDIR%/central.crt CertKeyFile %CERTDIR%/central.key KeyPass password FlowControl TRUE AllowUntrusted TRUE <Exec> if $raw_event =~ /LEEF/ parse_leef(); else parse_syslog(); </Exec> </Input> but it makes me this Error: 2019-09-06 17:43:26 ERROR remote ssl socket was reset? (SSL_ERROR_SSL with errno=9); End of file found Do you have any ideas to solve this? Thank you Antonio

All,Hopefully an easy question.I am currently collecting Windows event logs on a dedicated forwarding server (using native WEF) in a dedicated event log (named “Forwarded Events”).  I have NxLog installed on this server and logs are being sent properly to my SIEM.Currently I am having difficulties filtering events where the SubjectUserName field ends with “$” symbol (logs are still reaching my SIEM). Below is a snippet of my configuration.  I am running NXLog Enterprise version 6.2.Please advise.<Extension json> Module xm_json </Extension> <Input windows_security_eventlog> Module im_msvistalog ReadFromLast True SavePos True <QueryXML> <QueryList> <Query Id="0"> <Select Path="ForwardedEvents">*</Select> </Query> </QueryList> </QueryXML> <Exec> ################################################### # Drop noisy machine object access (4662) events.# ################################################### if $EventID == 4662 AND ($SubjectUserName =~ /(.)$/) drop(); </Exec> </Input>

Hello all,  In the below code, “CID.*” is the regex that im using but in order to make the code generic I need to use a variable instead of regex, kindly let me know the fix for it or a way to go arround it . Main issue: I need to run “supressed” function for every different log separately such that one log of every type is suppressed.Thanks!!<Processor dup_drop>   Module pm_evcorr <Suppressed>     Condition $raw_event =~ /CID.*/     Interval 90     Exec $MSG = $raw_event; </Suppressed> </Processor>

I have a Powershell script that is retrieving events from Windows Event logs that are written by a certain application.  It then parses the exception info from the Event_Data portion into separate fields and combines them into JSON (the exception info is written in one big block of text, but each line has fields that we want to separate out into distinct fields so that the data is easier to filter in Kibana.  I have an input im_exec module in nxlog.conf that runs that script and a route to send that input to an om_tcp output for our logstash instance.  This works fine when you restart the service, however I'm having a problem getting this to pick up events after the initial restart.  I've tried adding a schedule both to the input module and adding an xm_exec module to restart the input module on a scheduled basis.  Anyone have any ideas on how to get this script to run repeatedly so that i can pick up and format new events?  I've looked through the schedule documentation and tried some of the suggestions on other discussions that look a bit similar, but none seem to have worked so far. This is what I have in the conf file currently:    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   LogLevel INFO      <Extension json>         Module xm_json   </Extension>   define LogFile %ROOT%\data\nxlog.log   <Input input_logs_powershell>   Module  im_exec   Restart true    Command "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe"   Arg     "-ExecutionPolicy"   Arg     "Bypass"   Arg     "-NoProfile"   # This specifies the path to the PowerShell script.   Arg     "-File"   Arg     "D:\Temp\events_parser.ps1"<Exec>       # Parse JSON       parse_json();   </Exec></Input> <Output logs_to_Kibana>      Module om_tcp      Host logstash_hostname      Port 6710   exec to_json();   </Output><Route input_logs_powershell>PATH input_logs_powershell =>logs_to_Kibana</Route> 

Hello there,I am experiencing the same reconnection issues on some VMs (Windows Server 2016 10.0.14393), but Nxlog connects successfully to our SIEM syslog sensor over port 601 from other VMs. When I run the netstat command on the affected servers, I see an “ESTABLISHED” connection between the server and the sensor (syslog server). The Windows firewall is disabled on all our servers.From the syslog server, there's a trace of successful packet exchange between the servers and the sensor. But I cannot see the Windows events in our SIEM platform.I have updated Nxlog CE to the latest version. Please help me resolve this issue.Thank you,Delvain

Hi teams, Hope you are doing well. I have some trouble implementing NXLOG on Windows 2016 server.

New Enterprise NxLog customer here…..hopefully any easy question.Today I am ingesting syslog messages from my PaloAlto Panorama instance into a dedicated syslog (Ununtu) server running syslog-ng.  I am using syslog-ng to parse the incoming logs into 3 distinct log files (traffic, threat, and system).   I am then using “logrotate” and “cron" to rotate, gzip, and retain the logs.I figure I have 2 options in terms of the log files themselves now that I am an nxlog customer.Option 1: Keep things as-is (since it is working now) and just use “im_file”.Option 2: Use nxlog to do the same things I am with syslog-ng.  Being new to nxlog, not sure how to best do this.If I want to go with Option #2, does anyone have a working configuration they would be willing to share on how they parsed the incoming syslog messages from Palo Alto into those 3 distinct files (or came up with a better alternative)? Thank you.

Hello NXlog world! I'm having some challenges to pull data from a SQL 2012 (running on W2K16) database using the im-odbc connector. This is my input: > <Input MSSQL_IN> > Module im_odbc > ConnectionString Driver={ODBC Driver 17 for SQL Server}; Server=XXXXXXXX; > Trusted_Connection=yes; DATABASE=XXXXX; > PollInterval 5 > IdType timestamp > SQL SELECT event_time AS 'id', f., a.name AS action_name > FROM fn_get_audit_file('C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\XXXXX\Log\Audit-File.sqlaudit', default, > default) AS f > INNER JOIN sys.dm_audit_actions AS a > ON f.action_id = a.action_id > WHERE event_time > ? > <Exec> > delete($id); > rename_field($event_time, $EventTime); > </Exec> > > </Input> The error I'm getting when starting NXlog is as follows: 2019-10-16 13:51:03 INFO nxlog-4.4.4431 started 2019-10-16 13:51:03 INFO im_odbc successfully connected to the database 2019-10-16 13:51:03 ERROR SQLExecDirect failed, 42000:2:300:[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]CONTROL SERVER permission was denied on object 'server', database 'master'.; 42000:3:297:[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]The user does not have permission to perform this action. (odbc error code: -1)` I have tried to enable of the permissions on the database (GRANT) but the CONTROL SERVER is throwing me off. I'm pretty sure is a stupid thing I haven't thought about, but since I am very new to NXlog, and obviously not a SQL admin, I am defeated! for now, so I'm hopeful someone, can help me with some guidance so I can troubleshoot further. TIA and happy hump day! JC

I am considering using NXLog Community Edition for a commercial application and wanted to confirm if this is permissible under the NXLog Public License. Are there any restrictions or limitations I should be aware of when using the Community Edition in a commercial setting? Additionally, could you please highlight the major differences between the Community and Enterprise editions that could impact a commercial deployment? Thank you for your assistance!

I uninstalled the community version and trying to install the enterprise version, I am getting this error - Service nxlog could not be stopped, verify that you have sufficient privileges to stop system services. I am a global admin. Please help

Whenever I try to run the .msi to install the Nxlog CE I get this error message Am doing something incorrectly or is the download file broken?

Hello all. I wanted to know if anyone has had any luck or if it is possible to add a second <Output Out> configuration to the current nxlog.conf? Currently want to test a new log collector (Taegis) along side our current collector (Masergy) so we have streaming logs concurrently to each collector. e.gOutput out1>   Module om_tcp   Host 192.168.1.100   Port 514</Output> # Define the output to send logs to the second destination IP<Output out2>   Module om_tcp   Host 192.168.1.101   Port 514</Output> Thank you. 

Looking to test some ingest into a data lake to test searches adn dashboards.

Good Morning All,We would need to take advantage of the new features within NXLOG 6.0 EE.  Are there any instructions on to perform the upgrade from 5.0 to 6.0?  OR is this a revamp oft he whole environment and re-deployment of the agents?  I currently have 900 agents deployed and it would not make sense to re-deploy.
