Hello,we using Nomad which sends logs in GELF format. We need to forward it to Rsyslog and also to Graylog. For Syslog I want to set $SourceName, which needs to be exracted from the JSON / GELF.The config looks like this: ... <Input container> Module im_tcp ListenAddr 127.0.0.1:12202 InputType GELF_TCP </Input> ... <Output syslog-container-server> Module om_udp Host ${user.logserver} Port 514 Exec to_json(); Exec $message =~ s/-p[^\s]+/-pXXX/; Exec to_syslog_bsd(); </Output> ... <Route container-to-syslog> Path container => syslog-container-buffer => syslog-container-server </Route>And the log on the rsyslog:Apr 15 15:24:26 qh-a07-nomad-agent-03 {"version": "1.1","Hostname":"qh-a07-nomad-agent-03","ShortMessage":"[2024-04-15 13:24:26] app.DEBUG: Connected to redis...PONG [] []","EventTime":"2024-04-15T15:24:26.376000+02:00","SeverityValue":6,"command":"/home/app/entrypoint.sh start php-fpm","container_id":"f1...","container_name":"iframes-c77e666c-fd39-f6f6-4d57-b416a4a7e28a","created":"2024-04-12T08:58:36.870730597Z","image_id":"sha256:2a26fed9c075899cfe86d74f8f44c2729be0f392a96d10c938795fe84036506d","image_name":"repos/production/iframes/production:68c00192","tag":"production","MessageSourceAddress":"127.0.0.1","EventReceivedTime":"2024-04-15T15:24:26.376703+02:00","SourceModuleName":"container","SourceModuleType":"im_tcp"}How can I extract container_nameand use for $SourceName = 'my_application';  so that “my_application” is replaced with the content of "container_name ?cu denny

I noticed that many Azure heartbeat logs will send to SIEM, if i want to config the nxlog output file, how to filter it out and make it not send the logs to SIEM? Thanks.

This might seem as an odd thing, but I have a need where I want to combine syslog as well as json in the same message. Syslog should be combined (without the message field) with the complete $raw_event as json. I've successfully converted the entire thing to json with $json_message = to_json();However when I attempt the same thing with to_syslog_ietf(); an error is thrown. How would I achieve this behaviour with CE?Couldn't parse Exec block at C:\Path\nxlog.conf:58; couldn't parse statement at line 72, character 42 in C:\Path\nxlog.conf; function 'to_syslog_ietf()' does not exist or take different arguments.

Hello,My current architecture is a windows nxlog agent sending logs to a remote syslog server. The agent is translating Windows event logs to json encapsulated syslog before sending them.I've encountered an inconsistency with the hostname field of the sent log, most of the sent logs contain the hostname as expected, but some only contains the IP address which creates a mess on the sorting I made on the remote syslog server.I haven't tried anything yet as I don't really know where to look for. My take is that it is a windows event log issue that can't be fixed but i'd like your opinions.Thank you for your help.

Greetings! I have a vulnerability in jQuery to be addressed in the nxlog manager v5 (5.5.5398). This is related to XSS vulnerabilities from the version of jQuery installed (1.8.3, 1.9.2 ui) . Will upgrading Manager to 5.6.5633 resolve the issue and update jQuery to 3.5.0+ ? If not, please can you provide steps to update jQuery manually? Thanks! Shyam (on behalf of Shashidhar Ghiliyal)

I find instructions for installing the Enterprise edition. I'm trying to install the Community edition. I can't find the tar file, only the rpm file.I cannot resolve all the missing dependencies:libc.so.6, libcrypt.so.2, libcrypto.so.3, libssl.so.3, libsystemd.so.0 I cannot convince my management to pay for the Enterprise edition without first demonstrating the Community edition. Since the documentation for the Community edition is so poor, I will not advocate paying to only find that the documentation for the Enterprise edition is no better. How do I install the needed dependencies?

Hello all, I have a bit of a problem and was hoping someone can put in their two cents. I have recently set up NXLogs to start sending DHCP logs to a second server for one of our security applications. However, there is no record of the logs being received by it (or any traffic to suggest that the logs are leaving the DHCP server). We are successfully receiving logs for the first Security Server, just not the second (most recent addition). I have ran a Netstat -a command from the DHCP server and it shows there is an active connection going to the correct IP range and port. We have looked at the firewall and found that there are no packets being dropped by it either, and also no records that traffic is going from our DHCP server to our second Security Server. So all in all, I'm at a bit of a loss for how to troubleshoot this and was wondering if anyone had any ideas? PSB for a copy of our .conf file, just in case anyone spots a glaring error (I have redacted IP ranges, ports, etc…) Panic Soft#NoFreeOnExit TRUEdefine ROOT     C:\Program Files\nxlogdefine WINDHCP_OUTPUT_DESTINATION_ADDRESS x.x.x.xdefine WINDHCP_OUTPUT_DESTINATION_ADDRESS2 x.x.x.xdefine WINDHCP_OUTPUT_DESTINATION_PORT xxxxdefine WINDHCP_OUTPUT_DESTINATION_PORT2 xxxModuledir   %ROOT%\modulesCacheDir    %ROOT%\dataPidfile     %ROOT%\data\nxlog.pidSpoolDir    %ROOT%\dataLogFile     %ROOT%\data\nxlog.log<Extension _json>   Module  xm_json</Extension><Input dhcp_server_eventlog>  Module      im_msvistalog  <QueryXML>       <QueryList>           <Query Id="0" Path="System">               <Select Path="System">*[System[Provider[@Name='Microsoft-Windows-DHCP-Server']]]</Select>           </Query>           <Query Id="0">               <Select Path="DhcpAdminEvents">*</Select>               <Select Path="Microsoft-Windows-Dhcp-Server/FilterNotifications">*</Select>               <Select Path="Microsoft-Windows-Dhcp-Server/Operational">*</Select>           </Query>      </QueryList>   </QueryXML>   Exec        $EventTime = integer($EventTime) / 1000;   Exec        $EventReceivedTime = integer($EventReceivedTime) /     1000;   Exec        to_json();</Input><Input audit_logs_csv>   Module      im_file   File        "c:\DHCP\-*.log"   SavePos     TRUE   InputType   LineBased   Exec        $Message = $raw_event;</Input><Output SecurityServer1>   Module      om_udp   Host        %WINDHCP_OUTPUT_DESTINATION_ADDRESS%   Port        %WINDHCP_OUTPUT_DESTINATION_PORT%</Output><Output SecurityServer2>   Module      om_udp   Host        %WINDHCP_OUTPUT_DESTINATION_ADDRESS2%   Port        %WINDHCP_OUTPUT_DESTINATION_PORT2%</Output><Route 1r>   Path     dhcp_server_eventlog,audit_logs_csv => SecurityServer1</Route><Route 2>   Path     dhcp_server_eventlog,audit_logs_csv => SecurityServer2</Route> Thanks in advance for the help. 

Hi So im a brand new user to NXLog,  and NXlog are refusing to offer me any support unless i pay for it, which i feel is a little unfair given i have literraly just purchased 8 Enterprise Editon licenses . However i have got a config file which im working with. So far i have two problems 1 - The resulting log file is empty2 - I am receiving the following errors2024-03-05 14:31:28 ERROR [im_maculs|uls] Could not get proc_info, skipping log @ 486802024-03-05 14:31:28 WARNING [im_maculs|uls] Avoided padding for log ending @ 0xBE39  I am not sure on the best course of action here, or wether i need to upload the actual config file, if anybody can offer any help or guidnace at all it would be greatly appreciated. More than happy to prove more info if it helps Thanks

Sorry if this has been asked before, but I couldn't find anything related.I'm after NXLOG version CE 2.9.1716 for Windows however only Ubuntu & Debian is available from the download section. Does anybody know how I can obtain the Windows file?
