Hi everyone I'm very new to this and have searched around but couldn't find anything obvious. I have a few Pc's with NXLog Community Edition sending data to a Loggly instance, event log data They are picking up Security and System and Application ogs out of the box it seems, but i'm wondering if i need to do anything to add other event log sources to have them sent to Loggly? Is it a matter of adding something to the Conf file? For example, I have Kaspersky AV on an endpoint and i want to pick up the specific Event Log where Kaspersky sits. Am i explaining it right? I basically want to add other event Log types into the process of log sending Mark

Hello, I am in the process of setting up NXLOG to capture syslog messages via TLS, but I have issues with the TLS connection, specifically: ERROR SSL certificate verification failed: unsupported certificate purpose (err: 26) Certificate for NXLOG was issued with the following: OID=1.3.6.1.5.5.7.3.2; Client authentication OID=1.3.6.1.5.5.7.3.1; Server authentication Is there any documentation on how to request certificates for NXLOG? I do not have NXLOG manager. Cheers

Hello, I am evaluating the om_ssl (GELF) module of nxlog EE agent for a large number of devices with TLS authentication of the devices enabled at Graylog. We already have the certificates in the Windows certificate manager on the devices which we would use for the nxlog agent as well. The certificates are rotated frequently, and thus nxlog.conf needs to be kept up to date (with the thumbprints) and due to the large number of devices we cannot create and update the configuration files by hand. What is the best practice to populate nxlog.conf with the required certificate thumbprints from the certificate store on each device and keep the configuration up to date? Thank you!

I have installed NX Log agent on a windows machine, but NX Log Manager is showing multiple hostnames for a single IP address, and because of this there are multiple Agents showing now, and none of them is working.

Hi, Is it possible to install two Nxlog agents on a single machine and governed by two respective NxLog managers? Regards.

NXLOG version: NXLog CE 3.0.2272 OS version: Windows 2019 server \ Windows 10 for client Issue: I inspect the communication between NXLog client and server via Wireshark. Client output module is om_ssl and server input module is im_ssl. I've been expecting to see the usage of TLS protocol, but all I see is TCP and RSH protocols, which are non secure protocols. How can this be explained? Client config: <Output out_ssl> Module om_ssl Host <host_ip> Port 514 OutputType Binary AllowUntrusted TRUE </Output> Server config: <Input in_ssl> Module im_ssl Host 0.0.0.0 Port 514 InputType Binary CAFile <CA path> CertFile <Certificate path> CertKeyFile <private key path> KeyPass <key password> AllowUntrusted TRUE RequireCert FALSE </Input> Wireshark is tracking 514 port on the server. Thanks!

Dear Friends How can I restrict sending records from windows? For example: From Eventviewer, I want to select only id "5145" regarding deleting files and folders... For I am receiving a very large amount of messages that I do not need. I ask for your help. Thank you.

Hello, I send data from MS SQL to SysLog, i use im_dbi+freetds and even if i have set SavePos it always starts from the beginning at startup.

I've configured NXlog to send printing events from our Windows 2012R2 print server to our Nagios LS instance. **Except **for the following issue, it works well. The issue is - when a filename contains a "%" sign, I receive a _grokparsefailure in Nagios. That led me to NXLog-CE and how it (and its modules) read/parsed the data from the Microsoft Windows PrintService Event Log. I enabled troubleshooting by means of debug AND outputting the $raw_event to a text file. Is there a way I can get this document name from the Windows Event Viewer into Nagios via NXlog-CE? This issue looks similar to this thread, which says the problem is with the provider: https://nxlog.co/question/2362/problem-windows-event DEBUG OUTPUT: {"EventTime":"2022-02-11 10:38:48","Hostname":"xxx.yyy.zzz","Keywords":4611686018427390016,"EventType":"INFO","SeverityValue":2,"Severity":"INFO","EventID":307,"SourceName":"Microsoft-Windows-PrintService","ProviderGuid":"{xxxxxxx}","Version":0,"Task":26,"OpcodeValue":11,"RecordNumber":2136143,"ProcessID":4764,"ThreadID":6728,"Channel":"Microsoft-Windows-PrintService/Operational","Domain":"XXXX","AccountName":"QQQQ","UserID":"SID-aaa-bbb-ccc","AccountType":"User",**"ERROR_EVT_UNRESOLVED":true**,"Category":"Printing a document","Opcode":"Spooler Operation Succeeded","EventReceivedTime":"2022-02-11 10:38:50","SourceModuleName":"eventlog","SourceModuleType":"im_msvistalog","message":null} $raw_event OUTPUT: 2022-02-11 10:38:48 xxx.yyy.zzz INFO 307 XXXX\QQQQ[The description for EventID 307 from source Microsoft-Windows-PrintService cannot be found: **The substitution string for insert index (%1) could not be found**. ] CONFIG: define ROOT C:\Program Files\nxlog define CERT %ROOT%\cert Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data LogFile %ROOT%\data\nxlog.log <Extension json> Module xm_json </Extension> <Extension syslog> Module xm_syslog </Extension> <Input internal> Module im_internal </Input> <Input eventlog> Module im_msvistalog <QueryXML> <QueryList> <Query Id="0"> <Select Path="System">*[System[Provider[@Name='Srv'] and (Level=1 or Level=2 or Level=3)]]</Select> <Select Path="Microsoft-Windows-PrintService/Admin">*[System[(Level=1 or Level=2 or Level=3)]]</Select> <Select Path="Microsoft-Windows-PrintService/Operational">*</Select> </Query> </QueryList> </QueryXML> </Input> <Output out> Module om_tcp Host qqq.yyy.zzz Port 1234 Exec $tmpmessage = $Message; delete($Message); rename_field("tmpmessage","message"); Exec $raw_event = to_json(); </Output> <Route 1> Path internal, file1, eventlog => out </Route>

Hi everyone After the update of the Nxlog community to the last version(3.0.2272) the consumption of CPU had a huge increase. The configuration basic work over the im_file module. <Input fake> Module im_file File "C:\fakedir\logs\fake_file*" SavePos TRUE Exec if $raw_event =~ /^#/ drop(); else { w3c->parse_csv(); $EventTime = parsedate($date + " " + $time); $Message = to_json(); } </Input> Is there someone that had the same issue with this version?

Hi team, i use the FIM module to monitor a test file and output it to 2 destination: local file and remote logstash with tcp. Now I could see the log in local file, but remote logstash fails to parse the log with json. After checking the log, i figure out that the log received by logstash is different: Local: {"EventTime":"2022-02-13T16:11:50.094508+08:00","EventType":"CHANGE","Object":"FILE","PrevFileName":"c:\users\test\desktop\test20220211.txt","PrevModificationTime":"2022-02-11T19:18:59.925713+08:00","FileName":"c:\users\test\desktop\test20220211.txt","ModificationTime":"2022-02-13T16:10:53.402144+08:00","PrevFileSize":6,"FileSize":10,"DigestName":"SHA1","Digest":"31ca8d2ae67b53db43d3581974d12a48c648eca5","PrevDigest":"1b1e2aa8fb50e43dd20429afdbbec1b81b153853","Severity":"WARNING","SeverityValue":3,"EventReceivedTime":"2022-02-13T16:11:50.094508+08:00","SourceModuleName":"fim","SourceModuleType":"im_fim"} Logstash: [2022-02-13T08:11:49,919][ERROR][logstash.codecs.json ][main][2869f035623bc8e694e78ee6b779cd6214f6eba705fdae0bea0b55fadc035072] JSON parse error, original data now in message field {:message=>"Unexpected character ('-' (code 45)): Expected space separating root-level values\n at [Source: (String)&quot;2022-02-13 16:11:50 HKLAP0240 WARNING EventType=&quot;CHANGE&quot; Object=&quot;FILE&quot; PrevFileName=&quot;c:\\users\\test\\desktop\\test20220211.txt&quot; PrevModificationTime=&quot;2022-02-11 19:18:59&quot; FileName=&quot;c:\\users\\test\\desktop\\test20220211.txt&quot; ModificationTime=&quot;2022-02-13 16:10:53&quot; PrevFileSize=&quot;6&quot; FileSize=&quot;10&quot; DigestName=&quot;SHA1&quot; Digest=&quot;31ca8d2ae67b53db43d3581974d12a48c648eca5&quot; PrevDigest=&quot;1b1e2aa8fb50e43dd20429afdbbec1b81b153853&quot; SeverityValue=&quot;3&quot;&quot;; line: 1, column: 6]", :exception=>LogStash::Json::ParserError, :data=>"2022-02-13 16:11:50 HKLAP0240 WARNING EventType=&quot;CHANGE&quot; Object=&quot;FILE&quot; PrevFileName=&quot;c:\\users\\test\\desktop\\test20220211.txt&quot; PrevModificationTime=&quot;2022-02-11 19:18:59&quot; FileName=&quot;c:\\users\\test\\desktop\\test20220211.txt&quot; ModificationTime=&quot;2022-02-13 16:10:53&quot; PrevFileSize=&quot;6&quot; FileSize=&quot;10&quot; DigestName=&quot;SHA1&quot; Digest=&quot;31ca8d2ae67b53db43d3581974d12a48c648eca5&quot; PrevDigest=&quot;1b1e2aa8fb50e43dd20429afdbbec1b81b153853&quot; SeverityValue=&quot;3&quot;"} { "tags" => [ [0] "jsonparsefailure" ], "message" => "2022-02-13 16:11:50 HKLAP0240 WARNING EventType=&quot;CHANGE&quot; Object=&quot;FILE&quot; PrevFileName=&quot;c:\\users\\test\\desktop\\test20220211.txt&quot; PrevModificationTime=&quot;2022-02-11 19:18:59&quot; FileName=&quot;c:\\users\\test\\desktop\\test20220211.txt&quot; ModificationTime=&quot;2022-02-13 16:10:53&quot; PrevFileSize=&quot;6&quot; FileSize=&quot;10&quot; DigestName=&quot;SHA1&quot; Digest=&quot;31ca8d2ae67b53db43d3581974d12a48c648eca5&quot; PrevDigest=&quot;1b1e2aa8fb50e43dd20429afdbbec1b81b153853&quot; SeverityValue=&quot;3&quot;", "@version" => "1", "host" => "53959da2d559", "@timestamp" => 2022-02-13T08:11:49.924Z, "path" => "/opt/nxlog/var/log/nxlog/logmessage.log", "type" => "json" } It seems the "2022-02-13 16:11:50 HKLAP0240 WARNING " is added only in the tcp stream and could not be identified as Json format by logstash. Is it normal to see the scenario and is there any workaround? Thank you.

Hi guys! I'm wondering where to download nxlog community edition version 2.11. The link I have doesn't work anymore — https://nxlog.co/system/files/products/files/348/nxlog-ce-2.11.2190.tar.gz I'm not sure whether it's ok or not for project I'm currently working on to switch to version 3 of nxlog. Could it be possible to keep old source code archives on nxlog's website? (I've also looked through gitlab, but unfortunately there is no version tags too...)

Hello All, I have an issue with sysmon logs. When they contain characters "è" like on word "système" nxlog convert it to "Syst�me". Could you please tell me how I can resolve this issue ? I've already tested the instructions bellow, but I always have an issue <Extension charconv> Module xm_charconv AutodetectCharsets iso8859-1, utf-8, utf-16, utf-32 </Extension> <Input input> Exec convert_fields("auto", "utf-8"); </Input> Best regards,

Converting events to Snare format and sending them out over TCP syslog <Output out> Module om_tcp Host 192.168.1.1 Port 514 Exec to_syslog_snare(); Can someone please tell me what's the purpose of the HOST IP, by default it's set to 192.168.1.1. What exactly should it be? Thanks

Hi All, I want to write windows events to a new file every 1 min. As of now, I have the following Output block in my conf which works. It is given below, <Output file> Module om_file File "C:\\Program Files (x86)\\nxlog\\data\\nxlog-output.json" <Schedule> Every 1 min Exec rotate_to(file_name() + strftime(now(), '_%Y-%m-%d_%H-%M-%S')); </Schedule> </Output> But in this case, I always write to the same file i.e "C:\Program Files (x86)\nxlog\data\nxlog-output.json" and after 1 min, the data is saved in other file with naming convention mentioned above. I want to create a new file every 1 min with above naming convention and then write to that file instead of writing to the same file. **How can I do this? Admins please guide. **

Hello, I have this problem on the servers of one of my clients: nxlog receives a termination signal many times a day, and it closes. Then it restarts, sometimes instantly, other times after a random amount of time. I can't identify the source of the signal, but this happens only on the servers of one of my clients. On the Windows eventviewer only show that nxlog service has stopped and then restarted. I tried updating from 2.9.1716 to 3.0.2272, but this behaviour didn't change. This is what I see in the nxlog.log everyday: 2022-02-07 00:25:12 WARNING stopping nxlog service 2022-02-07 00:25:12 WARNING nxlog-ce received a termination request signal, exiting... 2022-02-07 00:26:12 INFO nxlog-ce-3.0.2272 started 2022-02-07 01:59:14 WARNING stopping nxlog service 2022-02-07 01:59:14 WARNING nxlog-ce received a termination request signal, exiting... 2022-02-07 02:00:14 INFO nxlog-ce-3.0.2272 started 2022-02-07 03:49:15 WARNING stopping nxlog service 2022-02-07 03:49:15 WARNING nxlog-ce received a termination request signal, exiting... 2022-02-07 03:50:16 INFO nxlog-ce-3.0.2272 started 2022-02-07 05:42:17 WARNING stopping nxlog service 2022-02-07 05:42:17 WARNING nxlog-ce received a termination request signal, exiting... 2022-02-07 05:43:17 INFO nxlog-ce-3.0.2272 started 2022-02-07 07:34:18 WARNING stopping nxlog service 2022-02-07 07:34:18 WARNING nxlog-ce received a termination request signal, exiting... 2022-02-07 09:24:20 INFO nxlog-ce-3.0.2272 started The last time it stopped this morning, it stayed off around 2 hours. I think it's the Windows service control that restarts it, but sometimes it fails or get delayed somehow, but I can't prove it: there's nothing on the windows logs apart from the service start/stop notice. I searched the forums and see others have this problem, but cannot find a real solution or hint on where to search.

Hi, I’m looking for the steps to configure HTTPS for NxLog Manager using a CA signed cert. The doc provided is very limited. Please kindly advise. Thanks !
