Hi, I am Configuring om_ssl module for <Output tcpssl> for CE and successful in sending logs to logstash over SSL, however if I remove CertKeyFile I get an error "ERROR SSL error, SSL_ERROR_SSL: retval 0, sslv3 alert bad certificate". My question is why is private key desired here? Thanks, Sidd

Hello, When I install nxlog with an Administrator account and then try to uninstall with another account (even with admin privileges) I'm having issues, and I'm not able to do it. Any idea how to solve this issue?

Hi, I'm new to NXLog. Still learning how to deploy NXLog Manager and the agents. I'll like to know where can I download sample Verbatim templates for different environments like Linux, Windows Server, Windows 10 and so on. And also the configuration template to SIEM like LogRhythm and Splunk. TIA !

Hi, We are using nxlog ce-2.11.2190.msi to forward windows server event logs to our SIEM. And now we are seeing an issue that the $message of events with ID 4624/4625/4xxx are missing, while those of event with ID 7xxx are shown completely. This issue will be temporarily fixed if we restarted the nxlog service, but the same problem comes back after nxlog service running for a while. This is what we see on SIEM. And the complete events should be like: [Our server’s system language is Traditional Chinese, so the $message is displayed as bytes] Apr 12 18:19:36 win2k12.ahsuhome.local Microsoft-Windows-Security-Auditing[500]: Microsoft-Windows-Security-Auditing: 4634: \0xe5\0xb8\0xb3\0xe6\0x88\0xb6\0xe5\0xb7\0xb2\0xe7\0x99\0xbb\0xe5\0x87\0xba\0xe3\0x80\0x82 \0xe4\0xb8\0xbb\0xe6\0x97\0xa8: \0x09\0xe5\0xae\0x89\0xe5\0x85\0xa8\0xe6\0x80\0xa7\0xe8\0xad\0x98\0xe5\0x88\0xa5\0xe7\0xa2\0xbc:\0x09\0x09S-1-5-18 \0x09\0xe5\0xb8\0xb3\0xe6\0x88\0xb6\0xe5\0x90\0x8d\0xe7\0xa8\0xb1:\0x09\0x09WIN2K12$ \0x09\0xe5\0xb8\0xb3\0xe6\0x88\0xb6\0xe7\0xb6\0xb2\0xe5\0x9f\0x9f:\0x09\0x09AHSUHOME \0x09\0xe7\0x99\0xbb\0xe5\0x85\0xa5\0xe8\0xad\0x98\0xe5\0x88\0xa5\0xe7\0xa2\0xbc:\0x09\0x090x367342 \0xe7\0x99\0xbb\0xe5\0x85\0xa5\0xe9\0xa1\0x9e\0xe5\0x9e\0x8b:\0x09\0x09\0x093 \0xe7\0x95\0xb6\0xe7\0x99\0xbb\0xe5\0x85\0xa5\0xe5\0xb7\0xa5\0xe4\0xbd\0x9c\0xe9\0x9a\0x8e\0xe6\0xae\0xb5\0xe6\0x90\0x8d\0xe6\0xaf\0x80\0xe6\0x99\0x82\0xef\0xbc\0x8c\0xe5\0xb0\0xb1\0xe6\0x9c\0x83\0xe7\0x94\0xa2\0xe7\0x94\0x9f\0xe9\0x80\0x99\0xe5\0x80\0x8b\0xe4\0xba\0x8b\0xe4\0xbb\0xb6\0xe3\0x80\0x82\0xe9\0x80\0x99\0xe5\0x80\0x8b\0xe4\0xba\0x8b\0xe4\0xbb\0xb6\0xe5\0x8f\0xaf\0xe8\0x83\0xbd\0xe8\0x88\0x87\0xe4\0xbd\0xbf\0xe7\0x94\0xa8\0xe7\0x99\0xbb\0xe5\0x85\0xa5\0xe8\0xad\0x98\0xe5\0x88\0xa5\0xe7\0xa2\0xbc\0xe6\0x95\0xb8\0xe5\0x80\0xbc\0xe7\0x9a\0x84\0xe7\0x99\0xbb\0xe5\0x85\0xa5\0xe4\0xba\0x8b\0xe4\0xbb\0xb6\0xe6\0xad\0xa3\0xe9\0x9d\0xa2\0xe7\0x9b\0xb8\0xe9\0x97\0x9c\0xe3\0x80\0x82\0xe7\0x99\0xbb\0xe5\0x85\0xa5\0xe8\0xad\0x98\0xe5\0x88\0xa5\0xe7\0xa2\0xbc\0xe5\0x83\0x85\0xe6\0x9c\0x89\0xe5\0x9c\0xa8\0xe9\0x87\0x8d\0xe6\0x96\0xb0\0xe5\0x95\0x9f\0xe5\0x8b\0x95\0xe7\0x9b\0xb8\0xe5\0x90\0x8c\0xe9\0x9b\0xbb\0xe8\0x85\0xa6\0xe4\0xb9\0x8b\0xe9\0x96\0x93\0xe6\0x89\0x8d\0xe6\0x9c\0x83\0xe6\0x98\0xaf\0xe5\0x94\0xaf\0xe4\0xb8\0x80\0xe7\0x9a\0x84\0xe3\0x80\0x82 Our config is as below: define SIEM_IP 10.0.0.253 define ROOT C:\Program Files (x86)\nxlog define CERTDIR %ROOT%\cert define CONFDIR %ROOT%\conf define LOGDIR %ROOT%\data define LOGFILE %LOGDIR%\nxlog.log LogFile %LOGFILE% Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data <Extension syslog> Module xm_syslog </Extension> <Input in_eventlog> Module im_msvistalog ReadFromLast TRUE SavePos TRUE Query <QueryList> \ <Query Id="0"> \ <Select Path="Security">*[System[(EventID=1100 or EventID=1102)]]</Select> \ <Select Path="Security">*[System[(EventID=4768 or EventID=4769 or EventID=4771)]]</Select> \ <Select Path="Security">*[System[(EventID=4616 or EventID=4657)]]</Select> \ <Select Path="Security">*[System[(EventID=4624 or EventID=4625 or EventID=4634 or EventID=4647 or EventID=4648)]]</Select> \ <Select Path="Security">*[System[(EventID=5140 or EventID=5142 or EventID=5143 or EventID=5144 or EventID=5145 or EventID=5168)]]</Select> \ <Select Path="Security">*[System[(EventID=4656 or EventID=4658 or EventID=4660 or EventID=4663 or EventID=4664 or EventID=4985 or EventID=5051 or EventID=4670)]]</Select> \ <Select Path="Security">*[System[(EventID=4719 or EventID=4739)]]</Select> \ <Select Path="Security">*[System[(EventID=4720 or EventID=4722 or EventID=4723 or EventID=4724 or EventID=4725 or EventID=4726 or EventID=4738 or EventID=4740 or EventID=4767)]]</Select> \ <Select Path="Security">*[System[(EventID=4727 or EventID=4728 or EventID=4729 or EventID=4730 or EventID=4731 or EventID=4732 or EventID=4733 or EventID=4734 or EventID=4735 or EventID=4737 or EventID=4764)]]</Select> \ <Select Path="Security">*[System[(EventID=4741 or EventID=4742 or EventID=4743)]]</Select> \ <Select Path="Security">*[System[(EventID=4744 or EventID=4745 or EventID=4748)]]</Select> \ <Select Path="Security">*[System[(EventID=4749 or EventID=4750 or EventID=4753)]]</Select> \ <Select Path="Security">*[System[(EventID=4754 or EventID=4755 or EventID=4756 or EventID=4758 or EventID=4759 or EventID=4760 or EventID=4763)]]</Select> \ <Select Path="Security">*[System[(EventID=4778)]]</Select> \ <Select Path="Security">*[System[(EventID=4783)]]</Select> \ <Select Path="Security">*[System[(EventID=4800 or EventID=4801)]]</Select> \ <Select Path="System">*[System[(EventID=7036)]]</Select> \ </Query> \ </QueryList> </Input> <Output out_eventlog> Module om_udp Host %SIEM_IP% Port 514 Exec $SyslogFacilityValue = 17; Exec $Message = string($SourceName) + ": " + string($EventID) + ": " + $Message; Exec if ($EventType == 'ERROR' or $EventType == 'AUDIT_FAILURE') { $SyslogSeverityValue = 3; } \ else if ($EventType == 'WARNING') { $SyslogSeverityValue = 4; } \ else if ($EventType == 'INFO' or $EventType == 'AUDIT_SUCCESS') { $SyslogSeverityValue = 5; } Exec to_syslog_bsd(); </Output> <Route eventlog> Path in_eventlog => out_eventlog </Route> Any ideas about how can this happen will be appreciated.

Is there a way to control the serialisation nxlog does on the logs sent to kafka via om_kafka? Firstly i do not know how they serialise the messages sent to kafka as a result when I read these messages from kafka, i end up facing de-serialisation errors.

Hello, i havent found any official statement about supporting windows server 2022 by nxlog. Our customer is asking us about that. Is nxlog 5.0 supporting log collection for Windows server 2022?

Hi I have been trying to get this to work for 2 days but its not happening! i have a log that sometimes has java call stack errors (multiline) i ship these to graylog using nxlog. As you have guesed i have one log per line. So serched and found the xm_multiline module . Great but i cant get it to work as expected.

This works but I'm trying to filter out a service account username that is for cron tasks and is making the logs super noisy on my syslog server: Collecting event log <Input in> Module im_msvistalog <QueryXML> <QueryList> <Query Id="0"> <Select Path="Security"></Select> <Select Path="SentinelOne/Operational"></Select> <Select Path="Application">*</Select> </Query> </QueryList> </QueryXML> Exec $Message =~ s/(\t|\R)/ /g; to_syslog_bsd(); </Input> I tried Exec block filtering but any attempt to add xml code that filtered on the "Exec" line made all logs stop coming in. What would be the correct syntax for suppressing a username that's dedicated to cron tasks and is making the logs super noisy? Thanks all in advance. CB

Hi I downloaded and install nxlog-ce-3.0.2272_rhel8.x86_64.rpm on Centos 8 server I it is my first installation on centos 8. I used before only Centos 7 with nxlog. I copied input configuration from other server . and sending data to graylog But field FileName now unknown instead name of file . Rest of fields work excellent <Input log> Module im_file File &quot;/var/log/*&quot; SavePos TRUE ReadFromLast TRUE Exec $Message = $raw_event; Exec $FileName = file_name(); </Input>

Hello, I would like to modify the IIS logs for further transfer to the destination. Now I am parsing the IIS log with the xm_csv module, as in the template. UndefValue is disabled to not get empty. How can I interact with parsed data from w3c_parser? For example, I want to combine into a variable $request = '"' + $cs-method + ' ' + $cs-uri-stem + ' ' + $cs-version + '"'; such a value, but I get an error. When I try to write a field from w3c_parser to $raw_event, I also get an error. Any other data is added without error. For example $raw_event = $c-ip error $raw_event = $EventTime + ' ' + $http_host no error Thank you in advance!

I'm not sure it's causing a problem, but consistently nxlog will crash on Windows when making a call to stop the nxlog service with error "System Error 109 has occurred. The pipe has ended." I'd like to fix this if anyone knows of a way.

We are using NXLog CE's im_msvistalog module to forward Windows Event Logs from the Security log, with some filtering, to an external syslog server. Functionally this works well and does exactly what we need it to. The problem we are having is that nxlog.exe process often consumes rather high percentages of a workstation's CPU in bursts. Between 25 and 35 percent every few minutes, for around a minute at a time. This is generally too much of a performance hit and I need to find some way to resolve it. I have already mitigated the size of the event log file that nxlog.exe is querying from by clearing the Security log entirely, so this is happening even on a system with not more than a few dozen log entries to read from. The query itself is fairly simple, it loads all Event ID 4625 entries from the Security log (these are logon failures). It then has a single command to drop any logon failures that were initiated for a computer account instead of a user account (this is done by reading the target account trying to logon, string parsing the account username to see if the final character is a "$", which denotes a computer account, and dropping the log if the "$" is found). What can I do to mitigate the excessive CPU usage? What I have tried so far: clearing the Windows event log that nxlog is reading from to reduce the size of the data it needs to read from disk, using UDP syslog forwarding instead of TCP, removed the parsing that dropped Event Log ID 4625 entries where the target account being logged in was a computer account instead of a user account. None of this has helped. Edit to add: I did try writing out text logging instead of syslog forwarding. This worked but I am still experiencing the periodic excessive CPU consumption. The problem is likely in the im_msvistalog input module, I would assume.

Hi everyone! Has anyone ever installed or have some tips regarding a community edition package compatible with Oracle Linux 6? We've tried to use the package for REHL/CENTOS 6, installing all the dependencies, but no log is generated and sent to the syslog server. Thanks!

Hi team, from the guide below we know that the Nxlog is able to deduplicate the log by some specific fields ("CheckFields"). https://nxlog.co/documentation/nxlog-user-guide/pm_norepeat.html May I know if it is possible to set the interval for it? Let's take below configuration as example. Is it possible to set the interval = 10s, so that the log with the same fields (Hostname, SourceName, Message) will be suppressed for only every 10 seconds. This is doable from Logstash (throttle -> period), but we wanna confirm if it is capable in Nxlog as well. Thank you. <Input uds> Module im_uds UDS /dev/log </Input> <Processor norepeat> Module pm_norepeat CheckFields Hostname, SourceName, Message </Processor> <Output file> Module om_file File "/var/log/messages" </Output> <Route uds_to_file> Path uds => norepeat => file </Route>

Hi all. I'm having some windows server that are subscribed to a nxlog server, who in turn sends the windows logs to a linux/syslog server. The syslog receives all these logs as NOTICE.USER which is not too practical. I would want the nxlog to keep the criticity of the message when forwarding them. I would want nxlog to prefix the logs with the original log sender hostname so that they appear as $PROGRAM in syslog. Also, is there a way to use some criterions to send logs from nxlog to syslog using different facilities (USER, MAIL, LOCALn,...) according to some criterions (real PROGRAM value for instance)

Hello - Currently using this for Event logs: Exec $SyslogFacilityValue = 22;to_syslog_snare(); However the timestamp in the logs is local machine time and it needs to be in UTC. From searching around it looks like this is possible in EE: DateFormat YYYY-MM-DDThh:mm:ss.sUTC However I cannot find that this is feasible for CE. Is there a way with Community Edition to either manually set the timestamp to UTC (without having to know the local machine time) or, worst case scenario, is it possible to forward the log from nxlog without a timestamp at all so the received log will only have a timestamp of ingest time?
