Hi, I'm trying to use nxlog to to extract three metrics from a .set file. My OS is Windows 10. I edited the .conf file in "C:\Program Files (x86)\nxlog\conf" and it looks like this: Panic Soft #NoFreeOnExit TRUE 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 json> Module xm_json </Extension> <Extension sikora> Module xm_set Fields $Nominal, $PlusTol, $Oval # fields of interest (metrics) FieldTypes string, string, string # type of variable Delimiter ; EscapeControl FALSE </Extension> <Input sikora_logs> Module im_file File "C:\Users\50051145\Desktop\nx_log\\*.set" # imput file #ReadFromLast True #Recursive True #SavePos True ReadFromLast False Recursive False SavePos False &lt;Exec&gt; if $raw_event =~ /^Macrosezione : (.+)/ # creazione variabile { # create_var('macrosection'); # set_var('macrosection', $1); # drop(); # } sikora-&gt;parse_set(); delete($EventReceivedTime); delete($SourceModuleName); delete($SourceModuleType); if $raw_event =~ /^Operatore / { # variable definition for the if not defined get_var('start_time') # timestamp { # log_debug(&quot;parsed_time: &quot; + strptime($time, &quot;%d/%m/%Y %I:%M:%S&quot;)); # create_var('start_time'); # set_var('start_time', strptime($time, &quot;%d/%m/%Y %I:%M:%S&quot;)); drop(); } else { if get_var('start_time') != strptime($time,&quot;%d/%m/%Y %I:%M:%S&quot;) { log_debug(&quot;old_time: &quot; + get_var('start_time')); log_debug(&quot;new_time: &quot;, $time); set_var('start_time', strptime($time,&quot;%d/%m/%Y %I:%M:%S&quot;)); drop(); } } } $time = (integer(get_var('start_time')) / 1000000 + integer($time)) * 1000; # formula to convert timestamp in milliseconds $pressure = integer($pressure); $macrosection = get_var('macrosection'); $nominal = get_var('nominal'); $type = get_var('type'); to_json(); &lt;/Exec&gt; </Input> <Output out> Module om_file # CreateDir TRUE # File "C:\Users\50051145\Desktop\temp" + $fileName # output file </Output> <Route 1> Path sikora_logs => out </Route> When I run the program I expect an output file in a folder on my desktop "C:\Users\50051145\Desktop\temp" but I get nothing.

It appers that xm_set.dll library is missing, "The specified module could not be found". I found out in "C:\Program Files (x86)\nxlog\modules\extension" that nxlog doesn't come with a .set library. How can I add this library ? Thank you

Hello All, I have a huge .csv file, this contains logs from Service Now instance. I have the following nxlog configuration file. But when i run the parser, error file i generate exceeds more than 1 GB. The source file itself is only about 225 MB. Please set the ROOT to the folder your nxlog was installed into, otherwise it will not start. #define ROOT C:\Program Files\nxlog 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 <Extension multiline> Module xm_multiline HeaderLine /^\d{1,2}/\d{1,2}/\d{4}\s/ </Extension> <Extension json> Module xm_json </Extension> <Extension csv> Module xm_csv Fields $Created,$Level,$Message,$Source,$CreatedBy FieldTypes string, string, string, string, string </Extension> <Extension syslog> Module xm_syslog </Extension> <Input eventlog> Module im_msvistalog ReadFromLast TRUE SavePos TRUE Query <QueryList> <Query Id="0"> <Select Path="Security">[System[(EventID=4768)]]</Select> <Select Path="Security">[System[(EventID=4769)]]</Select> <Select Path="Security">[System[(EventID=4771)]]</Select> <Select Path="Security">[System[(EventID=4624)]]</Select> <Select Path="Security">[System[(EventID=4625)]]</Select> <Select Path="Security">[System[(EventID=4634)]]</Select> <Select Path="Security">[System[(EventID=4647)]]</Select> <Select Path="Security">[System[(EventID=4648)]]</Select> <Select Path="Security">[System[(EventID=4656)]]</Select> <Select Path="Security">[System[(EventID=4719)]]</Select> <Select Path="Security">[System[(EventID=4720)]]</Select> <Select Path="Security">[System[(EventID=4722)]]</Select> <Select Path="Security">[System[(EventID=4723)]]</Select> <Select Path="Security">[System[(EventID=4724)]]</Select> <Select Path="Security">[System[(EventID=4725)]]</Select> <Select Path="Security">[System[(EventID=4726)]]</Select> <Select Path="Security">[System[(EventID=4727)]]</Select> <Select Path="Security">[System[(EventID=4728)]]</Select> <Select Path="Security">[System[(EventID=4729)]]</Select> <Select Path="Security">[System[(EventID=4730)]]</Select> <Select Path="Security">[System[(EventID=4731)]]</Select> <Select Path="Security">[System[(EventID=4732)]]</Select> <Select Path="Security">[System[(EventID=4733)]]</Select> <Select Path="Security">[System[(EventID=4734)]]</Select> <Select Path="Security">[System[(EventID=4735)]]</Select> <Select Path="Security">[System[(EventID=4737)]]</Select> <Select Path="Security">[System[(EventID=4738)]]</Select> <Select Path="Security">[System[(EventID=4739)]]</Select> <Select Path="Security">[System[(EventID=4741)]]</Select> <Select Path="Security">[System[(EventID=4742)]]</Select> <Select Path="Security">[System[(EventID=4743)]]</Select> <Select Path="System">[System[(EventID=7036)]]</Select> <Select Path="Application">[System[(EventID=18454)]]</Select> <Select Path="Application">[System[(EventID=18456)]]</Select> </Query> </QueryList> Exec to_json(); </Input> <Input filein> Module im_file File 'e:\ServiceNow\agent\export\snow_log.csv' InputType multiline ReadFromLast FALSE SavePos FALSE &lt;Exec&gt; # Ignore top line if $raw_event =~ /Created,Level,Message,Source,Created by/ drop(); if $raw_event =~ /Warning/ drop(); if $raw_event =~ /Information/ drop(); # Convert Newline and Tab to printed character #$raw_event =~ s/\R/\\r\\n/g; #$raw_event =~ s/\t/\\t/g; $raw_event = replace($raw_event,&quot;\n&quot;, &quot; &quot;); $raw_event = replace($raw_event,&quot;\r&quot;, &quot; &quot;); $raw_event = replace($raw_event,&quot;\t&quot;, &quot; &quot;); $SourceName = 'SNOWLogs'; # Parse $raw_event as CSV csv-&gt;parse_csv(); # Convert to JSON to_json(); &lt;/Exec&gt; </Input> <Output fileout> Module om_tcp Host logger Port 5140 #Exec to_syslog_bsd(); </Output> <Output out> Module om_tcp Host logger Port 5140 </Output> <Route r1> Path eventlog => out </Route> <Route parse_xml> Path filein => fileout </Route> For few lines it reads the data properly, but in some lines, it does not read the complete data. I am also trying to drop off unwanted data like information or warning, just to ensure i collect only Error information. But still it does not help. Error information from the file is very limited, so that I can reduce the amount of data to be ingested into ELK.

This is the Log: <13>Sep 4 16:07:23 Firewall: LEEF:1.0|FORCEPOINT|Firewall|1.1.1|Connection_Discarded|src=122.1.1.1 EventReceivedTime=2019-09-04 16:07:23 SourceModuleName=****** SourceModuleType=im_tcp LEEFVersion=<1> LEEF:0.0 Vendor=FORCEPOINT vSrcName=Firewall Version=1.1.1 EventID=Connection_Discarded devTimeFormat=MMM dd yyyy HH:mm:ss devTime=2019-09-04 16:07:23 proto=1 dstPort=80 srcPort=53438 dst=192.1.1.1 sender=services.fw.mi01.custom.cloud node 1 action=Discard the system sets the value of $Sender like this: $Sender = services.fw.mi01.custom.cloud node 1 action=Discard.txt but I need instead the system to set $Sender this way, only up to "node 1": $Sender = services.fw.mi01.custom.cloud node 1.txt I thought about using a regex to extrapolate the value I need, but it doesn’t work. this one: <Exec> if $Sender =~ /(?<=sender=).[^\t]+/g; $Sender = $1 </Exec> Can I do this thing? If so, what should I do? Thank you Antonio

Hello, I'm experiencing an issues with the community edition. Once you power off the log collection server, the nxlog client agent (for windows) will drop the connection, and stop sending UDP packets after the log collection server is back online. Restarting the windows agent starts resolves the issue. Is there a solution for this besides restarting the windows service every so often to ensure the agent is always sending logs? Thanks

I'm attempting to enrich some Windows event logs with "ClientMachine" which needs to equal the hostname. I'm having issues with only some logs coming through with this enriched fields, and others do not contain the ClientMachine enrichment. My config is below. Any help would be greatly appreciated. Panic Soft define ROOT C:\Program Files\nxlog #ModuleDir %ROOT%\modules #CacheDir %ROOT%\data #SpoolDir %ROOT%\data #define CERTDIR %ROOT%\cert define CONFDIR %ROOT%\conf Note that these two lines define constants only; the log file location is ultimately set by the LogFile directive (see below). The MYLOGFILE define is also used to rotate the log file automatically (see the _fileop block). define LOGDIR %ROOT%\data define MYLOGFILE %LOGDIR%\nxlog.log By default, LogFile %MYLOGFILE% is set in log4ensics.conf. This allows the log file location to be modified via NXLog Manager. If you are not using NXLog Manager, you can instead set LogFile below and disable the include line. LogFile %MYLOGFILE% <Extension _syslog> Module xm_syslog </Extension> <Input in> Module im_msvistalog </Input> <Output out> Exec $ClientMachine = hostname_fqdn(); Module om_tcp Host 192.168.1.20 Port 11105 Exec to_syslog_snare(); </Output> <Route 1> Path in => out </Route>

Hi all, I'm using nxlog to send CAS audit log to our syslog server. Each entry in the text file looks similar to this as below: 2019-08-28 14:33:58,959 INFO [org.apereo.inspektr.audit.support.Slf4jLoggingAuditTrailManager] - Audit trail record BEGIN ============================================================= WHO: user1 WHAT: ST-65-eMcuA7IeZWYUYPldhgaT-11 for https://test.com.vn/news/ ACTION: SERVICE_TICKET_CREATED APPLICATION: CAS WHEN: Wed Aug 28 14:33:58 ICT 2019 CLIENT IP ADDRESS: x.x.x.x SERVER IP ADDRESS: x.x.x.x ============================================================= I want to combine these multiple lines to 1 line and I've read some of the documentation on nxlog's website regarding multiline but haven't found a specific config to put them all in 1 entry with a syslog header. Is there any solution for nxlog conf to work with this kind of multiline message? Thanks

Hi, I’m trying to configure the windows event forwarding from a Windows machine to the nxlog machine using the wseventing module and we want to use the http protocol on port 80. The two machines are on the same domain, so with the kerberos already configured, but Nxlog gives me the following error: 2019-08-28 09:30:45 ERROR https is required for im_wseventing without kerberos support at C:\Program Files\nxlog\conf\nxlog.conf:156 this is the configuration of nxlog entered as described on the documentation: <Input wseventing> Module im_wseventing Address http://nxlog.domain.cloud:80/wsman ListenAddr 0.0.0.0 Port 80 SubscriptionName test Exec log_info(to_json()); <QueryXML> <QueryList> <Query Id="0" Path="Application"> <Select Path="Application"></Select> <Select Path="Security"></Select> <Select Path="Setup"></Select> <Select Path="System"></Select> <Select Path="ForwardedEvents"></Select> <Select Path="Windows PowerShell"></Select> </Query> </QueryList> </QueryXML> </Input> Being both machines on the same domain, seems a strange mistake, do you have any ideas?

Hello! First time nxlog user here. Looking at the docs: https://nxlog.co/documentation/nxlog-user-guide-full#om_http_config It would seem to indicate the availability of a ProxyAddress directive but when I populate the nxlog.conf file with one, I receive an error that the ProxyAddress keyword is invalid: 2019-08-27 17:34:40 ERROR invalid keyword: ProxyAddress at C:\Program Files (x86)\nxlog\conf\nxlog.conf:91 2019-08-27 17:34:40 ERROR module 'http' has configuration errors, not adding to route '1' at C:\Program Files (x86)\nxlog\conf\nxlog.conf:96 2019-08-27 17:34:40 WARNING not starting unused module http 2019-08-27 17:34:40 INFO nxlog-ce-2.10.2150 started Can anyone point me in the right direction on this one?

The endpoint I will be sending logs to expects this format: { "timestamp":"2019-08-06T19:00:03Z", "body":"This is a sample body", "attributes":{ "token":"some token value", "log_type":"error", "(extensible keys)":"(string value)" } } I need to convert Windows eventlogs to the target format and I'm having an issue creating "attributes."

Hello everyone an old employee setup nxlog with server 2008 R2. Since that is coming to an end or the support is I am trying to setup nxlog on a 2016 server. I went ahead and downloaded the client and copied the conf file over from the old server. I then looked for how it was deployed. From what I can see it was deployed using a gpo under the event forwarding section and Configure target subscription manager. I went into this location and changed the information from the old server to the new so instead of log2 it is now log3 with all the same parameters. I then waited for a couple of hours since it takes around an hour for the machine to check the gpo's. I even restarted some machines. After this was done I caused some Software restriction Policy alerts that will email us when on the old server. When doing this on the new nothing happens. I also log into the server and start an instance of wireshark. There are some logs coming into the server but not the amount that was coming into the old server in the same time. I then swith the name back in the gpo from log3 to log2. After this is done in about an hour time all the Software restriction Policy alerts start coming in to our email. I then check wireshark. In a minutes time with the new (relog3) server I will get around 200 logs. With the old now (relog2) I am over 1000 in the same time. For some reason when making the change in the gpo it seems like the computers are holding the logs and don't want to send to the new location, then when changing it back it send the logs that were held. Any idea on what is going on here?

Hello guys, please help to split MESSAGE to seperate events with syslog_bsd headers. config example: <Extension csv_parser> Module xm_csv Fields DisplayName, EmailAddress, Department, Title, Description, SamAccountName,EmployeeNumber,PasswordLastSet,LastLogonDate,enabled FieldTypes string,string,string,string,string,string,string,string,string,string </Extension> Exec $msg1 = ($SamAccountName + " | -DisplayName | " + $DisplayName); Exec $msg2 = ($SamAccountName + " | -EmailAddress | " + $EmailAddress); Exec $msg3 = ($SamAccountName + " | -Department | " + $Department); Exec $msg4 = ($SamAccountName + " | -Title | " + $Title); Exec $msg5 = ($SamAccountName + " | -Description | " + $Description); Exec $msg6 = ($SamAccountName + " | -SamAccountName | " + $SamAccountName); Exec $msg7 = ($SamAccountName + " | -EmployeeNumber | " + $EmployeeNumber); Exec $msg8 = ($SamAccountName + " | -PasswordLastSet | " + $PasswordLastSet); Exec $msg9 = ($SamAccountName + " | -LastLogonDate | " + $LastLogonDate); Exec $msg10 = ($SamAccountName + " | -enabled | " + $enabled); Exec $raw_event = $msg1 + "\n" + $msg2 + "\n" + $msg3 + "\n" + $msg4 + "\n" + $msg5 + "\n" + $msg6 + "\n" + $msg7 + "\n" + $msg8 + "\n" + $msg9 + "\n" + $msg10 + "\n"; So the ouput like: Administrator | -DisplayName | Administrator | -EmailAddress | admin@gmail.com Administrator | -Department | Administrator | -Title | Administrator | -Description | Built-in account for administering the computer/domain Administrator | -SamAccountName | Administrator Administrator | -EmployeeNumber | Administrator | -PasswordLastSet | 2/21/2019 1:57:37 PM Administrator | -LastLogonDate | 2/21/2019 2:08:51 PM Administrator | -enabled | True How to add syslog header <PRI>TIMESTAMP HOSTNAME TAG[PID]: before each line and send to syslog as seperate messages?

Hello. We plan on using the im_file module to ingest W3C IIS logs. We will use the command script provided in the user manual in section 69.7 as we have many IIS servers and the logs are not all in the same place. We use NXLog Manager to manage all of our agents. When attempting to create the module for the agent within NXLog Manager, we are being forced to input something for the 'File' parameter. Yet when we do the 'include_stdout' directive as shown in the manual, that creates the 'File' parameter based on what the script finds so we don't want the NXLog Manager defining that parameter. How do we tell NXLog Manager to skip that parameter? We don't want to have to manually update log4ensics.conf on each of these servers. Thank you.
