I want to know is possible send, with the iis log message, a custom field and value. Actually this is my config:


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 _gelf> #Module xm_syslog Module xm_gelf #Module xm_json </Extension> <Extension w3c_parser> Module xm_csv Fields date, time, s-ip, cs-method, cs-uri-stem, cs-uri-query, \ s-port, cs-username, c-ip, cs(User-Agent), cs(Referer), \ sc-status, sc-substatus, sc-win32-status, time-taken FieldTypes string, string, string, string, string, string, integer, \ string, string, string, string, integer, integer, integer, \ integer Delimiter ' ' EscapeChar '"' QuoteChar '"' EscapeControl FALSE UndefValue - </Extension> <Input in2> Module im_file File "c:\\logs\\app\\iislog\\u_extend1.log" <Exec> if $raw_event =~ /^#/ drop(); else { w3c_parser->parse_csv(); $EventTime = parsedate($date + "T" + $time + ".000Z"); } </Exec> </Input> <Output out> Module om_udp Host 172.28.36.25 Port 12201 #Exec to_syslog_snare(); OutputType GELF </Output> <Route 1> Path in2 => out </Route>

This work great but i need to add a custom and static value in the message, like : FIELD: "system" , VALUE: "program1". and this value is always the same

date, time, s-ip, cs-method, cs-uri-stem, cs-uri-query,  s-port, cs-username, c-ip, cs(User-Agent), cs(Referer), sc-status, sc-substatus, sc-win32-status, time-taken,**system**

Is this possible?

Thanks!

Hello.
Yeah, it's possible. In fact there's already an example in your code on how to add a field.
Syntax is something like it:

$fieldname = valuename;

This will do the needful.
