So I'm working on moving our logging away from SolarWinds and into nxlog. We like to punt off our logs to Splunk so that our security department can create dashboards and such for the events they care about. I've just about got the output perfect, besides ONE random extra comma and I can't figure out where it's coming from.

Here is my config:

define ROOT C:\Program Files (x86)\nxlog

define CERTDIR %ROOT%\cert Moduledir %ROOT%\modules CacheDir %ROOT%\data Pidfile %ROOT%\data\nxlog.pid SpoolDir %ROOT%\data LOGFILE %ROOT%\data\nxlog.log LogLevel INFO

<Extension syslog> Module xm_syslog </Extension>

define MonitoredEventIDs 1100, 1102, 1104, 4608, 4609, 4624, 4625, 4634, 4647, 4648,
4656, 4658, 4659, 4660, 4661, 4662, 4663, 4664, 4670, 4672,
4673, 4724, 4719, 4720, 4722, 4723, 4724, 4725, 4726, 4727,
4728, 4729, 4731, 4732, 4733, 4734, 4735, 4737, 4738, 4739,
4740, 4766, 4767, 4768, 4776, 4781, 4801, 4825, 4907, 5136,
5137, 5139, 5141, 5145, 6416, 13002, 13003, 18500, 18502, 307

<Input eventlog> Module im_msvistalog <QueryXML> <QueryList> <Query Id="0"> <Select Path="Security"></Select> <Select Path="Microsoft-Windows-PrintService/Operational"></Select> </Query> </QueryList> </QueryXML> <Exec> if $EventID NOT IN (%MonitoredEventIDs%) drop(); </Exec> </Input>

<Input GFI> Module im_msvistalog <QueryXML> <QueryList> <Query Id="0"> <Select Path="GFI EndPointSecurity">*</Select> </Query> </QueryList> </QueryXML> </Input>

<Output out> Module om_udp Host 10.1.0.1 Port 514 Exec to_syslog_snare();$raw_event = replace($raw_event, "\t", ","); </Output>

<Route> Path eventlog, GFI => out </Route>

That creates this beautiful output in Splunk, except for the random extra comma before 'An account was logged off.' This single extra comma is throwing off the parsing of the logs that our customer receives and I need to get rid of it... Any advice?
