I've been using NXLog to monitor a simple log file from an application and send it to Graylog using GELF. Very simple, very efficient, and it works just like I want it to. Now I want to monitor a 2nd log file from another application and send that to a separate input in Graylog (also using GELF). I thought it would be quick and simple to add the 2nd log file as another om_file imput and add a 2nd output to route the log file to. But for some reason, I just can't get the 2nd input/output to work. Here is my nxlog.conf file:

########################################
User nxlog
Group nxlog

LogFile /var/log/nxlog/nxlog.log
LogLevel INFO

########################################
# Modules                              #

<Input APP1>
    Module      im_file
    File        "/var/log/logfile1.txt"
</Input>

<Input APP2>
    Module      im_file
    File        "/var/log/logfile2.txt"
</Input>

<Output Graylog1>
    Module      om_udp
    Host        192.168.0.100
    Port        12201
    OutputType  GELF
</Output>

<Output Graylog2>
    Module      om_udp
    Host        192.168.0.100
    Port        12203
    OutputType  GELF
</Output>


########################################
# Routes                               #
########################################
<Route graylog_1>
    Path        APP1=> Graylog1
</Route>
<Route graylog_2>
    Path        APP2 => Graylog2
</Route>

What I've found is that if I also route the logfile2.txt to Graylog1, it works just fine. So both log files can be sent to Graylog1. But when I add that 2nd output, Graylog2, and route logfile2.txt to it, I never get any of those messages in Graylog. I know this isn't a Graylog forum, but am I missing something in my nxlog.conf or should I be looking more at the Graylog server?
