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 # ######################################## Module xm_gelf Module im_file File "/var/log/logfile1.txt" Module im_file File "/var/log/logfile2.txt" Module om_udp Host 192.168.0.100 Port 12201 OutputType GELF Module om_udp Host 192.168.0.100 Port 12203 OutputType GELF ######################################## # Routes # ######################################## Path APP1=> Graylog1 Path APP2 => Graylog2 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?

Hi,

I don't see any obvious error here.

Are you sure your Graylog instance is listening on both ports that you declared here? I'd suggest checking if both UDP connections are established at all.
