I am attempting to use NXLog in conjunction with Graylog's Sidecar Collector to send data to my Graylog server. I have been able to successfully telnet to my Graylog server through port 5044, so I know it is not a firewall issue, yet I keep getting these errors in my NXLog error log:

2017-11-08 14:37:09 ERROR om_tcp detected a connection error;Connection reset by peer 2017-11-08 14:37:25 ERROR om_tcp detected a connection error;End of file found

And nothing is being received by my Graylog server.

Here is my generated NXLog configuration:

define ROOT /usr/bin

<Extension gelf> Module xm_gelf </Extension>

User nxlog Group nxlog

Moduledir /usr/libexec/nxlog/modules CacheDir /var/spool/collector-sidecar/nxlog PidFile /var/run/graylog/collector-sidecar/nxlog.pid

define LOGFILE /var/log/graylog/collector-sidecar/nxlog.log LogFile %LOGFILE% LogLevel DEBUG

<Extension logrotate> Module xm_fileop <Schedule> When @daily Exec file_cycle('%LOGFILE%', 7); </Schedule> </Extension>

<Input 59fcda86ccba8e2573422cb4> Module im_file File '/var/log/httpd/syriac_access_log' PollInterval 1 SavePos True ReadFromLast True Recursive True RenameCheck False Exec $FileName = file_name(); # Send file name with each message </Input>

<Output 59fcda56ccba8e2573422c80> Module om_tcp Host graylog.library.vanderbilt.edu Port 5044 OutputType GELF_TCP Exec $short_message = $raw_event; # Avoids truncation of the short_message field. Exec $gl2_source_collector = '485f3ca7-ca1e-4959-be00-117a50e2b1db'; Exec $collector_node_id = 'graylog-collector-sidecar'; Exec $Hostname = hostname_fqdn(); </Output>

<Route route-0> Path 59fcda86ccba8e2573422cb4 => 59fcda56ccba8e2573422c80 </Route>

I would appreciate any advice or guidance. Thank you!
