Send file to Graylog im_file not working.

#1 jcottone 7 years ago

I have a very basic setup. I was easily able to get the general syslog functionality working.

I have been unable to get the file transport working. I've spent several days trying alternative configurations and Googling for help; all to no avail.

I also tested with om_file - trying to just grab the file and output it locally - the outcome was just a blank file.

Any help will be greatly appreciated.

Here is my config:

define ROOT C:\Program Files (x86)\nxlog
Moduledir %ROOT%\modules
CacheDir %ROOT%\data
Pidfile %ROOT%\data\nxlog.pid
SpoolDir %ROOT%\data
LogFile %ROOT%\data\nxlog.log
LogLevel INFO

<Extension gelf>
Module xm_gelf
</Extension>

<Extension _syslog>
module xm_syslog
</extension>

<Input 1>
Module im_file
file "C:\\MSSQL\\ERRORLOG"
</Input>

<Output 2>
   Module om_tcp
   Host 192.168.1.50
   Port 5550
   OutputType GELF_TCP
</Output>

There may be two reasons for that.

1. ReadFromLast for im_file defaults to FALSE. Perhaps there were no events written to your file.

2. The MSSQL ERRORLOG is UCS-2. You need the following conversion (sample taken from the manual):

<Input in>
    Module im_file
    File "C:\\MSSQL\\ERRORLOG"
    Exec $raw_event = convert($raw_event, 'UCS-2LE','UTF-8'); if $raw_event == '' drop();
</Input>
