Good Day, 

I installed nxlog to ready to ready my mssql errorlog file, and send it to graylog server, but for some reason the message is not coming complete,

here is my conf

I omitted the rest because it just the default configuration file 

<Extension charconv> 
   Module      xm_charconv
   AutodetectCharsets iso8859-2, utf-8, utf-16, utf-32,UCS-2LE

<Extension gelf>
   Module xm_gelf

<Input mssql_errorlog>
   Module      im_file
   File        "D:\Program Files\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQL\Log\ERRORLOG"

<Output graylog_udp>
   Module om_udp
   Port 12202
   OutputType    GELF_UDP

<Route graylog_route_mssql_errorlog>
   Path mssql_errorlog => graylog_udp_204

This is the line in my ERRORLOG

2023-05-26 10:00:13.50 Logon       Login failed for user 'localnet\sqljobs'. Reason: Could not find a login matching the name provided. [CLIENT: <local machine>]

And this is the message i get in graylog

And this is the result parsed by graylog

message : 2023-05-26 10:00:13.50 Logon

Any one has any idea what could be wrong?
