Hi I downloaded and install nxlog-ce-3.0.2272_rhel8.x86_64.rpm on Centos 8 server I it is my first installation on centos 8. I used before only Centos 7 with nxlog. I copied input configuration from other server . and sending data to graylog But field FileName now unknown instead name of file . Rest of fields work excellent <Input log> Module im_file File &quot;/var/log/*&quot; SavePos TRUE ReadFromLast TRUE Exec $Message = $raw_event; Exec $FileName = file_name(); </Input>
