I have a gelf formatted log file and i push log from logstash to graylog. My logs get transfer but fields are displayed in wrong manner. example in my log version was 1.1 and level was 4 but i get as 1.0 and 6 respectively.
{ “version”:“1.1”,“host”:"*****",“level”:4,“timestamp”:1531426492,“short_message”:“Starting MERGE”,“full_message”:“123456.csv”,"_process_log_id":110,"_process_id":7,"_file":“part-00002-2934af0b-e1cc-408.csv”,"_process":“hello”}
