This is debug log output from filebeat. It shows what filebeat is doing in the background. Were you looking for something specific?

i am working with filebeat to process the log files and send the output to either elasticsearch or logstash or a file.

But when I run the filebeat, nothing happens. Except that the above mentioned logs lines were filling.

start\_position =\> "beginning"  
codec =\> multiline {  
pattern =\> "^%{TIMESTAMP\_ISO8601} "  
negate =\> true  
what =\> previous  
}  
}  
}

filter {  
grok {  
match =\> { 'message' =\> '%{TIMESTAMP\_ISO8601}%{SPACE}%{WORD:Level}%{SPACE}%{GREEDYDATA:DatabaseMessage}' }
