{  
codec =\> multiline {  
pattern =\> "(^%{TOMCAT\_DATESTAMP})|(^%{CATALINA\_DATESTAMP})"  
negate =\> true

}  
}

No. codecs are used in inputs and outputs, not filters.

Configuration looks good after adding codec inside amazon\_es, But it didnt merge the lines . Does codec -\> multiline is supported for amazon\_es plugin ?  
amazon\_es {  
codec =\> multiline {  
pattern =\> "^%{TIMESTAMP\_ISO8601}"  
negate =\> true  
what =\> "previous"  
auto\_flush\_interval =\> 5  
}  
hosts =\>....  
}
