Class MapEntriesAppendingMarker

java.lang.Object
net.logstash.logback.marker.LogstashMarker
net.logstash.logback.marker.MapEntriesAppendingMarker
All Implemented Interfaces:
Serializable, Iterable<org.slf4j.Marker>, StructuredArgument, org.slf4j.Marker
public class MapEntriesAppendingMarker extends LogstashMarker implements StructuredArgument
A Marker OR StructuredArgument that appends entries from a Map into the logging event output.

When writing to the JSON data (via ArgumentsJsonProvider or LogstashMarkersJsonProvider):

When writing to a String (when used as a StructuredArgument to the event's formatted message), String.valueOf(Object) is used to convert the map to a string.

For example, if the message is "mymessage {}", and map argument contains is 

 
 name1= a String "value1",
 name2= an Integer 5,
 name3= an array containing [1, 2, 3],
 name4= a map containing  name5=6
Then the message, name1, name2, name3, name4 fields will be added to the json for the logstash event.

For example: 

 {
     "message" : "mymessage [name1=value1,name2=5,name3=[b...,name4=[name5=6]]",
     "name1"   : "value1",
     "name2"   : 5,
     "name3"   : [1, 2, 3],
     "name4"   : { "name5" : 6 }
 }
