username: db username []
password: db password []
model: single or dynamic [single], single means all data will insert into the same collection,
    and dynamic means every event will specify collection name by event header 'collection' 
db: db name [events]
collection: default collection name, will used in single model [events]
batch: batch size of insert opertion [100]
autoWrap: indicator of wrap the event body as a JSONObject that has one field [false]
wrapField: using with autoWrap, set the field name of JSONObject [log]
timestampField: date type field that record the creating time of record,

password: required when "authenticationEnabled" is true []

flume.conf sample

agent2.sources = source2
agent2.channels = channel2
agent2.sinks = sink2

agent2.sources.source2.type = org.riderzen.flume.source.MsgPackSource
agent2.sources.source2.bind = localhost
agent2.sources.source2.port = 1985

agent2.sources.source2.channels = channel2

agent2.sinks.sink2.type = org.riderzen.flume.sink.MongoSink
agent2.sinks.sink2.host = localhost
agent2.sinks.sink2.port = 27017
agent2.sinks.sink2.model = single
agent2.sinks.sink2.collection = events
agent2.sinks.sink2.batch = 100
agent2.sinks.sink2.extraFields.ip = 192.168.1.1

agent2.sinks.sink2.channel = channel2

agent2.channels.channel2.type = memory
agent2.channels.channel2.capacity = 1000000
agent2.channels.channel2.transactionCapacity = 800
agent2.channels.channel2.keep-alive = 3

Event Headers

The sink supports some headers in dynamic model:
'db': db name
'collection' : collection name
