-------------------------------------
Summary: add error stats to monitor URL
Key: FLUME-3050
URL: https://issues.apache.org/jira/browse/FLUME-3050
Project: Flume
Issue Type: Improvement
Components: Channel, Shell, Sinks+Sources
Affects Versions: v1.7.0
Reporter: Yuval Lifshitz
currently error counters are not present when getting stats. for example:
# curl http://my-flume-host:44444/metrics
{"SINK.k1":{"ConnectionCreatedCount":"1","ConnectionClosedCount":"0","Type":"SINK","BatchCompleteCount":"0","BatchEmptyCount":"4","EventDrainAttemptCount":"10","StartTime":"1485348138992","EventDrainSuccessCount":"10","BatchUnderflowCount":"1","StopTime":"0","ConnectionFailedCount":"0"},"CHANNEL.c1":{"ChannelCapacity":"1000000","ChannelFillPercentage":"0.0","Type":"CHANNEL","ChannelSize":"0","EventTakeSuccessCount":"10","EventTakeAttemptCount":"15","StartTime":"1485348138990","EventPutAttemptCount":"10","EventPutSuccessCount":"10","StopTime":"0"},"SOURCE.r1":{"EventReceivedCount":"10","AppendBatchAcceptedCount":"0","Type":"SOURCE","AppendReceivedCount":"0","EventAcceptedCount":"10","StartTime":"1485348138993","AppendAcceptedCount":"0","OpenConnectionCount":"0","AppendBatchReceivedCount":"0","StopTime":"0"}}
return only "good" stats for source, channel and sink.
to get error you need to look into the log file. this makes it hard to
integrate flume into automatic monitoring systems, NMS etc
