Summary: Metrics for Flafka components
Key: FLUME-2562
URL: https://issues.apache.org/jira/browse/FLUME-2562
Project: Flume
Issue Type: Improvement
Reporter: Gwen Shapira
Kafka source, sink and channel should have metrics. This will help us track
down possible issues or performance problems.
Here are the metrics I came up with:
kafka.next.time - Time spent waiting for events from Kafka (source and channel)
kafka.send.time - Time spent sending events (channel and sink)
kafka.commit.time - Time spent committing (source and channel)
events.sent - Number of events sent
events.rollback - Number of event rolled back (channel) or number of rollback
calls (sink)
kafka.empty - Number of times backing off due to empty kafka topic (source)
