------------------------------------
Summary: De-couple "Spout Lag" metrics on Storm UI from Kafka
Spout and StormKafkaMonitor
Key: STORM-2783
URL: https://issues.apache.org/jira/browse/STORM-2783
Project: Apache Storm
Issue Type: Improvement
Components: storm-core
Affects Versions: 2.0.0, 1.1.1
Reporter: Stephen Powis
As a developer of a spout, I'd love to be able to publish lag metrics to the
storm UI. After digging into the source code for how the UI interacts with
storm-kafka-monitor to get these metrics, it appears to be strongly coupled. I
believe that the concept of "Spout Lag" extends beyond the scope of just
consuming from Kafka.
I'd like to propose the idea of restructuring how these metrics are queried by
StormUI to a way that allows developers of other spouts to be able to "plug
into" the UI. The easiest way that springs to mind is to provide an interface
that allows developers to code against.
