#Storm Kafka Monitor

Tool to query kafka spout lags and show in Storm UI

Usage

This tool provides a way to query kafka offsets that the spout has consumed successfully and the latest offsets in kafka. It provides an easy way to see how the topology is performing. It is a command line interface called storm-kafka-monitor in the bin directory. The results have also been included in storm ui on the topology page. It supports both new and the old kafka spout. Please execute the command line without any options to see usage.

$STORM_HOME_DIR/bin/storm-kafka-monitor

Future Work

The offset lag calculation support for trident kafka spouts will be added soon.
