Kafka Tool also allows you to view the offsets of the Apache Storm's Kafka spouts. The Storm Kafka spouts store their offset in a different Zookeeper location and in a different format than the regular Kafka consumers. The Storm Kafka consumers have a different icon from the regular Kafka consumers, so they can quickly be spotted in the Browser Tree.
By default the Storm Kafka spout stores the offset at the root (/) of the Zookeeper hierarchy. However, you can specify a custom path where to store the consumer offset by specifying it in the SpoutConfig constructor. If you are storing the consumer offsets in a non-standard location, you can tell Kafka Tool where they are located. This can be done on Tools/Settings/Storm screen.
