Kafka Web Console

Kafka Web Console is a Java web application for monitoring Apache Kafka. With a modern web browser, you can view from the console:

  • Registered brokers

brokers

  • Topics, partitions, log sizes, and partition leaders

topics

  • Consumer groups, individual consumers, consumer owners, partition offsets and lag

topic

  • Graphs showing consumer offset and lag history as well as consumer/producer message throughput history.

topic

  • Latest published topic messages (requires web browser support for WebSocket)

topic feed

Furthermore, the console provides a JSON API described in RAML. The API can be tested using the embedded API Console accessible through the URL http://[hostname]:[port]/api/console.

Requirements

  • Play Framework 2.2.x
  • Apache Kafka 0.8.x
  • Zookeeper 3.3.3 or 3.3.4

Deployment

Consult Play!'s documentation for deployment options and instructions.

Getting Started

  1. Kafka Web Console requires a relational database. By default, the server connects to an embedded H2 database and no database installation or configuration is needed. Consult Play!'s documentation to specify a database for the console. The following databases are supported:

    • H2 (default)
    • PostgreSql
    • Oracle
    • DB2
    • MySQL
    • Apache Derby
    • Microsoft SQL Server

    Changing the database might necessitate making minor modifications to the DDL to accommodate the new database.

  2. Before you can monitor a broker, you need to register the Zookeeper server associated with it:

register zookeeper

Filling in the form and clicking on Connect will register the Zookeeper server. Once the console has successfully established a connection with the registered Zookeeper server, it can retrieve all necessary information about brokers, topics, and consumers:
