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

---

• Topics, partitions, log sizes, and partition leaders

---

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

---

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

---

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

---

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:

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:
