A simple UI for monitoring Apache Kafka topics and their state.

Kafka Topic View

Kafka Topic View is a simple UI for monitoring Kafka topics and their state. It lists all Kafka brokers, and the partitions assigned to them. The partitions are listed as squares with colors from green (the partitions is in good shape) to red (the partition is under-replicated or offline). When you hover over the partition square, a tooltip shows the details of the partition.

TODO

• Configure refresh interval in the UI
• Add SASL support
• Better logging
• CI build

Usage

Locally

Run the binary and use the configuration options to configure where it listens and how it connects to Kafka:

Option	Description	Default
--listen-addr	The address where the HTTP Server runs	0.0.0.0:8080
--fetch-interval	The interval at which to fetch the new topic data (default 1m0s)	1m0s
--bootstrap-server	Comma separate list of Kafka Brokers to connect to
--kafka-version	Version of the Kafka cluster	2.5.0
--tls-ca-file	File with the CA certificate for server authentication
--tls-cert-file	File with the client certificate for client authentication
--tls-insecure-skip-verify	Skip TLS verification when connecting to the Kafka brokers. Use at your own risk!
--tls-key-file	File with the key for client authentication
--verbose	Turn on verbose logging	false
--sarama-verbose	Turn on verbose logging int he Sarama Kafka client	false

In Kubernetes with Strimzi

Edit the deployment-strimzi.yaml file to match your Strimzi cluster setup (secret names, cluster name, bootstrap servers etc.) and deploy it to Kubernetes:

kubectl apply -f deployment-strimzi.yaml

Use kubectl proxy or kubectl port-forward to access the UI.

Build

Build the Golang backend first:

go build

If needed, build also the container with the backend and UI:

docker build -t <org>/<image>:<tag> ./
