Monitoring UI for Apache kafka - kafka manager vs kafka monitor
I am new to kafka. We want to monitor and manage kafka topics. We tried different open source monitoring tools like
Both tools are good. But we are unable to make a decision which should be included in our deployment stack. Which one is better and why, and in which scenario?
'kafka manager' from yahoo looks the older one and 'kafka monitor' from LinkedIn is newer one
Kafka Monitor- 
Answer
Lenses
Lenses (ex Landoop) enhances Kafka with User Interface, streaming SQL engine and cluster monitoring. It enables faster monitoring of Kafka data pipelines.
They provide a free all-in-one docker (Lenses Box) which can serve a single broker for up to 25M messages. Note that this is recommended for development environments.
Cloudera SMM
Streams Messaging Manager is the solution for monitoring and managing clusters running Cloudera or Hortonworks kafka. It also comes with replication capability.
Confluent
Another option is Confluent Enterprise which is a Kafka distribution for production environments. It also includes Control Centre, which is a management system for Apache Kafka that enables cluster monitoring and management from a User Interface.
Yahoo CMAK (Cluster Manager for Apache Kafka, previously known as Kafka Manager)
Kafka Manager or CMAK is a tool for monitoring Kafka offering less functionality compared to the aforementioned tools.
KafDrop
KafDrop is a UI for monitoring Apache Kafka clusters. The tool displays information such as brokers, topics, partitions, and even lets you view messages. It is a lightweight application that runs on Spring Boot and requires very little configuration.
LinkedIn Burrow
Burrow is a monitoring companion for Apache Kafka that provides consumer lag checking as a service without the need for specifying thresholds. It monitors committed offsets for all consumers and calculates the status of those consumers on demand. An HTTP endpoint is provided to request status on demand, as well as provide other Kafka cluster information. There are also configurable notifiers that can send status out via email or HTTP calls to another service.
Kafka Tool
Kafka Tool is a GUI application for managing and using Apache Kafka clusters. It provides an intuitive UI that allows one to quickly view objects within a Kafka cluster as well as the messages stored in the topics of the cluster. It contains features geared towards both developers and administrators.
If you cannot afford licenses, then go for Yahoo Kafka Manager, LinkedIn Burrow or KafDrop. Confluent's and Landoop's products are the best out there, but unfortunately, they require licensing.
