The Burrow 1.0

The Burrow is a monitoring tool that keeps the track of consumer lag. Any user interface is not provided by this tool but it provides several HTTP links to get information about consumer groups and Kafka clusters. On the other hand, it also has a notification functionality which basically notifies the user via email, message or any acknowledgment technique whenever any certain criteria are met by any consumer group.

The Burrow supports configurations given in multiple different formats. This includes TOML, JSON, and YAML.

It also contains several subsystems which are given below:

    • Clusters: This component is used to update the topics list periodically and for each partition whatever the last committed offset is.

    • Evaluator: it evaluates the status of consumers by fetching the stored information that whether it’s a slow rate of consuming messages

    • Notifier: it sends notification after checking the status of consumer groups.

    • Consumers: This subsystem is used to fetch information about consumers like consumers lags etc.

    • Storage: this part is used for the storage of information

    • HTTP server:  fetch information about a cluster and consumers by providing HTTP requests
