Shipping from Logstash to Kafka and analysing with Cloudflare Workers

This blog post provides a step-by-step guide on how to set up a Kafka cluster using Upstash, configure Logstash to ship logs to the Kafka cluster, and use Cloudflare Workers for basic message analysis. It begins by demonstrating the creation of a serverless Kafka cluster in the Upstash Console and configuring Logstash to read from a sample text file, sending each line to the Kafka topic. The post then illustrates how to use Cloudflare's playground tool to consume messages from Kafka and perform simple word count analytics using a Cloudflare Worker. The example concludes by highlighting the simplicity of this setup for beginners, while noting that Logstash can handle more complex scenarios involving multiple log sources and Cloudflare Workers can further process and distribute analyzed data. The author encourages readers to provide feedback and hints at exploring more advanced use cases in future posts.
