We are building an observability product, and we see many users face issues around monitoring Kafka and async systems in general. Wanted to understand from the community here what are the common issues you face in running Kafka and how do you resolve them today? We have also jotted down some thoughts here [1] Would love to learn if any of these resonates. [1] https://signoz.io/blog/kafka-monitoring-opentelemetry/
