Hubble can answer questions such as: Service dependencies & communication map What services are communicating with each other? How frequently? What does the service dependency graph look like? What HTTP HTTP calls are being made? What Kafka topics does a service consume from or produce to? Network monitoring & alerting Is any network communication failing? Why is communication failing? Is it DNS? Is it requests? Application monitoring What is the rate of 5xx or 4xx HTTP response codes for a particular service or across all clusters? What is the 95th and 99th percentile latency between HTTP requests and responses
