MQ Viewer

MQ Viewer enables direct connection to message brokers to retrieve messages from selected queues or topics. It normalizes broker metadata and presents messages with timestamps, headers, and payloads. The tool supports real-time streaming or historical fetch within a defined window, enabling developers to reproduce issues, verify delivery semantics, and inspect payload shapes. By supporting multiple protocols (AMQP-based and Kafka-like), it provides a unified view across environments. Users can specify access credentials, broker type, and target queue, then request a bounded set of messages for analysis. This reduces guesswork during incident response and improves audit traceability.

Internally, the tool connects to the broker, subscribes or polls for messages, and applies filters on timestamps, headers, or keys. It attempts to decode payloads using common formats, such as JSON or Base64, and then displays a readable sample while preserving raw payload when decoding fails. The system also exports message metadata (timestamps, headers) and payload in structured formats, enabling downstream processing in analytics pipelines. Developers benefit from immediate visibility into message shapes, payload entropy, and anomalies in header fields, while operations teams gain an auditable trail of delivered messages across services.

Differentiators include cross-broker compatibility, integrated decoding, and export-ready outputs without requiring separate tooling. Use cases include debugging failed deliveries, validating event-driven flows, and performing post-incident analysis. The tool is designed for engineering, operations, and QA teams that work with distributed messaging architectures and need a reproducible, shareable snapshot of message traffic.
