MRTR is a diagnostic and testing utility designed to measure the round‑trip time of messages within IBM MQ environments. The utility sends a message through a defined MQ path and waits for the corresponding response, allowing precise measurement of how long the complete request‑and‑reply cycle takes. This provides visibility into MQ latency, responsiveness, and path integrity without relying on business applications. MRTR operates at the infrastructure level and is typically used for testing, validation, troubleshooting, and performance analysis of MQ configurations. It helps confirm that MQ routes, channels, and queues behave as expected under controlled conditions.
