Amazon MQ Service Monitoring

Amazon MQ Service - Overview

Amazon MQ is a fully managed message broker service that supports popular messaging protocols like ActiveMQ and RabbitMQ, facilitating seamless communication between distributed applications, microservices, and IoT devices.

Monitoring Amazon MQ is essential for ensuring reliable message delivery, preventing bottlenecks, and optimizing broker performance. Applications Manager's Amazon MQ monitoring tool provides real-time insights into broker performance, availability, and health, ensuring smooth message queueing and communication. With proactive alerts, anomaly detection, and performance optimization, the tool helps prevent downtime, enhance reliability, and maintain seamless message flow.

Monitored Parameters

Go to the Monitors Category View by clicking the Monitors tab. Click on the Amazon MQ Service instance available under Amazon in the Cloud Apps section. Displayed below is the Amazon MQ Service bulk configuration view distributed into three tabs:

  • Availability tab gives the availability history for the past 24 hours or 30 days.
  • Performance tab gives the health status and events for the past 24 hours or 30 days.
  • List view tab enables you to perform bulk admin configurations.

By clicking a monitor from the list, you'll be taken to the Amazon MQ Service dashboard which includes the following tabs:
