Azure Service Bus is a fully managed enterprise message broker that enables asynchronous messaging between distributed applications. It allows components to communicate reliably, securely, and at scale. With Datadog's Azure Service Bus integration, users can surface Service Bus metrics with the Azure integration, track free space and size of topics or queues, and set up monitors to send alerts when queues or topics begin to run out of space. The integration helps teams troubleshoot performance issues by providing visibility into message queues, topics, and subscriptions, and enables them to pinpoint failures, investigate root causes, and take proactive actions before they impact application performance. It also enables teams to stay ahead of customer issues by tracking queue backlogs, message failures, and throttling events in real time, and scale resources as needed. The integration provides deep visibility into cloud infrastructure, applications, security, and networking within the Azure ecosystem, allowing teams to collect real-time metrics, logs, and traces from services like Azure Virtual Machines, Kubernetes Service (AKS), Functions, and App Service.
