Microsoft Azure Event Hubs is a big data streaming platform and event ingestion service that can receive and process millions of events per second. It is part of the Azure Big Data ecosystem and is designed to handle real-time event streaming and telemetry ingestion scenarios.
An Azure Event Hub Cluster monitoring tool / Azure Event Hub Namespace monitoring tool is crucial to experience the platform at it's highest potential. Use Applications Manager to maintain your event streaming infrastructure's health, performance, and reliability.
To learn how to create a new Microsoft Azure Event Hub Cluster/Azure Event Hub Namespace monitor, click here.
Navigate to the Category View by clicking the Monitors tab. Hover over 'Child Monitors' under Microsoft Azure in the Cloud Apps table, and then select the Event Hub Clusters (or) Event Hub Namespaces monitor from the displayed tooltip. This action will display the bulk configuration view for Azure Event Hub Cluster/Azure Event Hub Namespace in three tabs:
