Applications Manager's Azure Load Balancer monitoring tool acts as the best solution to monitor the availability and performance of your Azure Load Balancer. With this monitoring tool, it is possible to gain complete visibility into your Load Balancer deployed on Azure. It tracks the key metrics such as Data path availability, Health probe status, Data throughput, SNAT connection, etc.
To learn how to create a new Azure Load Balancer 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 Load Balancer monitor from the displayed tooltip. This action will display the bulk configuration view for Azure Load Balancer in three tabs:
The Microsoft Azure monitor provides a brief detail of the Azure Load Balancer under the given subscription. Following are the list of metrics monitored in Azure Load Balancer Monitoring in their corresponding tabs:
