loadBalancers
Load Balancer Monitoring Design Load balancer (Internal and external ) in Azure distribute traffic to the backend applications and hence when it comes to monitoring there are multiple use cases for monitoring. Usually, the intent of monitoring is either to monitor application or the availability of the load balancer. Load balancers are exposed internally & externally and therefore data path availability is another dimension which may require monitoring. Telemetry from session analysis, response time analysis and connectivity analysis aid in analyzing root cause of performance issues of a load balancer and underlying application.
We could look in detail into SNAT port exhausting or port already in used when load balancer is not responding or accepting new connection to see and understand the pattern of traffic. Overall, Load balancer telemetry can group for performance analysis and availability analysis. Performance analysis can be further narrowed down to analyzing slow response or unavailability of load balancer or underlying application.
Availability is broken down to load balancer availability & data path availability as well as availability of underlying application.
The following diagram explains the most common scenarios and use cases for load balancer monitoring.
