Diagnosing Load Balancer Issues Using Smart Check
Use Smart Check to diagnose and fix a load balancer's configuration and environment issues.
Your load balancer includes Smart Check, which runs in the background to detect issues with the load balancer configuration and operating environment. Access the results of Smart Check activities through the Oracle Cloud Infrastructure Console as a resource of the load balancer.
Smart Check evaluates the load balancer approximately every 10 seconds. Each check reviews configuration issues such as the following:
-
Load balancer's backend servers are in a drain or offline state.
-
Protocol mismatches exist on the HTTP listener.
-
Port mismatches exist on the HTTP backend servers.
Smart Check results are presented in tabular format within the load balancer's Details page. Each category of issues has an assigned status of High, Medium, Low, and OK. You can display details of each check, including recommendations for corrective actions where necessary. An Informational tab is also available to provide best practices and recommendations on how to make your load balancer work optimally.
