This package adds a Health Check to report on the configuration information used in sucessfully setting up Flexible Load Balancing in Umbraco v7.8+ - This is particularly useful in the context of troubleshooting Flexible Load Balancing issues.
The Health Check will display the value of the UmbracoApplicationUrl, and importantly how this has been determined by Umbraco. If the UmbracoApplicationUrl has been manually set that it follows the correct pattern and can be 'requested' by the server. It will check and display the values of some key Load Balancing configuration settings, eg Distributed Calls, ElectionDisabledForSingleServer, LocalTempStorage. Finally it will display the Current Server Role, Identity and if DatabaseRegistraar is in use a list of the active servers in the Flexible Load Balancing Pool.
Install the package, and visit the Health Check tab of the developer section to run the 'Load Balancing Configuration' Health Check.
This package currently only runs on the V7 series of Umbraco.
