The AF server includes a Windows PerfMon counter called AF Health Check. Load balancers typically do not read this counter directly, but you can access the information it provides. This is the preferred method to check the availability of the AF application service and SQL Server. |

Allows you to monitor the AF server like a typical web server. See Monitor the AF Health Check counter for more information. |
