Overview of WAF Health Check Monitoring
WAF Monitoring allows you to continually test upstream servers to ensure they are healthy. If a server fails health checks, WAF avoids sending client requests to it. Once the server recovers and passes the required number of checks, it is gracefully added back into the server group.
Monitors can be applied at two levels:
- Server Group Level: The monitor is applied to all servers within the group automatically.
- Individual Server Level: A monitor attached to a specific server overrides the server-group monitor configuration.
