What Do I Do If a Lot of Access Logs Are Generated During Health Checks?
- You can increase the health check interval as follows:
Log in to the management console.
Locate the load balancer and click its name.
On the Backend Server Groups tab page, locate the backend server group.
In the Basic Information area, click Configure next to Health Check.
Change the health check interval to a larger value.
Risk: After the health check interval is prolonged, the time for the load balancer to detect unhealthy servers will increase.
- You can disable the health check function as follows:
Log in to the management console.
Locate the load balancer and click its name.
On the Backend Server Groups tab page, locate the backend server group.
In the Basic Information area, click Configure next to Health Check.
Disable the health check.
Risk: After health checks are disabled, the load balancer will not check the backend servers. If a backend server becomes faulty, the load balancer will still route requests to this server.
