lb/Validate Backend Service Port Configuration
Product: Load balancing
Step Type: AUTOMATED STEP
Description
None
Success Reason
The load balancer is performing health checks on the same port used for serving traffic. This is the standard configuration.
Uncertain Reason
The load balancer is conducting health checks on port {hc_port} for the backend service {bs_resource}. However, this health check port differs from the port used by the load balancer for serving traffic on some backend instance groups. The backend service is configured to use the “{serving_port_name}” port, which is then translated to a specific port number based on the “{serving_port_name}” port mapping within each backend instance group.
Affected backends:
{formatted_igs}
This configuration can be problematic unless the load balancer has been configured to use a different port for health checks purposefully.
Uncertain Remediation
Verify that the health check port is correctly configured to match the port used by the application if the health check is intended to check the serving port.
