Alibaba Cloud Container Compute Service (ACS) provides the Ingress diagnostics feature to help you diagnose common Ingress issues. This topic describes the Ingress diagnostic items and provides suggestions on how to fix issues.
The diagnostic items of Ingress diagnostics include the Ingress, startup parameters, Ingress pod error log, and Ingress controller Server Load Balancer (SLB) instance.
When you use the diagnostics feature, ACS runs a data collection program on each node in the cluster and collects diagnostic results. The program collects the following information, the system version, loads, status of container components, and key error messages in system logs. ACS does not collect business information or sensitive data.
