ADeploy a Fluent Bit daemonset on the GKE cluster to log data in Cloud Logging. Analyze the logs to get insights into your application code’s performance.
BCreate a custom dashboard in Cloud Monitoring to evaluate the CPU performance metrics of your application.
CConnect to your GKE nodes using SSH. Run the top command on the shell to extract the CPU utilization of your application.
✓DModify your Go application to capture profiling data. Analyze the CPU metrics of your application in flame graphs in Profiler.
