Your company manages three distinct environments: production, staging, and development, each with its own GCP Project. Additionally, there's a monitoring project featuring two workspaces—one dedicated to production and the other shared between development and staging. A GKE Cluster is operational in both staging and development environments for testing an application before its production deployment. Both clusters host a service named 'app-serve', and an alerting policy monitors this service within the workspace. However, incidents on the service cannot be uniquely attributed to either the development or staging service in the GKE monitoring dashboard. What is the most efficient solution to this issue with minimal operational overhead?
