Custom Metrics Stackdriver Adapter
The Custom Metrics Stackdriver Adapter is a Kubernetes component that enables the collection and export of custom application metrics from pods to Google Cloud's Stackdriver (now part of Google Cloud Operations). It works by reading metrics from pods via the Prometheus exposition format or other sources, converting them, and pushing them to Stackdriver for monitoring and alerting. This tool is essential for integrating custom Kubernetes application metrics with Google Cloud's monitoring ecosystem.
Developers should use this adapter when running Kubernetes workloads on Google Kubernetes Engine (GKE) or other platforms that need to send custom metrics to Stackdriver for centralized monitoring. It is particularly useful for applications that expose metrics in Prometheus format but require integration with Google Cloud's tools for dashboards, alerts, and analysis. Use cases include monitoring business-specific metrics like user sign-ups, API latency, or custom resource usage in cloud-native environments.
