About the observability stack (tobs) for Kubernetes

The observability stack (tobs) for Kubernetes is a tool that aims to make it simpler to install a full observability stack into a Kubernetes cluster. Currently this stack includes:

• Kube-Prometheus the Kubernetes monitoring stack
  • Prometheus to collect metrics
  • AlertManager to trigger the alerts
  • Grafana for visualization
  • Node-Exporter to export metrics from the nodes
  • Kube-State-Metrics to get metrics from Kubernetes API server
  • Prometheus-Operator to manage the life-cycle of Prometheus and AlertManager custom resource definitions (CRDs)
• Promscale (design doc) to store metrics for the long-term and allow analysis with both PromQL and SQL
• TimescaleDB for long term storage of metrics and provides ability to query metrics data using SQL
• Promlens tool to build and analyse promql queries with ease
• Opentelemetry-Operator to manage the lifecycle of
  OpenTelemetryCollector Custom Resource Definition (CRDs)
• Jaeger Query to visualize the traces

You can also use the tobs Helm chart directly, or as sub-charts for other projects.
