Grafana Mimir is an open-source, horizontally scalable long-term storage backend for Prometheus metrics at massive scale.

Grafana Tempo is an open-source distributed tracing backend that stores traces in object storage, requiring only a trace ID for retrieval.

eBPF is a Linux kernel technology that allows programs to run safely in kernel space, enabling deep observability and security without code changes.

The four golden signals are latency, traffic, errors, and saturation — the key metrics every production service should monitor.

The RED method monitors three key metrics for request-driven services: Rate, Errors, and Duration.

The USE method monitors infrastructure resources by tracking Utilization, Saturation, and Errors for every resource.

The sidecar pattern deploys a helper container alongside the main application container in a pod, extending functionality without code changes.

An observability pipeline collects, transforms, routes, and filters telemetry data between sources and destinations for cost optimization.

Linkerd is a lightweight, CNCF-graduated service mesh for Kubernetes providing observability, security, and reliability with minimal complexity.

Jenkins is an open-source automation server that automates building, testing, and deploying software through CI/CD pipelines.
