newrelic.com ↗Vendor-agnostic telemetry collection
The OpenTelemetry Collector is the great equalizer of observability — a vendor-neutral pipeline that collects logs, metrics, and traces from your apps and routes them anywhere. Prometheus, Jaeger, Datadog, Grafana Cloud — send the same telemetry to multiple backends simultaneously.
Distributed tracing system
Zipkin pioneered distributed tracing — it's the tool Twitter built to understand how requests flow through microservices. Send spans from your services, and Zipkin gives you a visual trace showing exactly where latency lives.
Time-series database as a Postgres extension
TimescaleDB is time-series data without leaving Postgres. It's an extension, not a separate database, which means your existing SQL knowledge, tools, and ORMs all just work.
APM and monitoring system
SkyWalking is a full-stack APM platform — distributed tracing, metrics aggregation, service topology maps, and alerting in one Apache project. It auto-instruments Java, .NET, Node.js, Go, Python, and Rust services without code changes, then visualizes the entire call chain across your microservices.
