Navigating the Open Source Observability Landscape
summary
OpenTelemetry becomes the vendor‑neutral OpenTelemetry GA framework covering traces, metrics and logs with an OTLP gRPC protocol, language SDKs, a collector for receivers/processors/exporters and no built‑in backend; Prometheus remains the metric engine now pushing Prometheus 3.0 beta with tighter OpenTelemetry metric storage goals but still a single‑node design often paired with Thanos/Cortex for scale; Jaeger publishes Jager V2 RC1 reusing the OTEL collector; OpenSearch (a fork of Elasticsearch) reports ~700M downloads, 75 partners and joins the Linux Foundation. profiling and eBPF signal expansion appears across projects.
