Dual-exporting .NET metrics with OTLP and Prometheus.

The latest OTel Prometheus exporter for .NET lets you export your metrics to both systems in parallel, and migrate without a single cut-over event.

Dual-exporting .NET metrics with OTLP and Prometheus
Many applications export their metrics directly to Prometheus. If you’re unfamiliar with Prometheus, in a nutshell it’s a time-series database for storing metrics, like counters and histograms.…

Help us stabilize environment variable context propagation.

The OTel Specification now has a release candidate for environment variables as context propagation carriers. We want feedback before we mark it Stable.

Metrics, logs & traces tell you how systems behave. Entity events tell you what exists: a live bi-temporal graph of your infrastructure, with relationships now in the spec. This blog walks through building a consumer, from event-sourced storage to a queryable graph: buff.ly/QBrp1SC
What can you do with OpenTelemetry entity events?
Metrics, logs, and traces tell you how your systems behave. They are much quieter about what actually exists: which hosts, interfaces, switches, services, and volumes are out there right now, and,…

High-cardinality metrics can quietly become a memory problem. What should an SDK do when metric attribute combinations keep growing? This blog post explains the tradeoffs behind cardinality limits and how the SDK handles overflow while keeping memory bounded.

Metric cardinality limits in OpenTelemetry: a practical guide
OpenTelemetry metrics are designed to be safe to use in production. One part of that safety is the cardinality limit in the metrics SDK. The limit protects your process from unbounded memory growth…
