## When to use this site

Use Telemetry Drops to compare OpenTelemetry training for software engineers, SREs, and DevOps professionals; learn Collector configuration and telemetry engineering; find workshops; or prepare for the OpenTelemetry Certified Associate (OTCA) exam.

Read the linked public pages with GET requests. They contain the authoritative course curriculum, prices, availability, authors, and publication dates. Request Accept: text/markdown at a page's canonical URL for Markdown, or follow its alternate Markdown link. Use the sitemap for the complete page inventory and the RSS feed for recent articles.

## Courses

## Articles

- [Three OpenTelemetry talks worth watching from KubeCon India 2026](https://telemetrydrops.com/blog/best-otel-talks-kubecon-india-2026/): Our picks from KubeCon + CloudNativeCon India 2026: a Prometheus outage post-mortem, a deep dive into the hidden cost of telemetry format conversions, and how to instrument AI agents with OpenTelemetry.
- [OTLP support is not OpenTelemetry support](https://telemetrydrops.com/blog/otlp-is-not-otel-native/): Accepting OTLP only means a vendor opened a port and can decode the wire format. Being OpenTelemetry-native means preserving and understanding the data model: semantic conventions, a shared resource model, and version drift.
- [Weaver from zero to hero: a getting started guide](https://telemetrydrops.com/blog/weaver-from-zero-to-hero/): Adopt OpenTelemetry Weaver to turn hand-maintained telemetry constants into a versioned schema with generated code and CI-enforced contracts.
- [Six OpenTelemetry talks worth watching from KubeCon EU 2026](https://telemetrydrops.com/blog/best-otel-talks-kubecon-eu-2026/): Our picks from KubeCon EU 2026 in Amsterdam: three applied observability talks showing real-world OTel deployments, and three core project updates that affect every Collector operator.
- [Route your logs by severity with the OpenTelemetry Collector](https://telemetrydrops.com/blog/severity-based-log-routing/): How to use the OpenTelemetry Collector's routing connector to split logs by severity, sending critical logs to your vendor and archiving the rest to cheaper storage.
- [You don't have too much telemetry. You have bad telemetry.](https://telemetrydrops.com/blog/bad-telemetry-not-volume-problem/): Why observability cost problems are governance problems, not volume problems. A practical framework for identifying and eliminating telemetry waste before reaching for sampling.
