OTel transform processor¶
Read Mastering the OpenTelemetry Transform Processor by Ayooluwa Isaiah to learn what this important processor is and how to use it.
OTel in prod¶
The good folks from Sematext published another two great hands-on resources that help you using OTel in production:
- OpenTelemetry Production Monitoring: What Breaks, and How to Prevent It
- Running OpenTelemetry at Scale: Architecture Patterns for 100s of Services
Telemetry Drops¶
If you have not yet come across Telemetry Drops then I strongly recommend to check it out: keep up to date with what's going on via the amazing podcast, delivering a weekly OpenTelemetry digest. And, if you are preparing for the OpenTelemetry Certified Associate (OTCA) exam, go and take the OTCA Practice Exam.
Metrics from logs¶
Adam Gardner published Transform your logs to metrics (and do maths with metrics) using the OpenTelemetry Collector, check out the 11 min video for details.
Managed metrics pipeline¶
A launch from last week by a peer AWS service team that makes me happy: Amazon OpenSearch Ingestion now supports Amazon Managed Service for Prometheus as a sink. Allows you to pre-process metrics before ingesting them into AMP.
That was it for this edition of the o11y newsletter. Feel free to share news items with me via Bluesky DM. Stay safe and hope to see you around next week!
