Managed Prometheus insights¶

Gustavo Pantuza, Rodrigo Moraes, and Samuel D’Aquino JR of VTEX together with my colleague José Augusto Ferronato wrote about how VTEX scales to 150 million metrics using Amazon Managed Service for Prometheus, sharing useful insights.

Trace-based testing Lambda¶

Oscar Reyes (Tracetest) on Testing AWS Lambda & Serverless with OpenTelemetry, showing in a hands-on manner how to set up and run trace-based tests for a AWS Lambda Function.

Prometheus commits to OTel¶

I was very happy to find Our commitment to OpenTelemetry on the Prometheus blog. Learn from Goutham Veeramachaneni and Carrie Edwards what is planned for 2024, from GAing OTLP ingestion to native support for OTel resource attributes. Exciting times!

SQS context propagation¶

Marcin Sodkiewicz, observability expert at Ryanair, wrote about AWS & OpenTelemetry: SQS context propagation where he provides a deep dive on the instrumentation of async communication, focusing on SQS this time (more to come in this series). Thanks a lot for sharing!

Frame pointers¶

The one and only Brendan Gregg, outstanding performance engineer and Flame Graph inventor, published The Return of the Frame Pointers on his blog. He provides some historical context and future directions on this interesting topic, which, amongst other domains, is super relevant for the continuous profiling space.
