Stop ECS Containers From Collapsing Into One Service in OpenTelemetry

May 2, 2026 By Prathamesh Sonpatki In Last9
Why ECS containers collapse under service.name = aws_ecs and how to fix it for both EC2 launch type and Fargate, including the resource-vs-log-record pitfall that quietly breaks log filtering.

Telemetry Talks ep 4: Retroactive sampling and OpenTelemetry

May 1, 2026 By VictoriaMetrics In VictoriaMetrics
This episode of Telemetry Talks explores the evolution of an OTLP/gRPC tracing pipeline for VictoriaTraces within OpenTelemetry and VictoriaMetrics, including a shift from standard gRPC-Go to a simplified HTTP/2-based implementation to reduce complexity and improve flexibility. Together with the our guest, Jiekun, we revisited the VictoriaMetrics KubeCon talk ideas on tail-based and retroactive sampling — and their impact on the broader OpenTelemetry community.

How to Test SQS Workflows Locally with LocalStack and OpenTelemetry

Apr 30, 2026 By Prathamesh Sonpatki In Last9
LocalStack lets you run SQS, Lambda, and S3 locally in Docker — but there's a hidden trap: OpenTelemetry's default AWS propagator doesn't work with free LocalStack. Here's how to set up end-to-end local testing with working trace propagation.

End-to-End Trace Propagation Across SQS and Lambda with OpenTelemetry

Apr 29, 2026 By Prathamesh Sonpatki In Last9
SQS doesn't propagate trace context automatically. You instrument both sides, deploy, and get two disconnected traces. This post shows how to wire them into one waterfall — and the ESM format gotcha that silently breaks it every time.

How to Exclude Health Check Endpoints from Python OTel Traces

Apr 28, 2026 By Prathamesh Sonpatki In Last9
Health check endpoints generate thousands of identical, useless spans per day. Here are two production-ready approaches to filter them from your Python OTel traces — and the correctness trap most implementations miss.

Apr 24, 2026 By Prathamesh Sonpatki In Last9

Managing OpenTelemetry Semantic Convention Migrations With the Collector

Apr 23, 2026 By Mike Goldsmith In Honeycomb
Real production data tells the story better than I can. Juraci Paixão Kröhling, a friend and fellow observability practitioner at OllyGarden, recently shared an example from an anonymized production environment: 1,830 occurrences of http.url and 23,984 occurrences of url.full in the same dataset. Both attributes describe the same thing. Both are actively being written to the same backend at the same time.
