Skyscanner scales OTel¶
Another week, another awesome end-user story via the OTel blog: How Skyscanner scales OpenTelemetry: managing collectors across 24 production clusters by Johanna Öjeling, Juliano Costa, Tristan Sloughter, and Neil Fordyce.
Optimizing tail sampling¶
Zhu Jiekun shared VictoriaMetrics at KubeCon: Optimizing Tail Sampling in OpenTelemetry with Retroactive Sampling, thank you!
Monitoring applied¶
In Monitoring CPU and Memory on Your VPS with AppSignal Muhammed Ali reports on some useful monitoring applications.
OTel Gauge vs Histogram¶
From leboncoin tech: OpenTelemetry’s Gauge vs Histogram : Latency tracking done right, a really excellent deep dive.
Tooling¶
Tooling I stumbled upon and found interesting and/or helpful:
- OpenTelemetry SDK Versions, a skill for your fav GenAI environment.
- ASAPQuery, a drop-in query accelerator for queries in PromQL etc.
- Cardinality Guardian, a OTel processor addressing metric cardinality explosions.
- Otelite, a light-weight OTel receiver and dashboard for local development.
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!
