| Welcome + Opening Remarks | Bartłomiej Płotka | 08m |
Co‑located with KubeCon and started last year in Detroit this event structures the day around concrete tooling and user stories: schedule lists project… | ||
| Prometheus Project Updates | Richard Hartmann | 03m |
Prometheus now accepts out-of-order sample ingestion, removes the need to reorder time series at scrape time, and adds native histograms with an… | ||
| Open Telemetry Project Updates | Austin Parker | 04m |
Project updates cover concrete progress: metrics API and SDK stabilized with initial releases for Java, Go and Python and native histogram support shipping in… | ||
| Fluentd and Fluent Bit Project Updates | Eduardo Silva | 05m |
Fluent Bit 2.1 arrives as a major release with hot reload for live config updates, a logs-to-metrics converter to expose log-derived Prometheus metrics, and… | ||
| Telemetry Pipelines: Your Recipe for Success | Anurag Gupta | 05m |
Argues that separating lightweight collectors from a central processing tier reduces ingestion costs, shortens MTTR, and avoids fleet-wide misconfigurations… | ||
| Prometheus Native Histograms in Production | Björn Rabenstein | 21m |
Native Prometheus histograms run behind a feature flag and keep one series per histogram instead of many bucket series, cutting series from ~16,000 to 964 in… | ||
| Does It Add Up? Exploring the Delta Temporality in OpenTelemetry & Beyond | Matej Gera, Oded David | 23m |
Explains when delta versus cumulative temporality actually matters, shows how OpenTelemetry uses start_time_unix_nano plus timestamp to form unbroken… | ||
| Using OpenTelemetry’s Exponential Histograms in Prometheus | Ruslan Kovalov, Ganesh Vernekar | 26m |
Explains how OpenTelemetry’s dense representation exponential histograms map to Prometheus’s sparse representation native histograms, with concrete encoding… | ||
| AI and Observability Role in an E-Government Ecosystem | Zoltan Mathe | 19m |
E‑government platform serving 5M users and 4M eIDs and handling 60 million requests per month runs hundreds of heterogeneous services (on‑prem plus Kubernetes… | ||
| Ingesting 6.5 Tb of Telemetry Data Daily Through Open Telemetry Protocol and Collectors | Gustavo Pantuza | 27m |
Architecture ingesting 6.5 TB/day of telemetry using OTLP and custom OpenTelemetry Collector binaries built with Collector Builder, exporting logs to AWS… | ||
| Panel Discussion: The Present and Future of Open Source Observability | Alex Boten, Lili Cosic, Juraci Paixão Kröhling, Anthony Mirabella, Alolita Sharma | 36m |
Panelists say collection is mostly solved for traces, metrics and logs while the next work is getting instrumentation into libraries and frameworks, and adding… | ||
| Observability at Scale: How Open Systems Collects Telemetry from Over 10'000 Edge Devices Worldwide | Joel Verezhak | 24m |
Open Systems monitors a fleet of over 10,000 edge devices and central clusters, ingesting roughly 110 million metrics (bursting to 240M) and the uploader… | ||
| Profiling Formats and Why You Should Care | Frederic Branczyk | 31m |
Compares folded stacks, pprof and Speedscope with concrete trade-offs: pprof deduplicates strings and supports synchronous symbolization, Speedscope adds… | ||
| Banking Observability at Scale | Arijan Luiken, Salvatore Vitale | 24m |
Productized open-source into a banking-grade Monitoring Data Pipeline (MDPL) that runs thousands of tenants by sharding Prometheus and Grafana on Kubernetes… | ||
| Closing Remarks | Bartłomiej Płotka | 03m |
Thanks and logistics plus ways to keep contributing: CNCF groups run ongoing meetings — Kubernetes SIG Instrumentation and TAC Observability — that meet… | ||
| eBPF for Observability: The Good, the Bad, and the Ugly | Anna Kapuścińska | 31m |
eBPF makes the Linux kernel programmable so observability runs without app code changes and with low overhead. Examples show kprobes and uprobes attached to… | ||
| Scaling Observability Stack for AIOPS | Ravi Hari | 15m |
Intuit runs ~2,500 Kubernetes services and keeps Prometheus metrics for a week by adding Thanos components (query, store, query-frontend) with S3 long‑term… | ||
