Sponsored Keynote: The Work Before the Magic: Autoremediation Readiness - Alok Bhide, Chronosphere | A Palo Alto Networks Company
Thursday May 21, 2026 9:25am - 9:30am CDT
The pitch for autoremediation is hard to resist: AI doesn't just surface issues faster — it fixes them on the spot, leaving you to kick back, validate, and observe. MTTR doesn't just shrink; it becomes a relic. Problems vanish before anyone even notices they existed.

But rush into it without solid data, proper curation, and clear policy, and you're pulling a tap with too much pressure — nothing but foam, no beer.

Closed-loop remediation isn't a shortcut. It's the payoff at the end of a disciplined, AI-driven observability practice.

In this talk, we'll walk through the three things that make autoremediation actually work:

  1. System coverage that holds up at real scale
  2. Data that's clean, navigable, and actionable
  3. Ground rules for what AI is — and isn't — allowed to do

You'll walk away with a practical readiness checklist and a clear framework for deciding where autoremediation belongs in your stack, and where it definitely doesn't.

No hype. Just the work that earns AI the right to act in production.

Keynote: 10 Million Spans Per Second: Lessons From Scaling OpenTelemetry at Reddit - Trevor Riles, Reddit
Thursday May 21, 2026 9:35am - 10:00am CDT
Reddit processes over 25 billion tracing events per hour across thousands of services. In this talk, we share how we scaled our OpenTelemetry-based distributed tracing platform by 67% in one year—and what broke along the way.

We'll cover our architecture: OpenTelemetry instrumentation across Python, Go, and JavaScript baseplate libraries feeding into Kafka pipelines and ClickHouse storage. You'll learn how we handled an incident that spiked ingestion to well over 10 million spans per second, the sampling strategies we developed to balance cost with debuggability, and why instrumenting three language runtimes simultaneously is harder than it sounds.

Key takeaways:
- Practical patterns for multi-language OTel instrumentation at scale
- Remote sampling strategies that adapt to traffic patterns
- ClickHouse schema design for sub-second trace queries
- Building adoption through cross-functional partnerships, not mandates

Whether you're starting your tracing journey or scaling an existing platform, this talk provides battle-tested lessons from running distributed tracing infrastructure serving one of the world's largest online communities.

The Invisible Tax: How Data Format Conversions Drive up Telemetry Pipeline Costs - Cijo Thomas & Joshua MacDonald, Microsoft
Thursday May 21, 2026 10:20am - 10:45am CDT
Telemetry signals traverse long pipelines before reaching observability backends. While enrichment, filtering, and redaction provide clear value, significant compute cost often comes from repeated conversion through different data formats.
Telemetry commonly flows through SDK formats, wire protocols, collector‑internal formats, and backend ingestion schemas. Each boundary introduces marshaling, unmarshalling and copying. These transformations add no new information, yet consume CPU and memory and scale linearly with volume—creating a hidden "transform tax" that compounds dramatically at terabyte scale.
This talk will share results from measuring instrumented OpenTelemetry SDK and Collector pipelines. We quantify compute spent on pure format conversion versus value‑generating processing and show how these costs grow with scale.
Attendees will learn about conversion costs and strategies to reduce waste: eliminating unnecessary translations, aligning pipeline representations, leveraging zero‑copy techniques, and minimizing transformation hops between pipeline stages. We also examine Apache Arrow‑based representations as one approach to reducing this overhead.

Taming Observability at Scale in a Multi-Cluster Kubernetes Platform at Bloomberg - Joe Nathan Abellard, Bloomberg
Thursday May 21, 2026 10:50am - 11:15am CDT
Bloomberg runs a managed, multi-cluster Kubernetes platform built atop Karmada to support AI and streaming analytics workloads. This comes with challenges around observability at scale. To meet disaster recovery requirements, we use a multi-region architecture where each Karmada control plane is hosted on management clusters spanning multiple regions. This helps ensure high availability, but also adds complexity related to observability. For example, how do we aggregate and visualize metrics across multiple Prometheus servers when each management cluster has a dedicated Prometheus setup?

This talk covers our multi-region architecture to meet DR requirements and our Prometheus stack with Thanos for global metrics aggregation. We’ll explore how we choose the right signals and define meaningful alerts in a complex multi-cluster environment to curb alert fatigue, while ensuring timely issue detection. We’ll also discuss the challenges of defining SLIs and SLOs in a multi-tenant platform.

Quantiles at Scale: Choosing the Right Estimation Algorithms for Observability - Mike Shi, ClickHouse
Thursday May 21, 2026 11:20am - 11:45am CDT
Quantiles like p90 and p99 sit at the heart of observability. They define dashboards, drive SLOs, and shape how teams reason about system performance. They are also some of the most expensive metrics to compute, and the cost grows fast as data volumes increase.
To keep up, observability systems rely heavily on approximate quantile algorithms such as sketches and probabilistic data structures, including t-digest. These approaches work well at small and medium scale, but at tens or hundreds of petabytes, things start to creak and limitations become apparent.
We share hard won lessons from operating ClickHouse at extreme scale, where quantile estimation must remain accurate and affordable over hundreds of petabytes of data. We break down the most common quantile algorithms used in observability today, explain their real trade offs, and show when each approach makes sense. We also explore a critical design decision: when quantiles should be computed on the fly at query time versus pre aggregated during ingestion.
The goal is to give you a practical framework for choosing quantile algorithms that scale, rather than blindly relying on defaults that stop working as your data grows.

⚡ Lightning Talk: Beyond Billions: Operating Thanos, Prometheus & OpenTelemetry at Trillion-Scale - Narendra Sanikommu, Nvidia
Thursday May 21, 2026 11:50am - 12:00pm CDT
Operating a metrics system beyond billions of data points introduces failure modes that don't exist at smaller deployments. This lightning talk shares battle-tested lessons from running, Thanos, Prometheus and OpenTelemetry in production across distributed Kubernetes environments, focusing on three critical challenges: implementing multi-tenancy without noisy neighbor problems, building rate limiting that prevents a single tenant from destabilizing the cluster, and isolating query workloads so expensive queries don't starve metric ingestion.

The talk walks through real incidents where these challenges caused production impact, including 5xx errors on Thanos Receivers from unbounded queries, Prometheus remote write lag and partial query results from overwhelmed Store Gateways. For each problem, the talk presents custom solutions developed—including tenant-aware rate limiting middleware and workload isolation patterns—and shares concrete configuration approaches that attendees can apply to their own deployments.
Attendees will leave with actionable techniques for scaling their observability infrastructure to trillion-scale while maintaining reliability under load.

Panel: Telemetry That Matters - Diana Todea, VictoriaMetrics; Antonio Jimenez Martinez, Cisco ThousandEyes; Laura Luttmer, Dynatrace
Thursday May 21, 2026 1:15pm - 1:50pm CDT
Instrumentation has never been easier, but are we truly gaining clarity? As data volumes rise, dashboards multiply, and observability costs increase, developers may feel less insight and more friction. Are we collecting telemetry with purpose or just because we can? What problem is this data meant to solve?
This panel brings together practitioners across open standards, developer experience and real-world reliability engineering. The discussion will examine how zero code instrumentation affects workflows and system understanding, how meaningful telemetry improves day to day engineering work and why unfiltered or unstructured data often has the opposite effect. The conversation will cover practical lessons for filtering, dropping, reducing and shaping telemetry so teams maintain visibility without unnecessary volume or cost. Finally, we explore scaling observability across fleets of collectors with an OpAMP server, ensuring consistent signal delivery and manageability as telemetry grows.
At the center is a guiding question: What is the purpose of the telemetry we collect and how do we ensure it remains aligned with developer needs, operational requirements, and system reliability?

Taming Tenancy, Cost and Architecture at Collibra Through OpenTelemetry and Our Telemetry Backbone - Alex Van Boxel, Collibra
Thursday May 21, 2026 1:55pm - 2:20pm CDT
Operating a SaaS platform presents the same observability problems as any other enterprise, but due to the scale and tenancy, we introduce a huge multiplier on the observability signals, having an effect on cost and effectiveness.

This session dives into the techniques Collibra used to tame these problems and how to maintain clarity when infrastructure spans virtual machines, modern Kubernetes clusters, and a complex mix of single- and multi-tenant architectures. Without the right context, telemetry data becomes a noisy, indistinguishable flood.

We will dive into the architectural decision to leverage the C4 system model, ensuring every piece of telemetry carries the vital context of what it belongs to and where it sits in the hierarchy. Enabling us to gain insights into both signal attribution and allowing virtual chargebacks. The presentation details the implementation of a pipeline using custom-built OpenTelemetry collectors designed to handle the data and enrich it before sending it to the appropriate backends.

This session will give you practical insights on the challenges SaaS platforms have, but the techniques that are used to tame them can be applied everywhere.

The Speed of Metrics, the Fidelity of Traces: Architecting Post-Collection Aggregation - Zack Owens, New Relic
Thursday May 21, 2026 2:25pm - 2:50pm CDT
As organizations adopt observability practices, they face a scalability paradox: systems now generate petabytes of traces and logs, but querying this raw telemetry over long time horizons becomes prohibitively slow and expensive due to the data volume.

The standard solution of pre-aggregating high-cardinality telemetry into metrics at collection time through features in the OpenTelemetry collector works well for known patterns but fails when engineers need to ask new questions about historical data. This creates an uncomfortable choice for engineers and operators: fast dashboards with pre-aggregated metrics, or high-fidelity traces and logs that become unusable beyond short time windows.

This talk presents a post-collection aggregation approach that enables fast queries over long time periods of detailed telemetry without changes to collector-side configuration. This session explores techniques for incremental view materialization that work with timeseries data. Attendees will leave with concrete architectural patterns which are applicable to open source databases like ClickHouse or OpenSearch to answer novel questions without sacrificing query speed or data fidelity.

When the Cloud Fails: Debugging the "Undocumented" - Dhruv Jain, Gojek (GoTo Group) Indonesia
Thursday May 21, 2026 2:55pm - 3:20pm CDT
What happens when a system degrades under high load while all internal metrics remain “green”? At hyperscale, supporting on-demand services across Southeast Asia’s most populous countries, a team observed up to a 7% drop in message delivery. The root cause was not application code, messaging brokers, or load balancers, but a hidden limitation deep within a cloud provider’s firewall.

This war-story session presents a forensic investigation into a managed cloud load balancer and its interaction with connection-tracking tables. The talk walks through the production cutover that triggered the issue and the targeted load testing that ultimately isolated the failure to cloud infrastructure behavior invisible to standard monitoring.

Beyond root cause analysis, the session focuses on outcomes: how sustained, evidence-based debugging led the cloud provider to acknowledge the issue—initially labeled a “limitation”—and introduce a new observability metric, firewall/connections_tracked. Attendees will leave with a practical framework for debugging black-box cloud failures and identifying the node-level metrics needed to detect silent network drops before they impact users.

The Full Picture: Visualizing Service "Fullness" To Rethink Saturation Prevention - Tal Nordan, Independent
Thursday May 21, 2026 3:40pm - 4:05pm CDT
Saturation has long been the stepchild of "the Four Golden Signals of SRE". While latency, traffic, and errors are directly measurable through metrics like P99, RPS, and 5xx rates, monitoring just how "full" a service is relies on indirect symptoms such as CPU usage or queue depth. Yet, saturation should ideally rather be the first signal to alert, as once it's reached, other signals - latency and errors - spike fast.

The inability to directly observe and mitigate saturation drives excessive safety margins, chronically low CPU utilization and massive compute waste in latency-sensitive and customer-facing systems. This session introduces an open-source approach extending Envoy proxy and its seamless integration through eBPF and Cilium, to provide direct observability into service saturation, by comparing each instance's live number of concurrent requests to its true concurrency limit. We then explore how such direct visualization of saturation can help reduce MTTR and minimize waste.

Secure by Design: Rethinking Test Credentials for Synthetic Monitoring - Katie Kodes, Katie Kodes
Thursday May 21, 2026 4:10pm - 4:35pm CDT
Synthetic monitoring and end-to-end testing often require dangerous levels of access to production systems. Last summer, I nearly emailed my bank details to a team I was training on new testing tools. If I hadn't caught that mistake, I probably would have dumped them into an OTel collector too.

This session explores the security implications of common testing practices, and presents practical alternatives that maintain observability without compromising security.

Attendees will learn authentication and authorization patterns to improve test security across the software development lifecycle.

Implementing mitigations like health check endpoints, synthetic data, and privilege separation spans the full stack of infrastructure, development, monitoring, and governance. Attendees will leave with a shared vocabulary they can use to align business, development, security, and observability teams on safer test traffic in production.
