Beyond Root Cause Analysis for K8s: What Your Logs Should Be Telling You - Ronit Belson, Sawmills

Tuesday April 1, 2025 10:45 - 11:10 BST

Observability Day, Managing the Ever-increasing Volume of Observability Data

Logs are a goldmine of information, which is why they have become the backbone of business-critical monitoring and observability systems. Yet like gold, mining this value requires significant effort – sifting through endless entries is time-consuming, tiring, and costly. To reduce operational overhead and minimize mean time to resolution (MTTR), this talk explores advanced techniques for log summarization, offering methods to reduce log volume without losing critical insights for modern cloud-native and K8s environments.

We'll discuss the use of key attributes and metrics to make logs more meaningful and enable more rapid root cause analysis (RCA). The presentation will demonstrate semantic log understanding using advanced AI and contextual log analysis powered by large language models (LLMs) to automatically extract actionable insights and understand the deeper context of system behaviors and application flows.

From Logs To Insights: Real-time Conversational Troubleshooting for Kubernetes With GenAI - Tiago Reichert & Lucas Duarte, AWS

Tuesday April 1, 2025 11:20 - 11:45 BST

Observability Day, Managing the Ever-increasing Volume of Observability Data

In today’s distributed microservices landscape, Kubernetes environments generate vast volumes of logs, making troubleshooting complex and time-consuming. Operators often sift through massive data to identify issues, leading to prolonged downtime—a challenge that intensifies with multiple clusters. Discover how GenAI optimizes troubleshooting by transforming traditional logs into conversational insights. This session covers building an AI-driven observability solution with Large Language Models (LLMs). We start by configuring Fluent Bit collectors to gather systemd logs, Kubernetes events, and application logs, which are then streamed to a scalable object storage. By constructing a vector database, we enable users to query and interact with logs in natural language. We will provide a step-by-step guide that equips attendees with actionable knowledge to implement GenAI observability in their Kubernetes clusters.

From Chaos To Clarity: Scaling Observability at Dropbox With Centralized Logging Solution - Alok Ranjan, Dropbox Inc

Tuesday April 1, 2025 14:05 - 14:30 BST

Observability Day, End-user Talks about Observability Implementations

At Dropbox, managing observability for systems producing terabytes of logs daily posed a unique challenge. Initially, developers accessed logs by logging into individual servers, a process further complicated when we moved to containers. Containers are short-lived, which caused logs to disappear on termination. This highlighted the need for a scalable, persisted, centralized solution using open-source tools.

In this session, I’ll discuss our journey to build a robust observability framework centered on Loki as our logging solution. Scaling Loki to Dropbox’s data volume required extensive optimizations for reliable, efficient query performance. I’ll cover our deployment, challenges, and strategies for achieving high-performance logging.

We also integrated Grafana to unify logs and metrics in a single view, enhancing troubleshooting and security. Join us to learn how Dropbox scaled its observability with open-source solutions and key lessons from our experience.

Putting the Experience in UX: The Importance of Making Data Accessible - Adriana Villela, Dynatrace & Tim Banks, Caylent

Tuesday April 1, 2025 14:05 - 14:30 BST

Observability Day, Interesting Use Cases for Observability

Every organization, regardless of what they do, collects and relies on data. Our focus on Observability has largely been relegated to software engineering, operations, and other IT-focused roles. As such, data needs for sales, marketing, finance, HR, support, and other roles and groups are often overlooked or feel inaccessible to them. It only takes a good experience with something to change your relationship with it.

In this talk, Adriana and Tim will use real-life experiences and everyday examples to show how giving people a good experience with something with which they are unfamiliar can ignite a curiosity and appreciation. They will also explain why giving these experiences to everyone who collects and utilizes data can allow them to leverage it in new ways, unlocking new insights, new innovations, new approaches to everything they do.

Transmissions From the Tweet Factory: How Observability Transformed Mobile Performance at Twitter - Hanson Ho, Embrace

Tuesday April 1, 2025 14:40 - 15:05 BST

Observability Day, Observability Success Stories and Misfortunes

Twitter realized a decade ago that the biggest performance issues impeding usage occurred outside its data centers. But observability, taken for granted by backend devs and SREs, didn’t exist meaningfully on Android and iOS. Issues that don’t show up in profilers or end in crashes were practically invisible.

Stone by stone, the team built tooling that performantly and judiciously extracted telemetry on the client side. Using this newly discovered treasure trove of failure points and bottlenecks, performance was greatly improved – and in a verifiable way that shows how it can directly impact company KPIs like user growth and revenue.

Hanson Ho was there in 2015. For 7+ years, he helped build observability into the Android app and org. Listen as he describes how observability changed mobile at Twitter: what was recorded, how it was used, what results were achieved – and how the lessons learned can be applied by anyone that operates mobile apps, both in the tech and in the org.

The Art and Craft of No-touch Instrumentation - Michele Mancioppi, Dash0

Tuesday April 1, 2025 15:20 - 15:45 BST

Observability Day, Monitoring Dynamic Microservices and Containers in Real-time

OpenTelemetry automatic instrumentations greatly help with achieving a high baseline of observability for applications. But applying them in containerised environments still requires manual, error-prone intervention by users. LD_PRELOAD-based injection is an advanced technique that has been used by commercial vendors for a decade or more, is by now very well understood, and does not require access to the Kernel like eBPF does (which is a huge challenge in managed compute environments), or any increase in permissions other than what the host runtime has.

In containerized environments, one key challenge of pushing observability data is to identify the sender, to allow data enrichment, i.e. attaching attributes, tags, metadata based on container or Pod metadata.
This problem has been commonly solved by asking the sender to provide its own container id, easily available through /proc/self/cgroup.

When Datadog started evaluating cgroupv2, it quickly became apparent that this approach was not usable anymore, prompting us to find new solutions as the most common workaround (using mountinfo) is actually not reliable.
In this talk we'll explain why the container id is not available anymore (due private cgroup namespace) and present two solutions that we worked on.

We will go through the benefits of each one and will share how these solutions could be used in other observability projects, like OpenTelemetry.

⚡ Lightning Talk: From HAR To OpenTelemetry Trace: Redefining Your Observability - Antonio Jimenez Martinez, Cisco ThousandEyes

Tuesday April 1, 2025 17:15 - 17:25 BST

Observability Day, Interesting Use Cases for Observability

Have you heard about HTTP Archive (HAR) files and wondered how you could leverage this data for deeper insights into your web applications?

Imagine analyzing your page load request data as OpenTelemetry traces in your favorite observability backend. In this talk, we will explore the lessons learned from transforming HAR into an OpenTelemetry trace and streaming it to Jaeger.

You'll gain insights into the process of converting HAR data into spans following OpenTelemetry semantic conventions, and learn about the architecture we used to send these traces to any observability backend via the OpenTelemetry collector. This session is perfect for developers and observability engineers looking to enrich their tracing capabilities with detailed HTTP request data.
