From Alert Notification to Comparison of Good and Bad Requests in One Click - Shreyas Srivatsan, Chronosphere

Metrics are a great tool for notifying when something goes wrong. Distributed tracing provides the ability to drill down deeper into an issue when triaging an alert with a non-obvious root cause. It’s already difficult to jump from metrics raising an alert to a representative problematic trace, but even once there, users often want to compare a problematic trace with a non-problematic one to help root cause the issue. This talk demonstrates how to jump straight from an alert notification to displaying a problematic trace along with a comparison to a non-problematic trace.

This is accomplished with a combination of open source tools such as Prometheus, Jaeger, Grafana and M3. The audience will learn how recent advances in the community can enable them to reduce their time-to-mitigation by providing the relevant context of a bad request vs a good request directly from a graph.

Tracing is For Everyone: Tracing User Events with GraphQL and OpenTelemetry - Nina Stawski, Splunk

There's been a lot of talk about the importance of observability and tracing for microservice-based applications. The use cases involved are focused on backend engineers and DevOps. But what about us front-end engineers? Often, we get blamed first when something breaks and the lack of consistent observability tools makes it difficult to debug issues.

With the emergence of OpenTelemetry for JavaScript, more front-end developers are looking to instrument their code and connect their traces with the backend. A growing number of teams are adopting GraphQL as their interface between UI and backend as well. This talk will illustrate the process of setting up your app for tracing with OpenTelemetry, show what’s common in GraphQL instrumentation compared to other libraries and describe the potential pitfalls of the approach. Building on that, we will discuss how tracing affects user experience.

Observability at Scale: Running OpenTelemetry Across an Enterprise - Jonah Back & Kranti Vikram, Intuit

Observability has been a huge topic of interest in the software industry over the last few years. One of the major components in observability is distributed tracing. Tools like Jaeger, Zipkin, OpenCensus, and OpenTelemetry have made it really easy to get started. Less easy, however, is getting your tracing infrastructure to a place where it can be fully leveraged across hundreds, if not thousands, of services.

This talk will cover Intuit's experience deploying tracing infrastructure using Kubernetes, Jaeger, and OpenTelemetry. It will cover a few key areas in Intuit's journey to running a highly available, multi-region tracing solution.

1) Scaling ElasticSearch to support 500M+ traces per day.
2) Secure, automated on-boarding of OpenTelemetry agents to central collectors
3) Leveraging open-source libraries to provide high quality trace data, enhanced with domain-specific attributes

Turn It Up to a Million: Ingesting Millions of Metrics with Thanos Receive - Lucas Servén Marín, Red Hat

Thanos is an open-source CNCF Sandbox project that builds upon Prometheus components to create a global-scale and highly available monitoring system. In this talk, Lucas Servén presents a solution for creating a multi-tenant horizontally scalable metrics ingestion system using the newest addition to the Thanos toolset: the Thanos Receive component. The talk considers the motivations for building a system capable of ingesting metrics from thousands of clusters, including: multi-cluster monitoring and cluster telemetry. Lucas discusses how Thanos Receive is able to satisfy these requirements and how its hash ring design allows it to scale and maintain ingestion availability even during upgrades. Finally, the talk demonstrates the practice of running an automatically scalable hash ring by leveraging the Thanos Receive Controller, Horizontal Pod Autoscaler, and the Prometheus Adapter.

Hubble - eBPF Based Observability for Kubernetes - Sebastian Wicki, Isovalent

Troubleshooting network issues in Kubernetes often requires deep insight into different layers of your stack. Hubble is a new open-source observability platform that aims to assist you in understanding what is going on in all layers of your Kubernetes network. Based on the Cilium CNI and the Linux kernel eBPF technology, it is able to obtain fine-grained visibility into network traffic and applications behavior, with low overhead and without having to modify applications.

In this talk, you will get a introduction into Hubble, and the technologies that power it, the Cilium CNI and eBPF. You will be presented with practical examples of how Hubble can be used to interactively troubleshoot complex network issues. The talk will show how to write custom Hubble metrics which allow you to benefit from eBPF's superpowers without having to write or understand any kernel code.

Speakers

Sebastian Wicki

Software Engineer, Isovalent

Sebastian Wicki is a software engineer currently working on Hubble and Cilium at Isovalent. Previously he worked on distributed stream processing systems for real-time data center network monitoring and analytics at ETH Zurich.

Monitoring GPUs at Scale for AI/ML and HPC Clusters - Bharti L Agrawal, NVIDIA

At Nvidia we have several large GPU K8s clusters for running deep learning training (AI/ML) workloads. On these clusters we need monitoring to support a range of user personas . First we have the end users (AI/ML researchers) who want to get an insight into how well their workloads used the GPUs and the system. Then we have the operations team who would like to monitor the general health of the cluster and be alerted in real time to any issues. Finally we have the stakeholders who would like to see the GPU utilization and saturation over time for capacity planning. These requirements cannot be satisfied by a standard “out of the box” setup.

In this presentation we will show how we used a combination of open source tools to address our requirements. We will discuss various deployment, maintenance, security and scale challenges we hit and how we resolved them for monitoring GPU data.

Make Prometheus Use Less Memory and Restart Faster - Ganesh Vernekar, Grafana Labs

These days, the most common reason for a Prometheus server to run out of memory is an excessive amount of time series in the so called head block, the part of the internal TSDB with the freshest data, which has to be kept in memory prior to consolidation into a block on disk. A large head block leads to a long restart time because the head block has to be rebuilt from the write-ahead log. On large servers, the restart time can be 10 minutes or more. Since restarts happen regularly to upgrade the binary or to change flags, the resulting interruption of sample collection is problematic. Even worse: After an OOM crash, the same replaying from the WAL has to happen, often causing another OOM crash immediately. Ganesh Vernekar will talk about the work started in late 2019 to persist parts of the head block earlier, thereby reducing both the memory footprint and the restart time.

Speakers

Senior Software Engineer, Grafana Labs

Ganesh has been contributing to Prometheus for over 5 years and is a Prometheus team member and maintainer of its Time Series Database (TSDB). Most recently, he worked on the new native histograms in Prometheus. He has also contributed to Cortex, Grafana Mimir, and Grafana.

Stateless Fluentd with Kafka - Steven McDonald, Usabilla

Fluentd is typically deployed as a central aggregator to which everything sends its logs for processing and routing. This superficially simple approach was found to be inadequate at Usabilla. Errors in one part of the processing chain often had knock-on effects elsewhere, leading Usabilla's SREs to search for a more failure tolerant design.

Steven will introduce the new stateless fluentd deployment at Usabilla, built around Kafka as a centralised, highly available log buffer. He will also introduce the new components that have been developed to adapt fluentd to be completely stateless, as well as how logs are reliably fed into Kafka from hosts all over the world. Finally, there will be a brief overview of the challenges still remaining.

Better Histograms for Prometheus - Björn Rabenstein, Grafana Labs

Robust histogram functionality was added to Prometheus long ago, to be precise in version 0.11.0. The histogram representation as we know it from Prometheus andnow also OpenMetrics is a simple yet powerful and enables many important use cases. However, it is also infuriatingly limited, mostly because of its high per-bucket cost. Björn “Beorn” Rabenstein released the above mentioned Prometheus version in February 2015 and has been dreaming about better histograms ever since. In this talk, he will explain why it is so hard for Prometheus to adopt established techniques known from various academic publications and even practical applications in other metrics-processing systems. To add a silver lining, he will share his latest findings from reignited efforts to finally break through the barriers and bring efficient high-resolution histograms to Prometheus.

OpenTelemetry Auto-Instrumentation Deep Dive - Carlos Alberto Cortez & Alex Boten, LightStep

Auto-instrumentation allows users to monitor their applications without the need to modify the code base, and immediately start gathering observability data . As part of the OpenTelemetry initiative (resulting from the merge of OpenTracing and OpenCensus), auto-instrumentation libraries will become a core feature, and will be offered across different languages (Java, Python, Ruby, Node.js, .Net, etc).

In this deep dive you will learn about the architecture of these auto-instrumentation libraries, out-of-the-box OSS libraries integrations (such as Spring, Django or Rails); how to configure them to export telemetry data to different tracing and metrics backends (such as Jaeger or Prometheus), as well as interesting challenges, such as the possibility to share OSS integrations between auto and manual instrumentation.
