Observability [clear filter]
Tuesday, December 11
 

10:50am

On the OSS Path to Full Observability with Grafana - David Kaltschmidt, Grafana Labs
Grafana is coming “off the wall”. To make it more useful for interactive debugging, David and his team have already integrated two pillars of observability - metrics and logs. They are currently adding tracing to complete the incident response experience. All to minimise the cost of context switching during those crucial minutes after getting paged.

This talk will demonstrate the various methods we’ve used to link the data together. Prometheus is providing the metrics. Via its histograms, request latencies can be extracted to inform each tracing span from Jaeger. Grafana also ensures that lines from your log aggregation system are annotated with span and trace IDs, as well as the other way around: associating logged values with spans.

David will show how these OSS parts should be deployed to achieve full observability in an engaging user experience that saves valuable minutes.

Water, Water, Everywhere: Making Kubernetes Audit Logs Potable - Kate Kuchin, Heptio
Audit logging in Kubernetes is a powerful tool that grants Kubernetes operators more insight into their clusters. Audit logs can tell us what happened in our clusters, when it happened, who did it, what resources were affected, and more. The problem is, even a fairly stagnant Kubernetes cluster generates millions of audit logs per week. And it's up to us to distill value out of what is largely just noise.

So, how can we isolate important audit events to better understand what's going on in our clusters?

In this session, we'll first go over what Kubernetes audit logs are and what information they provide. We'll then do a live a demo of getting audit set up on a cluster, and inspect the raw logs that are generated. And finally, we'll talk about strategies for pulling useful information out of the deluge, so we can make sense of these millions of audit logs glean actionable insights.

Observability is the Key Tenet of Running a Multi-Tenant K8s Environment - Thom McCann & Amreth Chandrasehar, T-Mobile
How do you achieve 200 Million requests per day and no down time for 2 years? T-Mobile has been driving containerized workloads for many internal application teams. Running an internal multi-tenant environment can be challenging but has significant benefits

In this session we'll dive deep into observability components such as a large scale telemetry system built on Prometheus serving 4000+ requests per second and millions of metrics over 6 clusters. This open source system is built across 3 AZs in each region (US West and US East) and is federated across multiple Prometheus clusters enabling distributed queries and limitless scale.

We'll dive deep into how our operational teams can view integrated monitoring for infrastructure, hosts, VMs, containers and application level and integrate alerts with slack, pager duty and other real-time systems.

Three Pillars, Zero Answers: We Need to Rethink Observability - Ben Sigelman, LightStep
Observability has never been more important: the complexity of microservices makes it harder and harder to answer basic questions about system behavior. The conventional wisdom claims that Metrics, Logging and Tracing are “the three pillars” of observability… yet software organizations check these three boxes and are still grasping at straws during emergencies.

In this session we’ll illustrate the problem with the three pillars: metrics, logs, and traces are just data – they are the fuel, not the car. We then reframe observability around two fundamental activities: (1) measurement and (2) explanation.

“Measurement” must be both robust and precise; “explanation” must present the larger context of distributed transactions and the role that contention plays under peak load. We present both via demos and examples to ground the session in real-world storytelling.

Cortex - Infinitely Scalable Prometheus - Bryan Boreham, Weaveworks
Prometheus is an excellent monitoring solution, however it is designed to store all metrics on one host in one set of files, which limits scalability and availability.

This talk provides an overview of Cortex, an Open Source project proposed for donation to the CNCF, which takes metrics from multiple Prometheus instances and stores them in a NoSQL database.

Outline:
- Microservices architecture of Cortex
- NoSQL back-end (DynamoDB, Bigtable or Cassandra)
- Fault-tolerance via DHT-based ingestion tier and stateless query tier
- Deployment via Kubernetes
- Architectural comparison to projects in the same area, such as Thanos and M3
- Lessons learned from operating “Prometheus as a service” for two years

Securing Application Telemetry & Tracing with SPIFFE and Envoy - Sabree Blackmon, Docker
Application telemetry, such as Prometheus metrics, distributed logs, and tracing, offer a surplus of information on how an app works, how it's performing, what it’s communicating with and how. However, even when these streams do not contain PII, this information can be invaluable to malicious actors in the days of highly distributed systems. In this talk, we will demonstrate how to use Envoy proxy and SPIRE to protect your telemetry endpoints, in both push and pull use cases, utilizing fluentd, Prometheus, and OpenTracing & Jaeger.

Understanding Microservices with Distributed Tracing - Lita Cho, Lyft
With microservices, one request can go through hundreds of nodes. Not one engineer can know all the possible paths of the request, How can engineers infer how the system behaves? Metrics? Logging? These tools have their place, but neither of these inherently constructs a journey of the entire request. What if we want to optimize the overall request latency? Figure out how many additional hops the system will make by adding a new API call? I am here to talk about how distributed tracing tells a story about your system. I will go over how you can see the entire picture of what your system looks like, and with this data, make investigate and triage systematic issues, and make impactful, data-driven, performance optimizations to your system. I will go over what tracing does well and what does not. I will also go over how we leverage Envoy and OpenTracing to the instrument.

Distributed Tracing in Serverless Systems - Nitzan Shapira, Epsagon
Serverless and FaaS naturally fit microservices architectures. Observability of such systems is very complicated, since each microservice is separated and working asynchronously from the others. Distributed tracing is a key approach to understand such systems. In serverless, there are new challenges and opportunities which make distributed tracing a very interesting and useful technique for high observability.

I will go quickly over the history of tracing and the popular tools. I will focus on the key differences between observability using distributed tracing in generic microservices environments compared to serverless. Examples from the popular cloud vendors will be shown, including full visualization of asynchronous transactions in a highly distributed serverless system, and detecting business flows across multiple asynchronous communication resources (e.g. SNS, Kinesis, and more).

Unified Observability in Kubernetes and Beyond with OpenCensus - Morgan McLean & Jaana Burcu Dogan, Google
Platforms like Kubernetes have allowed developers around the world to develop highly performant and easily configurable distributed systems. However, the techniques that developers have used in the past are no longer as effective in these environments.

OpenCensus is designed with this situation in mind: it provides libraries that automatically capture application metrics and distributed traces, attaches the correct service and workload metadata, and sends them to your backend of choice for analysis.

In this talk we will:
- Instrument a set of microservices, including custom metrics and tie-ins to OpenMetrics
- Analyze the telemetry captured from the app with common open-source tools like Prometheus and Jaeger
- Demonstrate advanced features like exporting data to multiple backends and changing configuration in realtime without requiring redeployment

See opencensus.io for more details.

Sharded and Federated Prometheus Servers to Monitor Distributed Databases - Jun Li & Viswa Vutharkar, eBay
At eBay we have developed a geo-distributed transactional document store called NuData. It is deployed on Kubernetes. The current deployment has thousands of pods across three datacenters, and is monitored by Prometheus. For scalability, our Prometheus cluster has sharded servers to monitor individual infrastructure components and federation servers to retrieve aggregated metrics from sharded servers. For high availability, each sharded/federated server is configured with an active/standby pair over its load-balancer. A routing map ( a time series) is automatically constructed by each shard server and assembled by the federation server, to direct Prometheus queries to the right servers. Today we have over 90 Prometheus servers on two datacenters to collect over 11 M metrics/60 seconds on 400 metrics (and 900 rules), to support health monitoring and performance debugging of NuData.

Collecting Operational Metrics for a Cluster with 5,000 Namespaces - Rob Szumski & Chance Zibolski, Red Hat
Kubernetes is popular to provide a multi-tenant, shared infrastructure layer for many eng teams within an org. This is great for the teams, as they have a stable, scalable cluster to build upon. However, the Ops team needs insight into resource usage, availability & more, especially once an app is running in multiple regions/clouds.

This talk will introduce the open source Operator Metering project, which collects metrics from Prometheus about Pods/Namespaces & combines it against cloud resource usage and other metrics to compute cost per Pod and other reports on a periodic interval. This capability unlocks billing for internal biz units, capacity planning, and operational knowledge of Operators running within a cluster.

At the end, we’ll show the project running against a real cluster with over 5,000 namespaces, proving the scale and insight the reports can provide to an Ops team.
