In modern days, we run our applications as loosely coupled micro-services on distributed, elastic infrastructure as (mostly) stateless workloads. Under these circumstances, observability has become a key attribute to understand how our applications run and behave in action, in order to provide highly available and resilient service. There exist several observability signals, such as “log”, “metric”, “tracing” and “profiling” that can be collected from a running service, which we can also call pillars of observability. Using these signals, we can create real-time, actionable alerts, create panels where we can monitor applications closely, and perform in-depth analysis to find the root of the systems’ failures. Within the Go and CNCF ecosystem, there are a variety of tools that can collect and make these observable signals useful. ...

Thanos is an open-source, CNCF’s Incubated project that horizontally scales Prometheus to create a global-scale highly available monitoring system. It seamlessly extends Prometheus in a few simple steps and it is already used in production by hundreds of companies that aim for high multi-cloud scale for metrics while keeping low maintenance cost. During this talk, core Thanos (and Prometheus) maintainers, will briefly introduce basic ideas behind Thanos and deployment models and use cases. After that, to satisfy more experienced users, they will explain more advanced concepts, tips for running on the scale, and the latest shiny usability improvements. Thanks to the growing community there is much to talk about! ...

Observability is the key to understand how your application runs and behaves in action. This is especially vital for distributed environments like Kubernetes, where users run Cloud-Native microservices often written in Go. Among many other observability signals like logs and traces, the metrics signal has a substantial role. Sampled measurements observed throughout the system are crucial for monitoring the health of the applications and, they enable real-time, actionable alerting. While there are many open-source robust libraries, in various languages, that allow us to easily instrument services for backends like Prometheus, there are still numerous possibilities to make a mistake or misuse those libraries. ...
