SIG Instrumentation Introduction And Deep Dive

Conference: KubeCon + CloudNativeCon North America 2022

2022-10-28

Authors: Han Kang, David Ashpole, Damien Grisonnet

Summary

The presentation discusses the importance of observability in Kubernetes and the role of the SIG Instrumentation group in maintaining and improving the stability and quality of metrics.

The SIG Instrumentation group is responsible for maintaining and improving the stability and quality of metrics in Kubernetes.
Observability is important in Kubernetes to identify and fix issues related to latency regression and other problems.
The group is working on building an automated documentation to help users understand and use metrics more effectively.
The group is also working on adding a beta stage to the stability framework to improve expressiveness.
The group is actively seeking new contributors and offers various ways to contribute, including code reviews and documentation.
The group maintains several sub-projects, including CubeSat Metrics, Metric Server, and Primitives Adapter, which are used for auto-scaling and adapting queries.
The group also maintains the logging infrastructure in Kubernetes.

The CubeSat Metrics project generates metrics and exposes them based on third-party applications that are not meant to be monitored, such as the Kubernetes API. This is useful for investigating issues related to deployments that have not completed or other problems. The Metric Server and Primitives Adapter projects are used for auto-scaling based on metrics, and the group is working on building an automated documentation to help users understand and use metrics more effectively.

Abstract

Kubernetes SIG Instrumentation is responsible for ensuring high quality and consistent instrumentation across the Kubernetes project. We will begin with an introductory overview of the efforts the SIG Instrumentation has worked on in the past and is currently working on. This deep dive session will go into detail about currently ongoing efforts happening within SIG Instrumentation to share with the audience concrete pieces of work to encourage future collaboration. Software engineering and operations are both disciplines practiced in SIG Instrumentation, and any experience will help the special interest group's mission. Join this session to learn how to get involved in SIG Instrumentation to make instrumentation even better!
