The O11y toolkit is a set of utilities that help you debug, augment, and manage your open source observability stack.

Grafana configuration can nowadays be fully done as code, which enables code review, code reuse, and in general better workflows when working with dashboards.

This talk will present Grafonnet, a Jsonnet library to generate Grafana dashboards and some tips and tricks about how to use it efficiently and how to manage fully your grafana instances from code. We will also explore how Jsonnet and Grafonnet enable collaboration on dashboards, using Mixins and explain how to push dashboards to Grafana, either using Kubernetes, or direct to the Grafana API.

• Presentation of Grafana provisioning as code features
• Presentation of Grafonnet
• How to make reusable components with jsonnet
• How to include raw json
• How to link both (jsonnet -m to generate a folder)
• How to make PR efficient (generate grafana snapshots on merge requests)
• Jsonnet Mixins

One of the reasons we collect metrics is to be able to alert on them. This presentation will introduce you some concepts of PromQL, prometheus and alertmanager to highly improve the quality and reliability of your alerts. This talk will cover different topic, including: - Reducing flapping alerts - Hysteresis - "Time of the day" based alerting - Computed thresholds with data history

Relabeling is a powerful feature of Prometheus but it is also quite specific to the project. This talk will explain and demonstrate relabeling, with some real use cases. After the presentation, you will understand relabeling and stop to copy/paste relabeling rules you don't understand.
