T4K Integration with Observability Stack

The Observability Stack is a pre-packaged distribution for monitoring, logging and dashboard interfaces which can be installed into any existing Kubernetes cluster.

Introduction

The Observability Stack is a pre-packaged distribution for monitoring, logging, and dashboarding and can be installed into any existing Kubernetes cluster. It includes many of the most popular open-source observability tools with Prometheus, Grafana, Promtail**,** and Loki. The observability stack provides a straightforward, maintainable solution for analyzing server traffic and identifying potential deployment problems.
