Deep Dive into Thanos-Part II

Monitoring Kubernetes Workloads with Thanos and Prometheus Operator

In Part I of this article we have understood the various components of Thanos and its use cases. In this Part II, we will configure Thanos with GCS ( Google Cloud Storage ) and understand how metrics can be retained for longer periods using Thanos. We will also configure Grafana to use the Thanos Query Frontend to visualize graphs from various clusters ( Thanos Queriers ).
