This means that your K3s cluster can tolerate a failure and remain up and running and serving traffic to your users.

K3s is a lightweight certified Kubernetes distribution developed at Rancher Labs that built is for IoT and edge computing.

Grafana dashboards are most effective when they are layered with context.

In a previous blog we learnt about setting up a Scalable Prometheus-Thanos monitoring stack. We also learnt about how we can cluster multiple Prometheus servers with the help of Thanos and then deduplicate metrics and alerts across them. MetricFire is a Hosted Prometheus solution, and you can use our product with minimal configuration to gain in-depth insight into your environments. If you would like to learn more about it please book a demo with us, or sign up for the free trial today.
