27.12.2020 · Though this tutorial works with any Kubernetes cluster, it is tested on a three-node K3s cluster running on the Odyssey Blue J4105 Mini PC from Seeed Studio. Architecture Prometheus exposes a REST API endpoint that can be queried to extract any available metric. The API responds with a JSON payload for any valid Prometheus query.
Install Prometheus. Now, we are going to deploy a single instance of Prometheus. Normally, you would/should deploy multiple instances spread throughout the cluster. For example, one instance dedicated to monitor just Kubernetes API, the next dedicated to monitor nodes, and so on...

May 01, 2019 · Describe the bug I would like to monitor a k3s system. Therefore I installed the prometheus operator helm chart. Out of the box a lot of alerts are in state FIRING. A lot of rules which cover the apiserver and kubelet are not working.
05.08.2020 · We're going to go customise a Prometheus monitoring setup that includes only the parts and alerts we want to use, rather than the full-fat Prometheus setup that may be overkill for k3s clusters. Additionally, we're going to set up a Watchdog alert to an external monitor to notify us if the cluster itself is experiencing issues. You will need:
