Alternatively the 3 chosen tools to ship metrics and logs (CAdvisor, promtail, node-exporter) could be replaced with an all-in-one tool such as Vector or Telegraf. If you wanted to slim it down further, Netdata accomplishes what those 3 tools and Prometheus can do in a really nice UI.

If the poster hosted those services in a single node k3s or something, the kube-prometheus-stack helm chart is able to deploy a lot of those tools easily.
