I love using Prometheus/Grafana to monitor and tune resource usage on my Kubernetes clusters. When pods are terminated, however, the graphs are disposed of it seems.
I am looking for a solution to this problem.
For informed decisions on how to tune resource requests I need history to be kept.
Does anybody know how to keep graphs for deleted Kubernetes pods in Prometheus/Grafana.
I am currently using this deployment: https://itnext.io/kubernetes-monitoring-with-prometheus-in-15-minutes-8e54d1de2e13
