Prometheus & Grafana

Introduction

It has been decided that it would be better if we had some detailed knowledge of what is happening with the VMs and indeed on the host Pear as well. The Proxmox GUI does give an approximation of what the state of resources are on the Host and VMs but it does seem to be a bit vague and out of date. It is with the Proxmox lack of detail that prompted the installation of Prometheus and as Prometheus does not do justice to the data that it collects Grafana has also been installed, further long term data storage requires some thing like Victoria Metrics is needed. So what started out to be a simple data collection issue ended with a suite of VMs to gather, store and view the metrics of the Pear suite.
