Additional Node Exporter Metrics

It is important to know that many collectors of Prometheus Node Exporter are disabled by default as a matter of practice. For more information, refer https://github.com/prometheus/node_exporter#disabled-by-default.

In Siebel CRM Observability - Monitoring solution, these can be enabled by providing a --collector.<name> flag under "args" section of node-exporters-daemonset.yaml and after that one must increment the "version" in the file <namespace>-helmcharts/node-exporters/Chart.yaml. This will deploy the necessary collector on OKE as part of GitOps.
