> Grafana dashboard can show cluster growth rate on an hourly basis or last X
> number of hours selected by user. This information will be computed based on
> prometheus metrics if prometheus service is running in cluster.
>
> *promQL:*
> {code:java}
> sum(rate(scm_node_manager_total_used[1h])) * 100 /
> sum(scm_node_manager_total_used){code}
> Here 1h can be changed based on user selection, but default it will show in
> last 1 hour, what is the growth rate. Above promQL shows in percentage.
