Summary: Grafana - Show Cluster growth rate based on last X hours using
promQL (was: Recon UI - Show Cluster growth rate based on last X hours using
promQL)
> Grafana - Show Cluster growth rate based on last X hours using promQL
> ---------------------------------------------------------------------

> Key: HDDS-12168
> URL: https://issues.apache.org/jira/browse/HDDS-12168
> Project: Apache Ozone
> Issue Type: Task
> Components: Ozone Recon
> Reporter: Devesh Kumar Singh
> Assignee: Abhishek Pal
> Priority: Major
>
> Recon 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. So
> for example Recon can query below API and display the growth rate over UI,
> also it can allow user to change the last X hour value.
>
> {code:java}
> http://<prometheus_host_ip>:9090/api/v1/query?query=sum(rate(scm_node_manager_total_used[1h]))
> * 100 / sum(scm_node_manager_total_used){code}
