----------------------------------------
Resolution: Duplicate
> Add container balancer dry-run CLI for time and iteration estimates
> -------------------------------------------------------------------
>
> Key: HDDS-16180
> URL: https://issues.apache.org/jira/browse/HDDS-16180
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Sreeja Chintalapati
> Assignee: Sreeja Chintalapati
> Priority: Major
>
> Add ozone admin containerbalancer dry-run command which fetches datanode
> usage info via the existing getDatanodeUsageInfo RPC. It should use the
> cluster summary computed by the analyzer(HDDS-16173) to help in computing the
> estimates.
> Default behaviour: show estimates for all three profiles (slow, medium,
> fast). With default values for configs i.e timeouts, balancing interval,
> threshold, include/exclude nodes.
> When the user provides the --profile or --bandwidth explicitly then the
> command should show the estimates for that particular profile only.
> If the user overrides any config (i.e timeouts, balancing interval,
> threshold, include/exclude nodes) then the command should respect that to
> compute the estimates.
> Output example:
>
> {panel}
> Bytes to move: 420 TB
> Per iteration: ~4 TB
> Cycle time: ~130 min (planning + move + interval)
> Estimated iterations: 105 effective (137 with buffer)
> Estimated duration: ~9.5 days
> {panel}
