Storage capacity balance¶
Requirements¶
Metrics¶
None
Planner¶
Default Watcher’s planner:
Weight planner implementation
This implementation builds actions with parents in accordance with weights. Set of actions having a higher weight will be scheduled before the other ones. There are two config options to configure: action_weights and parallelization.
Limitations
- This planner requires to have action_weights and parallelization configs tuned well.
Configuration¶
Strategy parameter is:
| parameter | type | default | Value description |
|---|---|---|---|
volume_threshold |
Number | 80.0 | Volume threshold for capacity balance |
Efficacy Indicator¶
None
Algorithm¶

How to use it ?¶
$ openstack optimize audittemplate create \
at1 workload_balancing --strategy storage_capacity_balance
$ openstack optimize audit create -a at1 \
-p volume_threshold=85.0
