Don’t hardcode dfm13nk97y9kwf. Use ${datasource} like the other panels. Remove the hardcoded UID from the variable default too.

Done. Also updated DatasourceVariable spec to "default"

should this be sum(container_balancer_metrics_data_size_moved_gb_in_latest_iteration) instead?
since the title of this panel shows 'Size Moved (Latest)'

Thanks for catching this !
For the latest run stats , was trying to get delta using total data size moved metrics "container_balancer_metrics_data_size_moved_gb"
- I was trying to apply rate with aggregate function sum (), which makes query invalid , to fix that it requires to bind with increase function .
Realised this is not even required we already have another metrics for latest _iteration
"container_balancer_metrics_data_size_moved_gb_in_latest_iteration"
Fixed this now :
