Data Movement Shadow migration bytes

Data Movement: Shadow migration bytes

This statistic tracks total Shadow Migration bytes per second transferred as part of migrating file or directory contents. This does not apply to metadata (extended attributes, ACLs, etc). It gives a rough approximation of the data transferred, but source datasets with a large amount of metadata will show a disproportionally small bandwidth. The complete bandwidth can be observed by looking at network analytics.

When to check

When investigating Shadow Migration activity.

Breakdowns

Breakdown
Description
file name
The file name that was migrated. Using this breakdown allows hierarchy mode to be used, so that filesystem directories can be navigated.
project
This shows the project which contains a shadow migration.
share
This shows the share which is being migrated.
