This statistic tracks Shadow Migration requests for files or directories that are not cached and known to be local to the filesystem. It does account for both migrated and unmigrated files and directories, and can be used to track the latency incurred as part of shadow migration, as well as track the progress of background migration. It currently encompasses both synchronous and asynchronous (background) migration, so it's not possible to view only latency visible to clients.
When investigating Shadow Migration activity.
