This allows future analysis on the created snapshots. Regions may optionally support triggering snapshots on demand. +Snapshot identifiers are scoped to the devlink instance, not a region. +All snapshots with the same snapshot id within a devlink instance +correspond to the same event. + The major benefit to creating a region is to provide access to internal address regions that are otherwise inaccessible to the user. |
