    • Instance

      All instances that you specify to be inspected are inspected one by one. All instances that encounter critical issues, major issues, minor issues, and prompt issues are listed.

    • Path

      All paths that you specify to be inspected are inspected one by one. All disconnected paths are listed.

    • Event

      All events that occur during the inspection cycle are listed. The numbers of issue events, risk events, and issues to be resolved are displayed.

    Note

    You can add, delete, change, and query inspected instances and paths. You can specify up to 20 instances and 20 paths as inspected objects for an inspection task.
