There
are various ways to detect the existence of problem processes in
Switch:
The Problem Alerts user preferences
allow specifying that a notification email should be sent to the system
administrator when communication (Email, FTP, local network) is
down for more than a specified time, or when an external process
fails.
The flow element corresponding
to a problem process is shown in the canvas with a red error mark,
providing obvious feedback on its problem state (see Viewing an active flow).
The Dashboard pane displays
an overview of the current problem processes at any given time.
See Viewing flow problems.
