Enterprise Status workspace
At the highest level of the Navigator Physical view is the 
Enterprise
item. The default workspace for the Enterprise is called Enterprise Status.
The Enterprise Status workspace contains four views:
Situation Event Console
The situation event console inserts a row when the status of a situation changes: Open
(including expired and reopened events), Problem, and Acknowledged. The Owner column shows who
acknowledged the event, and you can acknowledge an event from the menu. Link indicators in this view
and in the My Acknowledged Events view open the Event Details workspace or you can
right-click a 
link indicator and select another of the linked workspaces.
My Acknowledged Events
The My Acknowledged Events table view displays the events assigned to the current user. This view shows both open and closed events. Closed events are displayed to enable you to access the notes and actions taken against them.
For each event record listed, you can click the link indicator at the beginning of the event row to open
the Event Details workspace with
similar events based on the situation name; or you can right-click the link indicator to see the
other Event Details workspaces. The Event Details workspace shows any notes and attachments for the
acknowledged event, along with other related events and a link to the IBM Tivoli Open Process Automation Library where you can find analytical tools for
situations.
If the event is from an incident management agent (such as IBM Information Management), you will also see a Reference ID column and, when you open the menu to select a linked workspace, a link to the Incident Details workspace.
Message Log
The message log view displays a row for every situation in the monitored network whose status changes to any of the following values:Open, Closed, Stopped, Problem, Acknowledged, Expired, or Reopened.
Open Situations Counts - Last 24 Hours
The Open Situations Counts - Last 24 Hours is a chart view which displays a bar for every situation in the monitored network that has become true in the past 24 hours. The bar size indicates the number of times a situation event has been opened during this time.
More predefined workspaces
More predefined workspaces for the Enterprise Navigator item are accessible through the 
Workspace Gallery.
In addition, your monitoring product might have workspaces at the Enterprise level. Consult your
product help for more information.
