Administration
The Administration facility allows for user management and settings setup facilities typically
needed by application administrators of Sentinel.
Common Services
All of the above described components in this business logic layer of the architecture are driven by a
set of common services. These utility services assist in fine-grain filtering (through Filter Engine) of
events to users, continuous monitoring of system health statistics (through Health Monitor) and
dynamic updates of system wide data (through Map Service). Together, these utility services form
the fabric of the loosely-coupled services that allow for unparalleled processing and scaling over the
message bus-based transport for real-time analytics and computation.
A.4.3 Presentation Layer
The presentation layer renders the application interface to the end user. The Sentinel Control Center
is a comprehensive dashboard that presents information to the user.
The presentation of event is possible through Active Views which displays the events in a tabular
form or by using different types of charts. Table Format displays the variables of the events as
columns in a table. Sorting of information is possible in the grid by clicking on the column name.

Graphical Format displays events as graphs. Stacked Bar 2D, Bar, 3D, Line and Ribbon graphs are
available for proper representation of information in graphical format.
