This might be too tech minded for some people here. Can we chop it down to a
simple version? I understand this one fine since I deal with all of this
stuff.

In information technology, a dashboard is a user interface that, somewhat
resembling an automobile's dashboard, organizes and presents information in
a way that is easy to read. However, a computer dashboard is more likely to
be interactive than an automobile dashboard (unless it is also
computer-based). To some extent, most graphical user interfaces (GUI

.html>s) resemble a dashboard. However, some product developers consciously
employ this metaphor (and sometimes the term) so that the user instantly
recognizes the similarity.a product might obtain information from the local
operating system in a computer, from one or more applications that may be
running, and from one or more remote sites on the Web and present it as
though it all came from the same source. Hewlett Packard developed the first
such product, which began as a tool for customizing Windows desktops. Called
/Dashboard/, the HP product was subsequently acquired by Borland and then a
company called Starfish. Microsoft's /Digital Dashboard/ tool incorporates
Web-based elements (such as news, stock quotes, and so on) and corporate
elements (such as e-mail, applications, and so on) into Outlook. Dashboards
may be customized in a multitude of ways and named accordingly, generally,
for example as a general /corporate/ or enterprise

A software-based control panel for one or more applications, network devices
or industrial machines. Dashboards display simulated gauges and dials that
look somewhat like an automobile dashboard.
What is the SQL Server DBA Dashboard?
The SQL Server DBA dashboard tool is both a DBA and a TSQL programmer tool.
The main goal of this tool is to allow DBAs and programmers to quickly
identify performance, SQL Agent and disk space issues associated with a
single instance of SQL Server. The dashboard tool can be installed and run
against any SQL Server 2005 SP2 or SQL Server 2008 instance.
The dashboard provides 39 different performance and disk space related
reports with a single click from the main dashboard page. These different
reports provided information in the following areas:
* Identifies the worst performing TSQL Statement and Stored Procedures,
based on different criteria like CPU, I/O and elapsed time
* Performance counter measurements
* Shows summarized and detailed SQL Server Agent Job failures
* Displays CPU consumption overtime
* Reports on Index Fragmentation
* I/O usage by database <#>
* Tracks backup history
* Tables without indexes
* Unused and missing Indexes
There are two different dashboards within the SQL Server DBA <#> Dashboard.
There is one dashboard for DBAs and another one with a subset of reports
targeted for SQL Server programmers/developers <#>. The main reason for
having two different dashboards has to do with permission. The
programmer/developer dashboard only requires "VIEW SERVER STATE"
permissions; where as the SQL Server DBA Dashboard requires "sysadmin"
permissions.
Architecture/Components that make up the SQL Server DBA Dashboard:
The dashboard is made up of a single DLL, a database (SS_DBA_Dashboard), a
SQL Server Agent job and a series of Reporting Services RDL files. As
already stated the SQL Server DBA Dashboard contains two different
dashboards, one for DBAs and another for programmers.
The DLL file contains most of the code used to obtain the information
displayed in the dashboard reports. The DLL assembly is used to create
external stored procedures in the SS_DBA_Dashboard database. In additions to
SPs being created in this database there are a couple of tables to hold a
small number of statistical records. This database should grow very little,
if any after the first use of the dashboard.
The DLL and database needs to be installed on each SQL Server instance you
want to monitor with the dashboard tool. The RDL files can be stored in a
single location or multiple locations. The RDL files are designed to only to
be executed from within SQL Server Management Studio. In fact, only two RDL
files "DBA_Dashboard_Main.rdl" and "Programmer_Dashboard_Main.rdl" files
should be referenced when bringing up a Custom Report from within SSMS.
These two RDL files pass parameters to the other RDL files, so if you try to
invoke the other RDL files directly from SSMS they will fail.
Any instance where the DLL and SS_DBA_Dashboard have been installed can be
monitored using the two dashboards. The two main RDL files mentioned above
can be rendered on any client computer that has SSMS installed. The only
requirement is that the client computer be running SQL Server SP2, the
user/computer can access the RDL files, a valid registration can be made
between the client computer and the server being monitored with SSMS, and
the user using the dashboard has the permission to execute the SPs in the
SS_DBA_Dashboard database.

forever. It's one thing to be melancholy and one thing to be
sophisticated, but when you get the two of them together in a way
people can relate to, then I think you're on to something. You want
the sophistication to lie in the purity of the sound, the beauty of
the arrangements, and the quality of the performances."-Trumpeter
