Monitoring SQL Server
To be successful at monitoring the SQL Server, the DBA needs to
understand the three major performance methodologies:
Once the DBA has a handle on these
methodologies, they can be applied in both ad-hoc and 24 x 7 styles
of monitoring. Upcoming chapters in this book will define each of
the three performance methodologies. In addition, the processes of
applying them in a SWAT-style monitoring way as well as in a
continuous around-the-clock fashion will be presented.
The DBA can only go so far in the pursuit of looking at data in real
time. Only by compiling storage, usage, and performance metrics over
time can one detect trends that could, one day, lead to database
server outages or serious performance issues.
Unfortunately, according to the Gartner group, only 30% of database
professionals actually collect and analyze data in trend analysis
fashion. This means that many DBAs are shooting in the dark when it
comes to understanding whether things are getting better or worse on
their production servers.
