  SQL Server Tips by Robin Schumacher

Monitoring SQL Server

To be successful at monitoring the SQL Server, the DBA needs to understand the three major performance methodologies:

  • Bottleneck Analysis

  • Workload Analysis

  • Ratio Analysis

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.

Analysis

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.
