When managing large scale deployment of SQL Server instances, it is important for DBAs to setup proactive monitoring & establishing performance baselines which helps in performance tuning, capacity planning & identifying workload patterns. Attend this session to learn what data should a DBAs collect & how, to monitor & establish performance baseline in SQL Server.

Baselining means and why is it
required ?
Understand the tools available for
establishing a baseline in SQL
Server and monitoring

performance baseline tools
to understand and
troubleshoot performance
