The data flow element is a part of a SSIS package that contains different type of data flow components:
- Source components – make data from different types of data sources available to a data flow
- Transformational components – aggregate, merge, distribute, and modify the data inside the data stream, and
- Destination components – load the data from the data flow into different types of data sources or create an in-memory dataset
Monitor SQL Server queries – find poor performers – the out-of-the-box solution
SQL Server monitoring includes isolating processes that cause performance issues and fixing them. Commonly monitored performance metrics, such as page reads and writes per second, processor utilization, network usage, memory usage, etc. show the SQL Server status. For further analysis, it’s necessary to monitor what is happening on SQL Server and causes these metric values. This is where query monitoring comes into play.

September 30, 2014Monitor SQL Server queries – find poor performers – Activity Monitor and Data Collection
Monitoring and diagnosing SQL Server performance requires monitoring performance metric values, but also understanding these metrics and their relation to other metrics, knowing metric normal values, monitoring resource intensive processes and queries, etc.
September 16, 2014Operating System (OS) performance monitoring
Efficient SQL Server performance monitoring includes monitoring of operating system, SQL Server, and database performance. In How to monitor your SQL Server instances and databases, we presented tools for monitoring the latter two performance metrics, In this article, we will present tools that provide operating system performance monitoring.
July 16, 2014How to be proactively alerted of SQL Server performance problems
When it comes to monitoring SQL Server performance, there are a few native SQL Server solutions that provide out of the box performance monitoring. We have written about some of them here: A DBA guide to SQL Server performance troubleshooting – Part 2 – Monitoring utilities.
June 27, 2014How to monitor your SQL Server instances and databases
Monitoring SQL Server instances and databases provides information necessary to diagnose and troubleshoot SQL Server performance issues, as well as to fine tune SQL Server. Optimal performance is not easy to define and set, as there is usually a trade-off between multiple software and hardware factors. It also depends on your environment, business requirements, and company policy.
