This set of features provides some flexibility for varying join types, multi-statement table valued functions, and memory grants. In this article, Robert Sheldon explains the three features that make up Adaptive Query Processing … Read more
If you are using filtered indexes in SQL Server, it worthwhile monitoring the UnmatchedIndexes warning, it can give us very interesting insights. Filtered indexes and parameterized queries are terrible enemies. I explained a bit about parameterized queries in my article about how to identify them using query store, you can read it here. When a … Read more
If you're making a report from table-based data, an MS Word document is often a good option. In the second part of his introduction to SQL Server best-practice monitoring, Laerte Junior shows how to use PowerShell scripts to create a Word-based report with colour-coded alerts where there are problems or best practices aren't being followed.… Read more
By reading performance counters from services such as SQL Server or Exchange, you can get a wealth of performance information. By automating the process of gathering and storing appropriate counters, you can routinely check a range of devices quickly using visual tools such as PerfMon. By then creating your own counters, you can add counter-based metrics to anything that can be measured programmatically, such as services, applications, processes such as ETL, or deployments. … Read more
WMI (Windows Management Instrumentation) is the basic way of querying and changing basic information about any windows server, including SQL Server or Exchange Server. It provides a logical structure and representation of systems and services that are hosted on the server and is essential for anyone who is keen to automate routine monitoring and administration work via PowerShell, especially where many servers are involved in the task.… Read more
SQL Server Data Collector, together with Management Data Warehouse, is a fine and useful component for gathering information centrally about how SQL Server instances are being used, and thereby keeping an eye out for problems. It comes into its own when you have figured out how to configure it to run on maybe hundreds of instances using Central Management Server. Dennes describes how to tame the system so that it scales.… Read more
The Project Deployment Model introduced in SSIS 2012, which was explained in the first part of this series, speeds up the deployment of database projects in which there may be hundreds of SSIS packages per project. Not only that, but deployments can be configured differently for each environments such as test and staging, and there are now ways of monitoring the status and performance of packages and of versioning the SSIS Catalog.… Read more
When you're monitoring SQL Server, it is better to capture a baseline for those aspects that you're checking, such as workload, Physical I/O or performance. Once you know what is normal, then performance tuning and resource provisioning can be done in a timely manner before any problem becomes apparent. We can prevent problems by being able to predict them. Louis shows how to get started.… Read more
SQL Monitor comes with plenty of metrics, but there are always going to be things that you want to measure that can't be done 'out of the box'. Taking database mirroring as an example, Grant shows that custom metrics can be used to monitor and alert whatever aspect of SQL Server or database that you need.… Read more
It is sensible to check the performance of different solutions to data analysis in 'lab' conditions. Measurement by instrumentation makes it easier to develop systems that are efficient.… Read more
Extended Events provide a way of unintrusively monitoring what's going on in a SQL Server instance. Unlike SQL Server Profiler and SQL Trace, it has little performance impact. Now, in SQL Server 2012 SSMS, it is relatively easy to use, as Robert Sheldon shows.… Read more
PowerShell has radically improved the ease of monitoring and adminstering Windows-based servers, and automating routine processes. The visionary leader of this project is Jeffery Snover, who is now Lead Architect for both Windows Server and System Center Datacenter. … Read more
PowerShell is worth using when it is the quickest way to providing a solution. For the DBA, it is much more than getting information from SQL Server instances via PowerShell; it can also be run from SQL Server as part of a system that helps with administrative and monitoring tasks. Laerte explains how.… Read more
Simple-Talk's Melanie Townsend sits down with Red Gate's Matt Lee to talk about their newest adventure in cloud-based monitoring for SQL Server: migrating their popular SQL Monitor tool to run as a hosted service on Amazon's cloud platform, AWS… Read more
You can save a lot of time by using the SSIS Troubleshooting tools. These enable you to work with reduced data samples, monitor row counts, use data viewers, configure error-handling and monitoring package execution. Although you can develop SSIS packages without them, it is so much easier once you're familiar with these tools.… Read more
