Identify which SQL query to focus on optimizing with the help of response time analysis

SolarWinds® Database Performance Analyzer (DPA) is built to provide you with the fastest way to analyze SQL statements, identify the root cause of performance problems, show trends, and establish baselines for key performance metrics. With DPA and its 24/7 database monitoring, SQL query optimization is faster, easier, and more likely to be done right than if you try to do it on your own.

DPA’s insights on response time and wait time can help you quickly identify the problematic SQL queries and index recommendations to help you solve them. Response and wait time are some of the most useful metrics to use to gain insights on SQL query performance. DPA collates the data of all SQL statements and helps rank them based on response time. This data is then displayed through easy-to-read bar graphs in the DPA Query Performance Analyzer’s Query Details page. When you go on this page, the Top Waits chart is prominently displayed at the top, showing the query’s execution time for the time period you select. This bar graph is color-coded by type of wait with the option to see more detailed information, as well as possible resolutions, for each type of wait. This can help developers and database administrators (DBAs) identify which SQL query to focus on to optimize SQL database performance.

Monitor development, test, and production servers to solve SQL query issues before deployment

Far too often, SQL query code is not tested until late in the development and production process. Most of the time, application performance is put off until the deployment phase. This means developers won’t see how code is performing until it’s in use. If issues with performance are discovered then, the process of solving them and the delay in producing functional code can become a hassle and even a security risk. 

With the SolarWinds SQL Query Analyzer solution in DPA, you can monitor development, test, and production servers with less than a 1% load, so you can begin your query optimization in SQL Server before deployment. This tool also lets you safely monitor SQL code performance in production. Using the DPA dashboard, developers can drill down into a production database to learn how code is performing and can begin working to resolve issues and test new code before it’s expected to be put into use. By incorporating application performance into development cycles, developers can better improve SQL performance

Get all the information you need in easy-to-understand bar charts

DPA’s Query Performance Analyzer presents all the information you need about key performance indicators through easy-to-understand bar charts and associated alerts. Having easy access to this information can enable DBAs and application teams to reduce downtime, effectively optimize resources, and quickly identify which SQL query to focus on.

With DPA’s SQL Query Analyzer, you can get a unified view of database performance to help you isolate the root cause of a SQL performance issue typically in just a few clicks. With DPA’s straightforward, unified dashboard, you can monitor SQL Server, Oracle, DB2, MariaDB, Aurora, MySQL, Azure SQL, and SAP ASE from a single view. You can also monitor VMware with less than a 1% load.

With DPA, you can use a single pane of glass to see the direct correlation between system resources, helping simplify your SQL query optimization. With the SolarWinds DPA dashboard, you get an overview of all monitored instances and statuses for a full performance picture of your databases. You can also optimize SQL queries across those top RDBMS engines from the same single view using the SQL Query Analyzer.

Collect query plans in real time, so you can analyze them as needed

Query execution plans, also called query plans, tell you how an SQL query will be—or already was—executed. Since the automatically produced execution plans aren’t always optimal, it’s important to be able to look back at cached execution plans to determine if they need to be altered to optimize the SQL database.

SolarWinds DPA collects execution plans in real-time and links them with SQL statements, wait types, and other performance data. The data’s history is then stored by DPA, so you can watch for and get alerted on any changes to the plan that may have resulted in performance degradation. This data storage also means you can revisit the plan when needed to find exactly which execution plan was used. 

DPA displays the plan graphically, with pop-up dialogs when scrolling over specific steps. It also displays compilations and recompilations per second, which lets you see if executions are being reused. In addition to the important metrics DPA collects and displays, these clear visuals can help you pinpoint the reasons behind SQL query performance degradation. 

Optimize memory usage and tune insufficient SQL queries to improve performance

With DPA, you can gain insights into your memory usage and stress to better address the factors contributing to your query performance. By helping you understand your memory usage, DPA helps ensure you direct your SQL query optimization efforts toward the correct causes of performance issues.

DPA can also run table tuning analysis at the end of each day, leveraging both historical trends and current data to generate tuning advice. By catching both minor and widespread performance issues, and providing detailed, ranked input from tuning advisors, the Query Performance Analyzer in DPA is designed to help you better prioritize which issues need immediate attention and which are less pressing. This way you can streamline SQL query optimization, saving you both time and money and improving overall SQL query performance.

In addition to helping you optimize your SQL queries, DPA is built to help improve the server engine’s memory usage by reducing the number of single-use query plans stored in the memory. Single-use plans are statement plans stored in SQL server memory but are only used once. DPA enhances the server’s ability to search for and locate existing SQL statement plans instead of creating new ones.
