Most businesses that use MSSQL servers demand high availability, and hence unexpected server downtime or sudden performance degradation can directly impact the business and its end users. Comprehensive MSSQL monitoring tools such as Applications Manager not only gives visibility into every component of your enterprise infrastructure, but also helps identify issues, and aids the process of performance tuning in SQL servers.
SQL performance tuning is the process of optimizing SQL queries to run as efficiently as possible, thereby reducing the load on the database and improving overall system performance. This is achieved through various techniques, such as analyzing query execution plans, optimizing indexes, and rewriting queries to ensure optimal execution paths. The goal is to minimize the time and resources required to execute a query, ensuring faster and more efficient data retrieval and processing. By implementing performance tuning in SQL, organizations can significantly improve the overall efficiency of their database systems, leading to faster response times, better resource utilization, and improved overall user experience.
A major aspect of the performance tuning process involves implementing processes and procedures to help optimize database queries in order to ensure that they run efficiently. Wondering where to start? Applications Manager's SQL server performance monitoring facilitates the first major step of the performance tuning process: it identifies problematic queries.
The Performance Dashboard in Applications Manager enables SQL query performance monitoring by acting as a pit stop to discover and detect queries that contribute to performance degradation of your MSSQL server. It helps identify the following categories of queries:
Indexes are distinguished lookup tables databases used to accelerate data retrieval. Similar to an index in a book, it acts as a pointer to the data in the tables. Simply put, indexes act as navigating compasses to facilitate faster data access.
Hence, tracking and monitoring database indexes can also help DBAs tune the performance of MSSQL servers. Applications Manager's SQL server performance monitoring tracks unused indexes for all databases. Removing these unused indexes can not only free disk space but can also tune MSSQL server performance.
It is important to keep track of transactions occurring in the server in order to fine tune the performance and efficiency of your MSSQL server. Too many transactions occurring simultaneously can not only degrade the performance of the server, but can also cause latency and increased response time.
With Applications Manager, become aware of the load that your server is handling by tracking Transactions/min in all the databases.This helps avoid sudden server overload and prevents server unavailability.
Enterprise MSSQL servers usually consist of numerous databases that have multiple sessions trying to access specific resources. Although blocking sessions are common in relational databases, multiple blocking sessions can cause severe performance degradation. This can result in longer response times and transaction failures that can impact the user experience.
Applications Manager helps you proactively identify blocking sessions and alerts you when memory usage and CPU time crosses a specified threshold. This paves the way towards SQL server performance tuning where you can even kill blocked sessions instantly to free up memory and tune the performance of the server.
In order to facilitate SQL server performance tuning, the best solution would be to employ the services of a monitoring tool that can give you visibility into your SQL enterprise infrastructure. Applications Manager is one such tool that is both easy to use and set up in just a few minutes.

SQL performance tuning is performed to lower the effective load on the SQL database and enhance the overall system performance by tweaking critical SQL query parameters. This is accomplished using a variety of methods, including analysing query execution plans, improving indexes, and rewriting queries to ensure the best possible execution paths. The objective is to reduce the amount of time and resources needed to perform a query, resulting in quicker and more effective data retrieval and processing. Businesses may greatly enhance the overall effectiveness of their database systems using performance tuning techniques that result in quicker response times, greater resource utilisation, and an improved user experience.
SQL monitoring tools like Applications Manager are employed to provide visibility into the database system and identify slow performing parameters that might need enhancing. Database admins can perform an in-depth analysis on how different metrics affect the behavior of the SQL database system and find ways to improve the response time of queries. They can then carry out necessary performance tuning methods based on the information gathered from Applications Manager's SQL monitor dashboard. Here is how you can start monitoring SQL query parameters that are required for performance tuning:
