How to Monitor SQL Server Database Performance

By Staff Contributor on June 15, 2021

Without SQL monitoring tools, database administrators have to create their own solutions for monitoring SQL database performance. This exhausting and frustrating process distracts from more important work, and these manual SQL monitoring solutions could lead to errors. Luckily, SQL monitoring software offers a faster and more effective solution.

A database performance monitor for various databases, including SQL Server, has to work across many servers and connect all the dots from across an entire IT infrastructure. It allows you to manage your relational database management system (RDBMS) and enables the discovery and simple display of SQL Server database performance metrics, which you can then reference to better understand your SQL Server needs, capabilities, and opportunities for the future.

The Importance of SQL Server Database Performance Monitoring

Monitoring your SQL Server performance, health, and usage metrics will help you stay informed and up to date on how your SQL Server is functioning. This is crucial to maintaining optimal SQL Server database performance and provides helpful analytics for identifying performance tuning opportunities and other areas for growth.

The metrics found while monitoring your SQL Server database could also be used to discover and diagnose critical performance issues. Within the vast server metrics collected by SQL Server monitoring, it can be difficult to know where, when, and how to investigate a problem to uncover its root source. Many SQL Server performance metrics could indicate resource contention, error conditions, bottlenecks, and other complications.

Collecting these metrics is only the first step in the process of performance issue diagnosis, a critical aspect of SQL Server database performance monitoring. If you can properly organize and comprehend the vast amount of metrics available to you through effective SQL Server performance monitoring, you can solve current SQL performance problems as well as prepare for future SQL performance issues, and stop them from arising at all.

How to Monitor SQL Server Performance

The easiest and most efficient way to perform SQL Server database monitoring is to invest in a SQL Server performance monitoring tool. These applications are designed to collect important SQL Server metrics and display them using accessible visualizations, which in turn allow you to discover ways to improve overall SQL Server performance.

Although SQL Server database performance monitoring tools are certainly powerful, it’s still unwise to sit back and let them do all the work. SQL Server database performance monitors are designed to help you perform effective SQL Server monitoring, not simply do the tasks for you. I’ll list the three main types of performance problems you could encounter while monitoring your SQL Server performance and functionality.

1.   Chronic Performance Problems

If your SQL is consistently responding slowly, isn’t improving, or is getting worse over time, you must pinpoint and address the problem as soon as possible. Before jumping to costly conclusions such as increasing your resources, updating system technologies, or “buying more metal” (adding devices to your SQL Server), try to tune your SQL Server using metrics collected through SQL Server database performance monitoring. You’ll be surprised at how a few small fixes of rogue queries could improve SQL Server speed, health, and overall performance.

2.   Intermittent Performance Problems

Every database encounters complications, but you don’t want these sporadic issues to spawn into performance crises. It’s easier to solve intermittent SQL performance problems once you determine when, where, and under what conditions an issue occurs. Monitoring your SQL Server database throughout time will present you with historical records of previous metrics and indicators, which you can compare to present-day problems.

3.   Acute Performance problems

If you aren’t constantly monitoring SQL Server performance, small problems that go unnoticed could yield big issues. Even tiny delays and complications that never expand to full-blown crises could result in user frustration, especially consistentlyslow SQL Server response times.

Databases can be prone to chronic, intermittent, and acute performance problems. It’s best practice to monitor your SQL Server to ensure optimal performance. A SQL Server database performance monitoring tool will help you gather and make sense of vital performance metrics, enabling you to easily discover root sources of issues and spot areas in need of improvement.

SQL Server Database Performance Metrics

To effectively monitor SQL Server database performance, you should have a basic grasp of certain SQL Server database performance metrics. There are many SQL Server performance metrics you can uncover, and this is by no means an extensive list—however, these metrics are, in my opinion, particularly useful and important to understand.

SQL Server Database Performance Metrics

Batch Requests/Sec

The batch requests/second metric measures the rate of batches received per second. SQL query batches consist of two or more SQL statements, or even a single SQL query with the same effect as multiple SQL statements.

Last_elapsed_time

This SQL Server database performance metric demonstrates the time it took, in microseconds, to complete the most recent task or plan execution.

Disk Usage

Use this performance metric to find out how much disk space is being used by data or indexes in a given table. You can custom select which table or tables you’d like to view the disk usage of while performing this metric.

Used Memory

Similar to the above metric, the used memory SQL Server performance metric displays the amount of memory used in a resource pool, measured in kilobytes.

CPU Usage Percent

This SQL Server database performance metric can be deployed to find the percentage of your system’s CPU (Central Processing Unit) used by all workload groups of a given resource pool.

Disk Read IO/Sec and Disk Write IO/Sec

These two performance metrics both measure input and output time. Disk read IO/sec displays the count of disk read operations in the last second per resource pool, while disk write IO/sec displays the count of disk write operations in the last second per resource pool.

User Connections

The user connections SQL Server database performance metric will show you how many users are connected to your SQL Server at the time of measurement.

These SQL Server database performance metrics can allow you to access crucial information you can then analyze to more effectively monitor your SQL Server database. Again, these are just a few examples of useful SQL Server performance metrics—many metrics can offer more information on how to monitor SQL Server performance.

There are lots of options to choose from when it comes to SQL database performance monitors. Each tool comes with its own perks and downfalls, as well as other unique attributes and opportunities.
