In this article, we’ll discuss how to monitor SQL performance in real time. We’ll cover two methods: using the built-in Windows Performance Monitor tool and using the open-source PerfMon tool. We’ll also provide some tips on what to look for when monitoring SQL performance.
SQL performance monitoring is a critical part of maintaining any database-driven application. Poorly performing SQL queries can lead to slow performance, data inconsistencies, and even data loss.
There are many tools available for monitoring SQL performance, but most require significant configuration and setup before they can provide useful information. Additionally, many tools only provide information about past performance, which can make it difficult to identify and fix current issues.
In this article, we’ll introduce you to a new tool that makes it easy to monitor SQL performance in real-time: PerfMon+.
PerfMon+ is a free and open-source tool that allows you to see all SQL queries that are currently executing on your database server(s). It also provides information about query execution times, memory usage, and more.
Installing PerfMon+:
PerfMon+ is available for Windows, Linux, and macOS. You can download the latest version from the PerfMon+ website.
Once you have downloaded the appropriate version for your operating system, you can install it by running the installer and following the on-screen instructions.
Configuring PerfMon+:
After installing PerfMon+, you will need to configure it to connect to your database server(s). This can be done via the PerfMon+ interface or by editing the configuration file directly.
To connect to a database server via the PerfMon+ interface, select the “Add Server” option from the File menu. This will open the “Add Server” dialog box.
In the “Add Server” dialog box, you will need to enter the hostname or IP address of your database server, as well as the port number and credentials for a user with access to the server.
Once you have entered all of the necessary information, click the “OK” button to save your changes and close the dialog box.
You should now see your database server listed in the PerfMon+ interface. You can click on it to expand it and see all of the available options.
Monitoring SQL Queries:
To begin monitoring SQL queries, select the “SQL” option from the list of available monitors. This will open the “SQL Monitor” interface.
In the “SQL Monitor” interface, you will see a list of all SQL queries that are currently executing on your database server. For each query, you will see information about the execution time, memory usage, and more.
You can also click on any of the columns to sort the list of queries by that column. This can be helpful if you want to quickly find the longest-running or most-memory intensive queries.
