Avoid activity monitoring tool hurting SQL server’s performance

Read time: 4 minutes

Performance monitoring of SQL Server deployment tools and services has always been a crucial part of any DBA’s regular audits. It helps in maintaining and troubleshooting the queries or issues that can hurt the performance of the SQL Server.

Activity Monitor is a dedicated Microsoft tool that helps with this process. However, using this tool might cause a certain performance dip, preventing the SQL Server from reacting rapidly to any query.

Activity Monitor is available with Microsoft’s SQL Server Management Studio and is not supposed to hurt or affect the software. But the main reason behind its disturbing impact on SQL Server is the consumption of several server resources.

In this article, we will talk about this issue in detail, highlighting the best solutions to fix it.

A brief about activity monitor

A process called “observer overhead” aims to minimize the consumption of resources when monitoring the performance of any system. And that’s how tools are designed. Some of these tools reduce the collection of data to rip off the increased load during the process.

Database performance tools work by attaining a certain amount of data on specified time intervals, which is then stored either on a local data store or in another remote data store. After that, the data is simply captured at the point-in-time interval for other third-party tools, where users implement some queries for data reviewing and processing.

How it affects?

Activity Monitor is seamless in operation, but practically it slows down the processing and reactivity of SQL servers in certain instances. The issue is clear as stated above – allocation of several resources at the same time.

So, how does it affect the application? While allocating the resources, CPU clock cycles get hacked and hold the allocated memory that might have been previously allocated for processing queries and other transactions.

As a result, a surplus overhead combined with Activity Monitor to run 13 consecutive queries in a loop of 10 seconds. And this will keep the dashboard busy with the monitored stats that will be required for tracking the performance.

So, running Activity Monitor will compromise other crucial processes like TempDB, which is responsible for suboptimal server operation.

Alternate solutions

So, how can you avoid activity monitor hurting your SQL server performance? Let us see.

Final thoughts

Since performance monitoring is a crucial task of SQL Server, it is necessary to use a tool for making the process fluent. Activity Monitor might be a preferred tool from Microsoft, but it causes various other problems in the case of multitasking and fast processing. So, make sure to use the alternate options to enhance the performance of the SQL Server. If you face SQL data loss issues, you can use Kernel for SQL Database Recovery to recover the lost data. The software can check the database file and recover deleted records in SQL Server as well the severely corrupt ones. It is a guaranteed approach when the database is affected due to active monitoring
