Server CaseSQL Servers: Using Monitoring Counters
SQL server counters are special tools used within SQL server monitoring. They grant you the ability to measure the different elements of SQL server performance. Gathering this data over a period of time lets you view past trends to learn how to optimize your server for the future. These counters can be utilized for specific metrics of your choice. Using these counters will make it fast and simple to find and fix SQL server performance issues.
Discover more SQL Server monitoring tactics.
Here are 5 common SQL server counters you could use while optimizing your SQL server.
1. Buffer Manager: Page Life Expectancy
A counter of page life expectancy will measure the amount of time a page stays in the buffer cache. Their unit of measure is in seconds. If a page remains in memory it does not require SQL server queries to read from a disk. The performance of the system will increase with increased page life expectancy.
2. Batch Requests/Second
Batch requests/second measure the number of batches SQL Server receives per second. It shows the activity that a SQL server is currently processing. A high number means that there are a higher amount of query executions. Properly optimizing a SQL server entails taking these measurements often to see how the SQL server is performing over time.
3. SQL Compilations/Second
SQL compilations/second is the measurement of how many times a SQL server can compile an execution plan in one second. This is a process that is known to be very resource intensive and could potentially hurt the performance of your SQL server. Comparing this measurement against batch requests/second allows you to identify whether or not compilations are hindering performance.
4. Buffer Cache Hit Ratio
This ratio will show how many times SQL servers find data pages in their buffer cache when requested through a query. Performance improves as the number reaches closer to 100. Essentially it means that a SQL server was able to grab necessary data from memory and not from a disk.
Learn about the benefits of SQL Server optimization.
5. Lock Waits/Second
From time to time the SQL server will need to lock system resources to ensure it can deal with many users utilizing the system at the same time. Lock waits/seconds is a measurement that counts how many times a SQL server couldn't retain a lock. Being unable to retain a lock can hinder SQL server performance. The ideal SQL monitoring target is zero, and performance will suffer as the numbers get higher.
