High values for this counter indicate memory pressure or insufficient memory. This counter monitors the number of dirty pages per second, which are flushed to disk when SQL Server invokes the checkpoint process. SQL Server: Buffer Manager: Checkpoint Pages/sec If the value of this counter shows a higher value continuously more than 20, we will have to increase the memory to the system or optimize memory-intensive operations. It means the total number of times the Lazy Writer process moves dirty pages from the buffer to disk. This counter shows us the total number of Lazy writes performed in a second. SQL Server: Buffer Manager: Lazy Writes/sec Any value greater than two indicates that SQL Server needs more memory. It displays the number of requests per second where data requests stall as there are no buffers available. This counter helps to identify a sign of memory pressure or insufficient memory in the server. SQL Server: Buffer Manager: Free List Stalls/sec Higher the value better the memory health. But It is best to compare this value with the system configuration. This counter indicates the average number of seconds in which a data page remains in the cache. Page Life Expectancy is also an important counter for measuring memory pressure for the system. SQL Server: Buffer Manager: Page Life Expectancy The ideal value for this counter is more than 90. If the value of buffer cache hit ratio for our server is 94 it means 94% of total requests for data have been processed using data cache. It is an important counter which shows the percentages of using data cache. SQL Server: Buffer Manager: Buffer Cache Hit Ratio If this value shows constantly below min server memory and max server memory then we can understand that we have set too much memory for the SQL Server. This counter value shows whether we have set optimum value in min server memory and max server memory configuration or not. Process: Working Set counter shows the amount of memory a process can use.

This will give an exact picture of whether SQL Server is causing this paging issue or not. Next, we will monitor the Memory: Page Faults/sec counter to ensure that the disk activity is not because of paging. The high value of counter Memory: Pages/sec could indicate excessive paging. It means transactions are getting enough memory that is why they are using disk to process their requests. A high value of Pages/sec indicates intensive memory activities like reading from and writing to disk. The average Pages/sec value should be below 50. The high value of this counter could indicate excessive paging.

When a process requests a data page that is not in memory, it will be taken from the disk to memory. This counter indicates the total number of pages that are either read from the disk or written to the disk due to page fault. We can use this information to and ensure that memory bottlenecks do not happen in SQL Server. The low value of this counter shows the memory shortage on the server. We can check the available memory with the help of counter Available Bytes under object Memory. Some commonly used Perfmon Counters for memory usage: 1. Select * from sys.dm_os_performance_countersīy default, SQL Server changes its memory requirements dynamically, on the basis of available system resources. We can run the below command to get all performance counters and their respective values using DMV sys.dm_os_performance_counters. Perfmon Counters for Memory Usage – Counters Available Today let’s see some top performance counters to identify SQL Server Memory pressure. Here a Bobcares, we use perfmon counters as a part of our Server Management System for our customers using SQL. This will help us to get a better understanding of the memory usage in the server.

We can use Windows PerfMon utility to gather current values of all given performance counters. Sometimes, the server will face memory issues which in turn reduces the performance of running transactions. Memory is one of the important system resources that SQL Server uses to process their transactions.
