In this case, new records are going to be sequentially placed on new pages rather than on pages that are already occupied with data create a cluster index for auto-increment columns.We can try to resolve this using one of the following methods: Such operations should be avoided if this is possible. If this value is high, it could mean that SQL Server has to execute a lot of resource-heavy operations to split pages and move a part of an existing page to a new location when inserting and updating data. Page Splits/sec - The number of page splits per second that are performed as a result of index page overflow. Excessive index fragmentation can lead to significant reductions in performance. Additionally, you can use the object’s Access Methods counters to track data size, indices and available space in the database by controlling the size and fragmentation of each server instance. Tracking the data access methods in a particular database will allow you to decide which way of increasing the query performance will be the best: adding or changing indices, sections, files or groups of files, index defragmentation or changing the query text. Physical access to database pages on the disk can be tracked with buffer manager counters.

The Access Methods object in SQL Server provides counters that help with tracking the access to logic data in a database. However, if there are long stretches of time during which the processor load is greater than 80%, your system will benefit from using more CPU cores. It’s quite natural for this counter to have short-lived actvity peaks often reaching 100%. Each processor can be assigned to an idle thread which uses unproductive processor cycles which other threads don’t use. This value can be seen as a representation of the time spent on productive work. This counter shows the percentage of time spent by the processor on performing various operations for non-idle threads. Less than 5% available memory = Critical state, needs intervention.It may prove beneficial to set the Available Mbytes threshold manually based on the following considerations: In most cases, this counter should be higher than 5000 Kb. The solution here would be to increase the amount of memory. Low values are a sign of a memory deficit. However, page faults of the former type can lead to significant latency when being processed.Īvailable Bytes - Tracks the memory (in bytes) available for the execution of various processes. Most CPUs can process the latter fault type with no considerable latency. This counter includes page faults that require disk requests, as well as faults caused by pages being not currently present in the set of memory resident pages. A page fault occurs when a program requests an address on a page that is not in the current set of memory resident pages. Page Faults/sec - This value represents the number of page faults. If the swapping value is growing, then there is a need to increase the amount of RAM or to limit the number of applications the server is running. This counter represents the intensity of page swapping, so its non-peak value should be close to zero. This is the main counter you should keep track of in times of high memory usage load and excessive page swapping. This value represents the sum of Pages Input/sec and Pages Output/sec values, while also including pages retrieved to satisfy faults in the file system cache (usually requested by applications) and noncached mapped memory files.

Pages/sec - Shows the rate at which pages are read from or written to disk to resolve hard page faults. The following system counters are commonly used to monitor the state of MS SQL Server: 1.

The Main System Counters Used for MS SQL Server Monitoring In this part of the article, we’ll look at the main system counters used to monitor MS SQL Server’s state, review the process of tempdb system database monitoring and learn more about the SQL Server performance monitor feature in dbForge Studio for SQL Server.
