15 sql server performance counters to monitor

There are hundreds of performance counters, and therefore, it can be complex to figure out just what to monitor. This is the number of processes per second that are waiting for a workspace memory grant. Next, go to SQL Server and create a new database to store your performance data. This should be close to the physical size of memory. In a normal OLTP system, workloads can support 80-90 per second. I have never gotten this to work with SQL Server authentication. Any information would be helpful. This will display the Performance Counters tab that you can see in Figure 5. Initially the Run As box will display the value SYSTEM. If you are not sure what to make the fillfactor for your indexes, your first step is to determine the ratio of disk writes to reads. At this point you’re ready to setup your connection to SQL Server. To monitor the amount of memory that SQL Server uses, examine the following performance counters: Process: Working Set. One of the best ways to monitor your server’s I/O subsystem is to use the PhysicalDisk Object: Avg. To track down the more insidious or sporadic problem, it is best to have the data in a SQL Server table, so you can query it. Set the Sample interval you want then click Finish. Data Collector can collect performance metrics on multiple SQL Server instances and store them in a single repository. Disk Queue Length for each drive is 1.66 (10/6=1.66), which is within the recommended 2 per physical disk. In this article I’ll guide you through the steps of setting up Performance Monitor to log performance data to SQL Server.

Next, you need to change the account the Perfmon run under. On the next dialog give the data source a name and use the Server dropdown to select the SQL Server instance you want to connect to.

Articles, code, and a community of monitoring experts. Watch a video summary of this article here: The first step is to use Performance Monitor to create a User Defined Data Collection which is essentially the collection of performance counters that you want to capture. Then in the Data source name dropdown select the name of the data source that you created earlier. This counter measures how busy a physical array is (not a logical partition or individual disks in an array).

This will open the ODBC Data Source Administrator.

Figure 2 – Add performance counters to the data collector set. High values for this counter may indicate insufficient memory or that the recovery interval (set using sp_configure) is too high. Once Performance Monitor is started expand the Data Collector Sets node then right click on the User Defined node and select New, Data Collector Set from the context menu. Windows Performance Monitor adds less overhead than SQL Server Data Collector and monitors more SQL Server counters. This is the amount of physical memory that is currently assigned to SQL Server. Many experts agree that memory is the most important resource with regard to SQL Server performance. Figure 3 – Selecting the ODBC Driver for a Perfmon data source. Performance Monitoring - Basic Counters. Then click Next to display the data source authentication dialog that you can see in Figure 4. Then right click on the Data Collector that you created and select Properties from the context menu. Any value greater than two indicates that SQL Server needs more memory.
You can use this syntax. In a normal OLTP system, workloads can support 80-90 per second.
