Performance dashboard is developed for SQL Server 2005 which provides useful information about the server, in simple it will give you an performance overview of entire SQL Server. If you worked with SQL Server 2005 then you might be familiar with this tool. Unfortunately they didn’t provide or updated the tool to work with SQL Server 2008\R2, however based on user request we have done an workaround to make SQL 2005 reports to work with SQL 2008\R2. The good news is now MS have upgraded performance dashboard to SQL Server 2012 which now includes extended event trace details.
Performance counters are useful to gather information about server status and we can analyze the server status later using these data. In my environment one of my client is not ready to pay or buy metrics tools (normally we will be using BMC, HP etc). Our windows team has written they own custom scripts to capture the counters related to them, then it comes to our team how we are going to capture these data. Immediately it strikes my mind that we have a DMV sys.dm_os_performance_counters to get SQL performance counter values. So I thought of utilizing this procedure to get SQL Performance counter values and storing it in a table which will help us in the future to analyze the data.
Few of my friends who wish to do a performance tuning in their servers, they asked me what are the counters that they should check that gave me an idea to prepare this document and publish across.
