Hot Network Questions Why isn't the religion of R'hllor, The Lord of Light, dominant? Check if there are scan of big tables which can be avoided, and if data can be filtered based on access. Is this how many time sthe query runned, since the last server restart?Or it is based with another logic? –Rafael Piccinelli Nov 30 '15 at 15:42 @RafaelPiccinelli According to When a plan is removed from the cache, the corresponding rows are eliminated from this view The first sentence, "Returns aggregate performance statistics", tells us that the information in this DMV
There are multiple ways to determine what database a request is working in, such as the database they logged into or their current DB context, not necessarily the database they're touching You cannot delete other topics. One of the queries is exactly about the CPU usage per database.
It is still ranked by CPU but I added other totals and percents to get a better server profile. I would like to run this every hour and save the data in a table. asked 2 years ago viewed 26520 times active 3 days ago Linked 3 How do I get useful SQL Server database performance statistics? Sql Server Get Current Cpu Usage No word for "time" until 1871?
Now let's contrast the above with sys.sysprocesses. Sql Server Cpu Usage 100 Percent And the query using sys.dm_exec_query_stats is looking at mostly (maybe) what has happened since the last restart of the SQL Server service (or obviously system reboot). It condenses the data in the query_stats DMV since those records can show the same query (yes, the same subset of the query batch) multiple times, each with a different execution Related 5CPU usage on RDS instance monotonically increasing with no change to query volume1sql server instance using maximum cpu usage4One CPU in a 32-core system is getting to 100% usage and

I don't know that true CPU by database is all that measurable or useful. –Aaron Bertrand♦ Nov 19 '14 at 13:32 I usually rely on Glenn Berry's Diagnostic Information weblink First, a single query can also hide its true database parent by doing tricks like this: USE msdb DECLARE @StringToExecute VARCHAR(1000) SET @StringToExecute = 'SELECT * FROM AdventureWorks.dbo.ErrorLog' EXEC @StringToExecute The

That means that you can miss information if it ages out of cache. Also, most DMVs are reset when the server resets so they are not a true history even if these rows weren't removed when the plans expire.
There is no perfmon counter per database, unfortunately.

Essentially, it's necessary to narrow down the high CPU problem to the lowest possible level-the component which is causing high CPU.
