SQL Server checks CPU usage. At noon today, a friend asked me to help him check the database. The operating system is Windows2008R2, the database is SQL2008R264-bit 64 GB memory, and the 16-core CPU hardware configuration is still relatively high, he said that the server is running Kingdee K3 software, and there are multiple databases in the database instance. He

Sometimes because the server security problem can not be directly run, we may use the following

Add the following script:

-- One way to detect CPU pressure is to calculate the number of worker processes in the running state,-- You can obtain this information by executing the following DMV query:
SELECT COUNT(*) AS workers_waiting_for_cpu,t2.scheduler_idFROM sys.dm_os_workers AS t1, sys.dm_os_schedulers AS t2 WHERE t1.state='RUNNABLE' AND t1.scheduler_address = t2.scheduler_address AND t2.scheduler_idGROUP BY t2.scheduler_id
