This metric gives an idea of how many tasks are in a runnable state and trying to execute in the system concurrently.<\/p>\r\n
Sustained values for the This alert is raised when the number of tasks in a runnable state are trying to execute in the system concurrently, which can indicate CPU pressure.<\/p>\r\n The metric Average runnable task count on which this alert is based measures values for the runnable_tasks_count<\/code> column are usually a very good indicator of CPU pressure, since it means that many tasks are waiting for CPU time. The longer the queue, and the greater the number of schedulers with requests waiting, the more stressed the CPU subsystem is.<\/p>","tsql":"SELECT AVG(runnable_tasks_count) AS [Avg Runnable Task Count]\r\nFROM sys.dm_os_schedulers\r\nWHERE scheduler_id < 255\r\n AND [status] = 'VISIBLE ONLINE';\r\n","instances":true,"frequency":600,"databases":{"mode":1},"rateofchange":false,"metricenabled":true,"alertname":"CPU pressure (avg runnable task count)","alertdescription":"runnable_tasks_count<\/code> column.
