I see a high CPU pressure in the SQL Server and SQL Sentry shows only the following command which consumes the CPU abnormally. I think this is an internal process of the database engine but what stuff could be triggered this command?

Note: I am sure this is only a little part of the SQL statement which is used by the SQL Server

OPEN plan_handle_cursor;

You could use monitoring tools (example Redgate SQL Monitor) where you can view, say, top 10 queries by CPU, reads etc. for a given period of time. Sort by CPU time, it will show top SQL statements that consumed most CPU. Expand any of these statements (example "OPEN plan_handle_cursor") , it will show a batch (or SP) to which your problematic statement belongs.

I am quite sure other monitoring tools (that are not free) can do the same.

You could also use free diagnostic tools, like:

  1. sp_WhoIsActive - https://github.com/amachanic/sp_whoisactive/releases
    Run it with "@get_plans = 2" parameter, to get execution plan. If you spot an "OPEN plan_handle_cursor" query in results in "sql_text" column, click on the "query_plan" column value, it will show an execution plan along with other statements in the batch

  2. sp_PressureDetector - https://erikdarlingdata.com/sp_pressuredetector

  3. sp_BlitzWho - https://downloads.brentozar.com/FirstResponderKit.zip

Update: for SQL Sentry, refer to this link: https://docs.sentryone.com/help/top-sql It contains instructions on how to use Performance Analysis Top SQL. You should be able to get execution plan and full batch text to which "OPEN plan_handle_cursor" sql statement belongs

  • Thanks for the answer but I have already tried before to post the question. SQL Sentry shows only this part of the query

  • @EsatErkec tried "sp_WhoIsActive", or "sp_PressureDetector", or "sp_BlitzWho", or Redgate, or what ? Commented Jun 21, 2023 at 17:26
  • I need more than them because it only occurred one time.
