Sesión de eventos extendidos de SQL para la detección de punto muerto

¿Hay alguna manera de aumentar el tamaño del <inputbuf>elemento en el XML de punto muerto capturado por la sesión de eventos extendidos de punto muerto?

Queremos ver la consulta completa para ayudar a identificar el problema en el código de la aplicación.

Parece estar limitado a 1024 caracteres +/-. ¿Se puede aumentar?

Vea a continuación el ejemplo de XML. Puede ver que el texto de la consulta en el <inputbuf>elemento está cortado en el medio de la lista de selección:

Tiene un sqlhandlepara cada marco, por lo que puede obtener la consulta completa utilizando la sys.dm_exec_sql_textfunción:

SELECT text
FROM sys.dm_exec_sql_text(sql_handle)

sys.dm_exec_sql_text

Por ejemplo, obtener texto de algunas declaraciones de sys.dm_exec_query_stats(stmtstart, stmtend, sqlhandle en lugar de Statement_start_offset, Statement_end_offset, sql_handle en el informe XML)

SELECT TOP (100)
    CASE   
        WHEN s.[statement_start_offset] > 0 THEN  
            --The start of the active command is not at the beginning of the full command text 
            CASE s.[statement_end_offset]  
               WHEN -1 THEN  
                  --The end of the full command is also the end of the active statement 
                  SUBSTRING(t.TEXT, (s.[statement_start_offset]/2) + 1, 2147483647) 
               ELSE   
                  --The end of the active statement is not at the end of the full command 
                  SUBSTRING(t.TEXT, (s.[statement_start_offset]/2) + 1, (s.[statement_end_offset] - s.[statement_start_offset])/2+1)   
            END  
        ELSE  
            --1st part of full command is running 
            CASE s.[statement_end_offset]  
               WHEN -1 THEN  
                  --The end of the full command is also the end of the active statement 
                  RTRIM(LTRIM(t.[text]))  
               ELSE  
                  --The end of the active statement is not at the end of the full command 
                  LEFT(t.TEXT, (s.[statement_end_offset]/2) +1)

UPD

Gracias al comentario razonable de @ JohnEisbrener, debo notar que la información de los DMV será real hasta que se limpie la caché de consultas. Entonces, si espera usar esa información después de la limpieza de la memoria caché (por ejemplo, después de reiniciar el servidor), debe guardar esos datos en una tabla permanente inmediatamente después de que ocurra el evento.
