-- Example of monitoring SP:Completed events for a specific stored procedure
SELECT
    EventClass,
    TextData,
    LoginName,
    HostName,
    ApplicationName,
    StartTime,
    EndTime,
    Duration,
    CPU,
    Reads,
    Writes
FROM
    fn_trace_gettable(NULL, DEFAULT)
WHERE
    EventClass = 12 -- SP:Completed
    AND EventSubClass = 1 -- Success
    AND ObjectName = 'YourStoredProcedureName';
                
            

4. Troubleshooting Common Issues
