    fixed CPU UsagePercent Error (#2222)
    
    fixed CPU UsagePercent Error
    The cpu usage storage longitude should be one percent, not one in ten 
thousand. When the storage unit is one ten thousandth, as long as the usage 
rate does not exceed 100%. Stored values are less than one. When the current 
query is forced to be converted to a long type, it will always be 0. This is 
not correct.
