Metric Name 
The name of the metric. 
Unit 
The unit of the metric. 
Computing Cycle 
The statistical period of the metric. Unit: minutes. Valid values: 1, 2, 3, 4, 5,
10, 15, 20, 30, and 60.

Statistical Method 
The function that is used to aggregate log data within a statistical period. If the
value of the specified field is a numeric value, you can use all statistical methods.
Otherwise, you can use only the Count and countps methods to aggregate log data. Valid values:
 Count: calculates the number of values of the specified field within a statistical period.
 Sum: calculates the sum of the values of the specified field within the last minute.
 Max: calculates the maximum value of the specified field within a statistical period.
 Min: calculates the minimum value of the specified field within a statistical period.
 Average: calculates the average of the values of the specified field within a statistical
period.
 countps: calculates the number of values of the specified field divided by the total number
of seconds within a statistical period.
 sumps: calculates the sum of the values of the specified field divided by the total number
of seconds within a statistical period.
 distinct: calculates the number of unique values of the specified field within a statistical
period.

Extended Field 
Performs basic operations on calculation results. For example, after you set the Statistical
Method parameter to aggregate log data, you specify a field as TotalNumber to calculate
the total number of HTTP requests. At the same time, you specify another field as
5xxNumber to calculate the number of HTTP requests whose status code is greater than
499. In this case, you can specify an extended field to calculate the server error
rate by using the following formula: 5XXNumber/TotalNumber × 100%.

Log Filter 
Filters log data. This parameter is equivalent to the WHERE clause in SQL. For example,
if you want to monitor logs in which the value of the level field is ERROR, set the
parameter to level>=ERROR .
The name of the log field that you use to filter data cannot contain Chinese characters.

GroupBy 
The dimension based on which data is aggregated. This parameter is equivalent to the
GROUP BY clause in SQL.
Log data is grouped by the specified dimension. If you do not specify a dimension,
all data is aggregated based on the specified aggregate function.
For more information, see GROUP BY clause.

Select SQL 
Converts the statistical methods that you specify to an SQL statement. This parameter
indicates how data is processed.

Application Group 
The name of the application group. The metric is added to the specified application
group.
