Metrics Operators
The following table lists the metrics supported operators and provides examples of queries containing each type of operator.
Operator  Description and Syntax  Examples 

Calculates the average of all the resulting time series. If grouping is specified, calculates the average for each group.



Counts the total number of time series that match the query. If grouping is specified, counts the total number for each group.



Computes the backward difference at each data point in the time series to determine how much the metric has changed from its last value in the series. This operator also assigns the value of the delta 


Calculates the maximum value of the time series that match the query. If grouping is specified, calculates the maximum for each group.



Calculates the minimum value of the time series that match the query. If grouping is specified, calculates the minimum for each group.



Parses a string to identify fields to use in the metrics queries. Each * wildcard corresponds to a specified field.



Calculates the specified percentile of the metrics that match the query. If grouping is specified, calculates the specified percentile for each group.



Segregates time series data by time period. Allows you to create aggregated results in buckets of fixed intervals (for example, 5minute intervals).



Computes a rate based on the forward difference at each time in the time series. The difference between the current and the next recorded value in a time series is scaled to a value per second. This operator also assigns the value of the rate 


Calculates the sum of the metrics values that match the query. If grouping is specified, calculates the sum for each group.



Shifts the time series from your metrics query by the specified amount of time. Can help when comparing a time series across multiple time periods
