Examples of RateOptions

net.opentsdb.core.RateOptions
Provides additional options that will be used when calculating rates. These options are useful when working with metrics that are raw counter values, where a counter is defined by a value that always increases until it hits a maximum value and then it "rolls over" to start back at 0.
These options will only be utilized if the query is for a rate calculation and if the "counter" options is set to true. @since 2.0
