AggregatePostProcessor

public class AggregatePostProcessor
extends BasePostProcessor

java.lang.Object
   ↳ com.android.tradefed.postprocessor.BasePostProcessor
     ↳ com.android.tradefed.postprocessor.AggregatePostProcessor

A metric aggregator that gives the min, max, mean, variance, standard deviation, total, count and optionally percentiles for numeric metrics collected during multiple-iteration test runs, treating them as doubles. Non-numeric metrics are ignored. Metrics that have a mix of numeric and non-numeric values will also be ignored.

Note that count will only be present if a metric has all-numeric values; otherwise, it will be absent along with all the other stats.

It parses metrics from single string as currently metrics are passed this way.

Public methods

processRunMetricsAndLogs( rawMetrics, runLogs)

processRunMetricsAndLogs

public  processRunMetricsAndLogs ( rawMetrics, 
                 runLogs)

Implement this method in order to generate a set of new metrics from the existing metrics and logs. Only the newly generated metrics should be returned, and with unique key name (no collision with existing keys are allowed).

Parameters
rawMetrics : The set of raw metrics available for the run.
runLogs : The set of log files for the test run.
Returns
The set of newly generated metrics from the run metrics.

processTestMetricsAndLogs

public  processTestMetricsAndLogs (TestDescription testDescription, 
                 testMetrics, 
                 testLogs)

Implement this method to post process metrics and logs from each test. Only the newly generated metrics should be returned, and with unique key name (no collision with existing keys are allowed).

Parameters
testDescription TestDescription: The TestDescription object describing the test.
testMetrics : The set of metrics from the test.
testLogs : The set of files logged during the test.
Returns
The set of newly generated metrics from the test metrics.
