PerfettoTracePostProcessor

public class PerfettoTracePostProcessor
extends BasePostProcessor

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

A post processor which retrieves perfetto trace files from the test logs and runs the trace processor on them to produce a perfetto metric proto.

Summary

Public constructors

PerfettoTracePostProcessor()

Public methods

processRunMetricsAndLogs( rawMetrics, runLogs)

Implement this method in order to generate a set of new metrics from the existing metrics and logs.

processTestMetricsAndLogs(TestDescription testDescription, testMetrics, testLogs)

Implement this method to post process metrics and logs from each test.

Protected methods

MetricMeasurement.DataType getMetricType()

Set the metric type to RAW so that metrics will be processed by subsequent post processors.

Public methods

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.

Protected methods

getMetricType

protected MetricMeasurement.DataType getMetricType ()

Set the metric type to RAW so that metrics will be processed by subsequent post processors.

This is necessary for MetricFilePostProcessor to write the metrics to the results file.

Returns
MetricMeasurement.DataType
