Add support for dimension, and link with condition and added DurationMetric
Now we support following metrics:
<Duration> of [app holding a wake lock], while [*this app*] is [in background] [AND] [screen is off]
[Slice] the output by [app name, wake lock name], with bucket size [30sec]
+ Also added onDumpReport() api in MetricsManager, it can be called from client to fetch the data from
statsd
+ Also added command line tool to dump the StatsLogReport from all metrics for debugging.
+ Synced proto from google3. with a pending cl (cr/172359050)
TODO: We need to add tons of tests to test the Metrics. I will work on it after this CL so people
can be unblocked.
I locally test the duration metric with wake lock with an app that generates StatsLog events.
Test: statsd_test
and manual test, and run:
adb shell cmd stats dump-report
We have a default config, which contains a metrics to count PROCESS_START event sliced by
package name.
