| Usage: launch_application package activity | parse_metrics --package <name> --timestamp <timestamp> [OPTIONS]... |
| |
| Reads from stdin the result of 'am start' metrics. May also parse logcat |
| for additional metrics. |
| |
| Output form: |
| |
| MetricName_unit=numeric_value |
| MetricName2_unit=numeric_value2 |
| |
| This may block until all desired metrics are parsed from logcat. |
| To get a list of metrics without doing real parsing, use --simulate. |
| |
| To add package-specific metrics, add a script called 'metrics/\$full_package_name' |
| that exposes additional metrics in same way as above. |
| |
| (required) |
| -p, --package <name> package of the app that is being used |
| -ts, --timestamp <name> logcat timestamp [only looks at logcat entries after this timestamp]. |
| |
| (optional) |
| -s, --simulate prints dummy values instead of real metrics |
| -a, --activity <name> activity to use (default: inferred) |
| -h, --help usage information (this) |
| -v, --verbose enable extra verbose printing |
| -t, --timeout <sec> how many seconds to timeout when trying to wait for logcat to change |
| EOF |
