Android Device - Attach to Process Target Type

Process name field

Identify the executable to analyze by its name.

PID field

Identify the executable to analyze by its process ID (PID).

Click the Select button to see a list of currently available processes to attach to. As soon as you select a process of interest, the VTune Amplifier automatically populates the Process name and PID fields with the data for the selected process.

Automatically resume collection after (sec)

Specify the time that should elapse before the data collection is resumed. When this options is used, the collection starts in the paused mode automatically.

Automatically stop collection after (sec)

Set the duration of data collection in seconds starting from the target run. This is useful if you want to exclude some post-processing activities from the analysis results.

Managed code profiling mode menu

Select a profiling mode for managed code. Managed mode attributes data to managed source and only collects managed portion. Native mode collects everything but does not attribute data to managed source. Mixed mode collects everything and attributes data to managed source where appropriate.

Analyze unplugged device check box

Enable collection on an unplugged device to exclude ADB connection and power supply impact on the results. When this option is used, you configure and launch an analysis from the host but data collection starts after disconnecting the device from the USB cable or a network. Collection results are automatically transferred to the host as soon as you plug in the device back.

Duration time estimate menu (deprecated)

Estimate the application duration time. This value affects the size of collected data. For long running targets, sampling interval is increased to reduce the result size. For hardware event-based sampling analysis types, the VTune Amplifier uses this estimate to apply a multiplier to the configured sample after value.

Analyze system-wide check box

Enable analyzing all processes running on the system. When disabled, only the target process is analyzed. This option is applicable to hardware event-based sampling analysis types only.

Limit collected data by section

If the amount of raw collected data is very large and takes long to process, use any of the following options to limit the collected data size:

• Result size from collection start, MB: Set the maximum possible result size (in MB) to collect. VTune Amplifier will start collecting data from the beginning of the target execution and suspend data collection when the specified limit for the result size is reached. For unlimited data size, specify 0.

• Time from collection end, sec: Set the timer enabling the analysis only for the last seconds before the target run or collection is terminated. For example, if you specified 2 seconds as a time limit, the VTune Amplifier starts the data collection from the very beginning but saves the collected data only for the last 2 seconds before you terminate the collection.

CPU mask

Specify CPU(s) to collect data on (for example: 2-8,10,12-14). This option is applicable to hardware event-based analysis types only.

Custom collector

Provide a command line for launching an external collection tool, if any. You can later import the custom collection data (time intervals and counters) in a CSV format to a VTune Amplifier result. Click the Modify button to add a path to your external collector.

Result location options

Select where you want to store your result file. By default, the result is stored in the project directory.
