Intel® VTune™ Amplifier XE and Intel® VTune™ Amplifier for Systems Help
Use this configuration to specify a particular process to attach to and analyze with the Intel® VTune™ Amplifier for Systems on a target Android* system via ADB connection.
When you run an analysis, the VTune Amplifier attaches to the process and starts collecting data. To detach from the process, click the button on the command toolbar. The process will keep running but the analysis will be stopped.
To access the configuration, open the Analysis Target window, choose the Android (ADB) target system on the left, select the Attach to Process target type from the drop-down menu on the right and in the via ADB on device drop-down menu select your Android device.

To Do This |
---|---|
Process name field |
Identify the executable to analyze by its name. |
PID field |
Identify the executable to analyze by its process ID (PID). To see a list of available processes, click the Browse button and select the required package in the Select Process dialog box. |
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. |
Use the Advanced section to provide more details on your target configuration.

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 |
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:
NoteThe size of data stored in the result directory may not exactly match the specified result size due to the following reasons:
|
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. |
Click the Choose Analysis button on the right to switch to the Analysis Type tab for selecting, configuring, and launching an analysis. The Analysis Type tab displays analysis types applicable to the specified target type.
You can launch an analysis only for an accessible target. For an arbitrary target, you can only generate a command line configuration, save it to the buffer and later launch it on the intended host.
