Data Collection and Display
To display system information from a target device in the Remote Kernel Tracker tool, you must first connect to the target device with Platform Manager. For more information about connecting to a target device with Platform Manager, see Application Connectivity.
The tool collects and displays data in three distinct modes.
The following table shows the data collection modes for Remote Kernel Tracker and a description of each mode.
| Mode | Description |
|---|---|
| Data collection | Collects data and updates the UI in real time. This mode is the default mode for Remote Kernel Tracker. This mode allows you to monitor system events as they happen. To observe the initial boot sequence of the OS, launch the tool before you download the OS image. In this mode, the amount of data collected is limited only by the amount of system memory on your desktop computer. |
| Limited buffer | Allows you to specifically limit the quantity of data stored by Remote Kernel Tracker by defining the buffer size. Otherwise, this mode is the same as data collection mode. When the amount of data stored within the buffer reaches the predefined limit, the newest events begin to replace the oldest events. The size of the buffer may range from 1 megabyte (MB) to 100 MB. This mode is useful when running stress tests or engaging in other tasks that generate a large amount of data because the tool's performance diminishes as the amount of data in its buffer increases. |
| File | Allows you to view data from a Windows CE System Log (.clg) file. You may create a .clg file after you collect data in data collection mode or limited buffer mode. The .clg file records all data collected during Remote Kernel Tracker session. |
Remote Kernel Tracker runs in data collection or limited buffer mode without additional configuration. Without additional configuration, the tool does not record data during boot time and does not collect interrupts, translation look-aside buffer (TLB) misses, or kernel calls. For more information about collecting data during boot time, see Configuring Remote Kernel Tracker to Collect Data During Boot Time. For more information about collecting all types of data, see Configuring Remote Kernel Tracker to Collect All Types of Data.
Note Remote Kernel Tracker does not display interrupts for a release OS unless you enable profiling before building the OS.
In both data collection mode and limited buffer mode, you can view activity on the target device in real time. For more information, see Viewing Events While They Occur.
You can modify the data that Remote Kernel Tracker collects by configuring collection zones. For more information about collection zones, see Debug Zones and Debug Zones Dialog Box.
