To display system information from a target device in the Kernel Tracker tool, you must first connect to the target device.
The tool collects and displays data in the following modes.
| Mode | Description |
|---|---|
Data Collection |
Collects data and updates the UI in real time. This mode is the default mode for 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 run-time 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 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 can range from 1 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 Embedded CE System Log (.clg) file. You can 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. |
By default, the Kernel Tracker 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 Kernel Tracker to Collect Data During Boot Time.
For more information about collecting all types of data, see Configuring Kernel Tracker to Collect All Types of Data.
Note
Kernel Tracker does not display interrupts for a run-time image built from the default Release configuration unless you enable profiling before building the run-time image.
In 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 Kernel Tracker collects by configuring collection zones. For more information about collection zones, see Debug Zones.
