1.3 Contribution
When developing a project, there are a variety of SDK and various debugging methods [12]
[23] [38] [40]. However, while developing embedded systems, developers should solve
problems by using limited tools and debugging methods [36]. Debugging and performance
tuning [41] [56] are an important part in the system development. The system developer for
debugging and performance tuning needs error messages that generated by file system
errors, network errors [34], hard drive errors, and memory errors in the systems. In addition,
it is important to catch where the problem happened and what it is. The proposed system
using the event log is the following contributions.
� Among the huge event logs, we can find the problem easily.
� Separating the error data from whole data and we can analyze only the error data.
� Analyzing the event logs, we can analyze the cause of the problem.
We would like to suggest solutions to solve the problems in the kernel and to improve
performance by finding and analyzing problems effectively.
1.4 Outline
