Event data from different parts of a system might be found recorded in event logs. Often the individual logs only show a small part of the system, but by correlating different sources into a consistent context it will be possible to gain further information and a wider view. This would facilitate in finding source of errors or certain behaviors within the system. This thesis will present the correlation possibilities between event data from different layers of the Ericsson Connectivity Packet Platform (CPP). This was done first by developing and using a test base application for the OSE operating system through which the event data can be recorded for the same test cases. The log files containing the event data have been studied and results will be presented regarding format, structure and content. For reading and storing the event data, suggestions of interpreters and data models are also provided. Finally a prototype application will be presented, which will provide the defined interpreters, data models and a graphical user interface to represent the event data and event data correlations. The programming was conducted using Java and the application is implemented as an Eclipse Plug-in. With the help of the application the user will get a better overview and a more intuitive way of working with the event data. |
