Figure 4.15: Procedure of problem analysis process of LTTng and KAS<br />
Figure 4.15 is the illustr<strong>at</strong>ing process flow of before and after KAS. Normally, LTTng does<br />
event logging and after th<strong>at</strong> analyze event logs by Linux Toolkit Viewer (LTTV). However,<br />
the proposed system analyzes KAS after event logging. Wh<strong>at</strong>ever analysis is done using<br />
LTTV or KAS, the problem analyzed lastly by a developer and an administr<strong>at</strong>or. Therefore,
