Abstract
A novel apparatus and method for analyzing and displaying the operation of a computer is provided, that can display a timing chart with which the relationship between transmission processes and reception processes, each relating to inter-process communications, can be easily grasped. The apparatus includes a measuring device for measuring and collecting as chronological event trace data a software event occurring within a computer to be measured, an analyzer for analyzing the operation of the computer based on the event trace data collected by the measuring device, and a display for manifesting the operation of the computer analyzed by the analyzer.
Claims7
An apparatus for analyzing and displaying an operation of a computer, comprising:
- measuring means for measuring and collecting as chronological event trace data a software event occurring within a computer to be measured;
- analyzing means for analyzing the operation of said computer based on the event trace data collected by said measuring means;
- and
- display means for manifesting the operation of said computer analyzed by said analyzing means;
- said measuring means detecting both a first event of changing processes on said computer and a second event of performing inter-process communications and then collecting said first and second events as chronological information;
- said analyzing means creating data displaying a process operation, said data representing a run period and a non-run period of each process, from said first event, and creating inter-process communications data from said second event, said inter-process communications data being formed of a pair of a transmission process and a transmission time and a pair of a reception process and a reception time in inter-process communications;
- said display means manifesting the run period and the non-run period of each process in a chronological order and manifesting, in one-to-one correspondence, a point represented with a transmission process and a transmission time and a point represented with a reception process and a reception time in each inter-process communications.
