Abstract

System performance data and program performance data may be collected, converted into the same format and correlated by time. A graph or other display of system performance data over a time period may be displayed. A bar may be superimposed on the graph. A corresponding grid or other display, of program performance data over the same time period may be displayed. An item or line of the grid corresponding to a program event at a particular timepoint may be selected. A timepoint in the system performance graph may be selected by adjusting the position of the bar superimposed on the system performance graph. In response to the movement of the bar, the portion of the grid of program performance data displayed may be changed so that the grid of program performance data displays program performance data corresponding to the selected timepoint in the system performance graph.

Claims

1. A system for correlating system performance data and program performance data comprising:

a profiler that receives the system performance data and the program performance data, converts the system performance data and the program performance data into a common format and generates from the converted system performance data and the converted program performance data a correlation table;

a user interface for displaying information associated with the plurality of data elements of the correlation table.

2. The system of claim 1, wherein in response to receiving a second point in time associated with the system performance data, the user interface displays a one of the plurality of data elements in a highlighted display, the one data element associated with the second point in time and the program performance data source.

3. The system of claim 1, wherein in response to receiving a second point in time associated with the program performance data, the user interface displays a vertical line superimposed over a one of the plurality of data elements associated with the second point in time and the system performance data source.

4. The system of claim 1, wherein the system performance data is displayed as a graph.

5. The system of claim 1, wherein the program performance data is displayed as a grid, the grid comprising a plurality of items, each of the plurality of items comprising the point in time and an event occurring at the point in time.

6. The system of claim 4, wherein a second point in time is selected by moving a vertical line superimposed on the graph.

7. The system of claim 5, wherein a second point in time is selected by selecting a one of the plurality of items.

8. The system of claim 1, further comprising a system performance data definition file, the system performance data definition file describing a column of data representing a system counter over a time interval.

9. The system of claim 1, further comprising a program performance data definition file, the program performance data definition file describing a plurality of types of information collected by a program monitoring module.

10. The system of claim 1, wherein the profiler comprises a reader for reading system performance data.

11. The system of claim 1, wherein the profiler comprises a reader for reading program performance data.
