Chapter 3 Operations of Performance Monitoring Function
In "Figure 3-28 Example of Creating a Graph", some points are not linked by lines. The graph making tool
(Storage Performance Report Viewer) does not link points with lines when statistic information is no longer
continuous in order to accurately express the continuity of the statistic information in the graph. The statistic
information loses its continuity in the following cases:
Configuration of the disk array was changed during the monitoring of performance.
A fault occurred in the disk array during the monitoring of the performance and the monitoring of the disk
array performance could not be continued.
A user terminated the accumulation of statistic information due to the specification during the monitoring of
performance.
If log accumulation interval is adjusted automatically (for giving a higher priority to file input/output from a
business host), the intervals between the points increase in accordance with the adjusted time interval.
(3) Editing with spreadsheet software
The statistic information history files extracted with header options specified can be used on spreadsheet software,
such as Microsoft Excel2000. On the software, sorting the output values makes it easier to identify the values.
Figure 3-29 shows an example of editing a statistic information history file extracted with header option specified
(CSV file), using Microsoft Excel2000.
