P9000 Performance Advisor plots the appropriate graphs in the Chart Work Area. The duration
for which the data points are plotted in the chart depends on the threshold duration specified on
the Threshold Settings screen. By default, the graphs are plotted for data points collected in the
last 6 hours of the management station's time.

If you are plotting the port I/O metrics for a P9000 disk array, the port type is also displayed
beside the port ID in the chart legends.
After the graphs are plotted, use the chart options in the Chart Work Area to perform additional
activities on charts. For more information on using the chart options, see “Plotting charts” on page 264.
High watermark in dashboard charts
Every chart in the Dashboard Chart Work Area section displays a high watermark. The high watermark
is an indication of the maximum average usage value of that component in the past 24 hours. High
watermark is displayed after considering the usage data of a component in the last 24 hours for a
selected metric.
IMPORTANT:
• High watermark is applicable only for components in the Frontend, Cache, Backend, and MP Blade
categories. It is not applicable for LDEVs.
• High watermark is displayed for only one component and metric combination. It is disabled if
you choose multiple components and metrics.
