High watermark in dashboard charts
Every chart in the Dashboard Chart Work Area section shows a high water mark. The high water
mark is an indication of the maximum average usage value of that resource in the past 24 hours.
High watermark is displayed after considering the usage data of a resource in the last 24 hours for
a selected metric.
IMPORTANT:
• High watermark is applicable only for resources belonging to Frontend, Cache and Backend cat-
egories. It is not applicable for LDEVs.
• High watermark is displayed for only one resource and metric combination. It is disabled if you
choose multiple resources and metrics.
