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.
