Monitor
The Monitor function provides an at-a-glance view of the health and performance of cluster nodes,
and the ability to analyze historical data and real time trends. LUN monitoring provides container
level statistics both on a per-node basis, as well as aggregated. Target monitoring provides port level
statistics. You can perform the following tasks from the Monitor function pages:
Overview
The Overview function provides a high-level view of real-time or historical data. You can
customize how you view the data, choosing between line and area graphs, time trends, as well as
the type of metrics used to formulate the data. You also have the option to view data for a container,
LUN, or port.
• Real Time Performance Trend—Shows the last five minutes of performance trends for the
selected metric. New real time values are appended into the graph every ten seconds.
• Current Value—Shows real time data at this time. The graph time is listed at the bottom of the
panel.
Customizing the Output Display
The following task demonstrates how to customize the data display to suite your needs. You can
