Performance overview
Performance monitoring provides details about the quantity of traffic and errors a specific port or
device generates on the fabric over a specific time frame. You can also use performance to indicate
the devices that create the most traffic and to identify the ports that are most congested.
Performance allows you to monitor your SAN by gathering and displaying real-time performance
data (FC and GE ports as well as FCIP tunnels).
Performance measures
Performance measures enable you to select one or more measures to define the graph or report.
The measures available to you depend on the object type from which you want to gather
performance data.
