text: **Real-time performance monitoring**
  
  IBM Storwize V7000 supports real-time performance monitoring. Real-time performance 
  statistics provide short-term status information for the Storwize V7000. The statistics are 
  shown as graphs in the management GUI, or can be viewed from the CLI. 
  
  With system-level statistics, you can quickly view the CPU usage and the bandwidth of 
  volumes, interfaces, and MDisks. Each graph displays the current bandwidth in megabytes 
  per second (MBps) or I/Os operations per second (IOPS), and a view of bandwidth over time. 
  
  Each node collects various performance statistics (mostly at 5-second intervals) and the 
  statistics that are available from the config node in a clustered environment. This information 
  can help you determine the performance effect of a specific node.
