10 Monitoring array performance using HP P6000
Performance Data Collector
With HP P6000 Command View server-based management, you can use HP P6000 Performance
Data Collector (formerly HP Command View EVAPerf) to monitor and display array performance
metrics from a command line interface or a graphical user interface. HP P6000 Performance Data
Collector is not directly available on array-based management; however, HP P6000 Performance
Data Collector can be installed on a host or server with an Fibre Channel connection to the array.
This allows you to monitor performance with array-based management. You can also view
performance metrics in an external application, such as Microsoft Excel, after you export data to
either a comma-separated value (CSV) or tab-separated value (TSV) format.
HP P6000 Performance Data Collector can use any available path to retrieve metrics. However,
when used with VMware ESX 3.5, metrics are provided for one controller only.
You can monitor and display the following metrics:
• Arrays
• Array controllers
• Disk group information
• DR groups
• DR tunnels
• Host connections
• Host port statistics
• Physical disks
• Port status
• Virtual disks
IMPORTANT: For UAC-enabled systems, when you install or run HP P6000 Performance Data
Collector, you must use the Run As Administrator option.
