Using the command line interface

You can use the HP P6000 Performance Data Collector command line interface to display array performance data in a tabular format. The procedures in this section assume you are familiar with command line interfaces.

Viewing arrays

To view arrays that are visible to HP P6000 Performance Data Collector:

1.Launch HP P6000 Performance Data Collector from the desktop icon.

2.Enter the following command: evaperf ls

The visible arrays are listed.

Specifying the output

This section describes the ways you can specify the command line interface output.

Refreshing data

The command line interface output does not refresh automatically while you are viewing it.

To continuously refresh the array data, enter the following command:

evaperf as -cont

To set a refresh frequency (in seconds), include the n modifier in the command:

evaperf as -cont 10

If you do not specify an interval or you provide an invalid polling frequency argument, the default interval of one second is set.

IMPORTANT: If a controller reboot occurs, the connection to the HP P6000 Performance Data Collector service from HP P6000 Performance Data Collector client needs to be reestablished.

Limiting data quantity

You can limit the amount of data that is collected and presented, which can be useful if your configuration includes numerous arrays, physical disks, and virtual disks.

To limit the arrays for which HP P6000 Performance Data Collector collects data, enter the following command:

evaperf as -sz array1 array10 array32

The output contains data only for the specified arrays.

To limit the virtual disks for which HP P6000 Performance Data Collector collects data, enter the following command:

evaperf vd -fvd disk2 disk4 disk8

The output contains data only for the specified virtual disks.
