Table 7 HP P6000 Performance Data Collector command modifiers (continued)

Description

Modifier

Displays the WWNs, GroupId, DRMGroupId, and HostName along with their
corresponding friendly names. If friendly names are not configured a No FN message
is displayed in place of the friendly name.

-fnid

Copies output to a file as well as displaying it in the command prompt. You can combine
this modifier with -cont and -dur for a fixed-time data capture. For example, if you

-fo

filename

enter evaperf vd -cont 5 -dur 30 -fo capture.log, virtual disk data is
displayed in CSV at five second intervals for a total of 30 seconds and is also written to
the capture.log file.

Limits virtual disk data collection to the specified virtual disks. You must enter at least one
virtual disk. You can also combine this modifier with -sz to limit data collection to the

-fvdvdisk [vdisk]*

specified storage systems. For example, if you enter evaperf vd -fvd test1 test2
-sz server1

, data is collected for virtual disks test1 and test2 on array server1. You

can use this modifier with the vd, vdrl, vdwl, and vdts commands.

Displays output data in kilobytes per second (1,024). The default is megabytes per
second (1,000,000).

-KB

Specifies that friendly names should not be used.

-nfn

Specifies that no headings be included in CSV output.

-nh

Specifies that a time stamp not be included in the CSV output.

-nots

Specifies the directory in which the output files from the mof command are saved.

-od

Limits array data collection to the specified storage systems. You must enter at least one
storage system and you can use this modifier with any command. When specifying

-szarray [array]*

storage systems, you can use either the storage system WWN or friendly name. For
example, if you enter evaperf as -sz server1 server3, data is displayed for
arrays server1 and server3 only. If you do not include this modifier, data is collected
from all storage systems visible to the host.

Displays TLC-compliant data for the mof command.

-tlc

Displays output in tab-separated variable (TSV) format with a time stamp.

-tsv

Adds a time stamp to the -csv output in the following format: Fri Jul 23 16:23:05
2004

.

–ts1

Adds a time stamp to the -csv output in the following format: 23/Jul/2004 16:23:05
2004

. This is the default format.

-ts2

Display times in microseconds (the default is milliseconds). Latencies are displayed in
milliseconds (ms) by default. Use the -us option to show times in microseconds for more
accuracy.

The -us modifier does not affect the following commands:

-us

vdrl

vdrlg

vdwl

vdwlg

Using the graphical user interface

This section describes how to display and manage storage system performance metrics using the
graphical user interface, Windows Performance Monitor, and assumes that you are familiar with
the tool.

Windows Performance Monitor does not permit more than one hierarchical object level. Therefore,
objects, such as virtual disks, are grouped as a single list of instances, even though they may be
