Table 6 HP P6000 Performance Data Collector commands (continued)

Command	Description
vdrlg [lunwwn]	Graphs virtual disk read latency histograms for all LUNs or a specific WWN. This
	command is available on the HSV200 series of controllers onward.
vdwl	Displays virtual disk write latency histograms. This command is available on the HSV200
	series of controllers onward.
vdwlg [lunwwn]	Graphs virtual disk write latency histograms for all LUNS or a specific WWN. This
	command is available on the HSV200 series of controllers onward.
vpw	Verifies array passwords for use with HP P6000 Performance Data Collector.
verifycvconfig	Verifies whether HP P6000 Command View is accessible for state data collection.

Command modifiers

Table 7 (page 84) lists the modifiers you can use in the command line interface. Modifiers must be preceded by a minus sign (–). The modifiers are listed alphabetically.

When using Time Line Vizualizer (TLViz), only the -cont, -csv, -dur, and -ts2command modifiers are supported.

Table 7 HP P6000 Performance Data Collector command modifiers

Modifier	Description
-cn	Substitutes contractions from the fnames.dict file.
-contn	Runs an HP P6000 Performance Data Collector command continuously. You can specify
	the interval by adding a number (n). Otherwise, the default interval is one second. Press
	Ctrl+C to exit from this mode.
-csv	Displays data in comma-separated value (CSV) format and automatically includes a
	timestamp. The timestamp format can be modified using the -ts1or -ts2modifiers.
-durn	Specifies the duration of a continuous mode session. For example, if you enter evaperf
	vd -csv-cont-dur 30, virtual disk data is displayed in CSV format at one second
	intervals for a total of 30 seconds.
-fdkeyword	Displays data that contains the specified keywords. You must enter at least one keyword.
	To enter multiple keywords, separate each keyword with a space. For example, if you
	enter evaperf vd -fd test preliminary good, the data that displays contains
	the words test, preliminary, and good.
-fnid	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.
-fofilename	Copies output to a file as well as displaying it in the command prompt. You can combine
	this modifier with -contand -durfor a fixed-time data capture. For example, if you
	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.
-fvdvdisk [vdisk]*	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 -szto limit data collection to the
	specified array(s). 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.
-KB	Displays output data in kilobytes per second (1,024). The default is megabytes per
	second (1,000,000).
-nfn	Specifies that friendly names should not be used.
-nh	Specifies that no headings be included in CSV output.
