Command modifiers
Table 7 (page 84) lists the modifiers you can use in the command line interface. Modifiers must

Table 7 HP P6000 Performance Data Collector command modifiers
DescriptionModifier
Substitutes contractions from the fnames.dict file.-cn
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.
-contn
Displays data in comma-separated value (CSV) format and automatically includes a
timestamp. The timestamp format can be modified using the -ts1 or -ts2 modifiers.
-csv
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.
-durn
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
-fdkeyword
enter evaperf vd -fd test preliminary good, the data that displays contains
the words test, preliminary, and good.
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
-fofilename
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 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.
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
