1-168 hours24 hoursSplits the data according to the time intervals (in hours) and stores
them in different .csv files. This is used when large amount of
data is collected.
For example: If you have selected the Data Split Time as 1 and
the Data Collection Time Limit as 12, HP XP P9000Watch will
Data Split Time
create 12 new files, each containing performance data for an
hour’s time.
NOTE: The data splitting activity is performed for the duration
set in the Data Collection Time Limit.
In the Interactive mode, if you enter a value greater than 24 hours,
then the .csv files might grow to a large size. So, preferably
the value of the Data Split Time should be given as 1 hour.

Enables you to specify the duration in hours and minutes for which
you want HP XP P9000Watch to collect performance data. The
program terminates once this time limit is reached.

Enables you to specify the volume of data to be displayed in the
output screen for ports, LDEVs, RAID groups, and host groups.
In case of Sync/Async metrics, you can set the number of
PVOL/SVOLs, RAID Groups, CLPRs and Replication Ports. In case

For example, by default the Output screen displays 10 most active
ports, 10 most active LDEVs, 10 most active RAID groups, and
10 most active host groups.

5 - 300 seconds10 secondsEnables you to specify the frequency at which the screen updates/
refreshes the performance collection data obtained from a disk
array.
NOTE: By default, the collection update interval is 10 seconds
in the Interactive and CLI modes, where the screen is refreshed
every 10 seconds. You can change this collection update interval
time from 5 to 300 seconds in the Interactive mode. The new
collection update interval is automatically used in the CLI mode
also.
For example, if the user changes the collection update interval
time to 5 seconds in the Interactive mode and then runs the HP
XP P9000Watch in the CLI mode, the screen is refreshed every
5 seconds.

data of a disk array should be archived in the .csv file.
Archival
Frequency
NOTE: By default, the archival frequency is 10 seconds in the
Interactive and CLI modes, where the data is archived every 10
seconds. You can specify a minimum of 5 seconds or a maximum
of 300 seconds as the archival frequency. The new archival
frequency is automatically used in the CLI mode also, if –a option
is not specified.
For example, if you change the archival frequency to 5 seconds
in the Interactive mode and then run the HP XP P9000Watch in
the CLI mode without specifying –a option, the performance data
is archived in the .csv file every 5 seconds.
