Splits 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, P9000Watch will 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 P9000Watch to collect performance data. The program
terminates once this time limit is reached.

Ports: 1-50 LDEVs: 1-50
RAID groups: 1-50 host
groups: 1-50
Ports: 10 LDEVs: 10
RAID groups: 10
host groups: 10
Enables you to specify the volume of data to be displayed in the
output screen for ports, LDEVs, RAID groups, and host groups.
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.
Real-Time Monit-
or Size
5 - 300 seconds10 seconds
Enables 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
P9000Watch in the CLI mode, the screen is refreshed every
5 seconds.
