system show performance output

Hi there ...

My customer wants to get Max duration for system show performance throughput result keeping 10min interval .

I found DDOS 5.7 allow to do so ... see below

sysadmin@dd140-1# system show performance custom-view throughput duration 300 hrs

------------------------------------------------------------

Time Stamp    |Throughput

              |read    write repl network   repl pre-comp

Date   Time |                    in/out         in/out

MM/DD/YY HH:MM| MB/s    MB/s MB/s           MB/s

-------- ----- ------- ------- -------------- --------------

11/12/17 00:46     0.0 0.0      0.0/  0.0 0.0/  0.0

..........

11/22/17 03:29     0.0 0.0      0.0/  0.0 0.0/  0.0

But in 6.0 . 143 line is the max output for the result ... ( that is why information is cut off between )

sysadmin@dd670-1# system show performance custom-view throughput duration 300 hrs

----------------------------------------------------

Time Stamp         |Throughput                     |

                   |read   write repl-in  repl-out|

Date       Time |                               |

YYYY-MM-DD HH:MM:SS|MiB/s  MiB/s MiB/s     MiB/s|

----------------------------------------------------

2017-11-09 17:00:00   0.0 0.0     0.00      0.00

......

2017-11-14 16:40:00   0.0 0.0     0.00      0.00

Can anybody have better Idea to get MAX result for system show performance output ? in 6.0 ?

thanks !
