  1. Flash Cache ヒット率を表示するには、次のコマンドを使用します。

例:

::*> statistics start -sample-id test -object ext_cache_obj -counter inserts|hit_percent
Statistics collection is being started for sample-id: test

::*> statistics stop -sample-id test
Statistics collection is being stopped for sample-id: test

::*> statistics show -sample-id test

Object: ext_cache_obj
Instance: ec0
Start-time: 12/7/2021 22:11:25
End-time: 12/7/2021 22:11:45
Elapsed-time: 20s
Scope: fas8200-dal-1a

   Counter                            Value
   -------------------------------- --------------------------------
   hit_percent                           0%
   inserts                              0

Object: ext_cache_obj
Instance: ec0
Start-time: 12/7/2021 22:11:25
End-time: 12/7/2021 22:11:45
Elapsed-time: 20s
Scope: fas8200-dal-1b

   Counter                            Value
   -------------------------------- --------------------------------
   hit_percent                           0%
   inserts                              0
4 entries were displayed.

 

2. Flash Cache のパフォーマンスデータを一定の間隔で継続的に表示するには、次のコマンドを使用します。

例:

::*> statistics show-periodic -object ext_cache_obj -instance ec0 -interval 2 -iterations 5 -counter inserts|hit_percent
fas8200-2n-dal-1: ext_cache_obj.ec0: 12/7/2021 22:00:08
   hit   Complete   Number of
 percent  inserts Aggregation Constituents
 ------- -------- ----------- ------------
    0%     0    n/a    n/a
    0%     0    n/a    n/a
    0%     0    n/a    n/a
    0%     0    n/a    n/a
    0%     0    n/a    n/a
fas8200-2n-dal-1: ext_cache_obj.ec0: 12/7/2021 22:00:18
   hit   Complete   Number of
 percent  inserts Aggregation Constituents
 ------- -------- ----------- ------------
Minimums:
    0%     0     -     -
Averages for 5 samples:
    0%     0     -     -
Maximums:
    0%     0     -     -
