show performance cache_partition

show performance cache_partition


The show performance cache_partition command is used to query performance statistics on a cache partition.


show performance cache_partition cache_partition_id=?

show performance cache_partition cache_partition_id_list=?





cache_partition_id=? ID of a cache partition on which you want to query performance statistics.

To obtain the value, run "show cache_partition general".

cache_partition_id_list=? List of cache partition IDs on which you want to query performance statistics.
  • To obtain the value, run "show cache_partition general". When multiple cache_partitions need to be added, separate these cache_partition IDs with commas (,), or ID range separated by hyphens (-), such as: 0,5-8.
  • A maximum of 50 IDs can be queried.



Usage Guidelines

  • You will be prompted with optional performance statistics categories upon running this command. In this condition, typing a number or multiple numbers (separated by commas) for the selected categories and pressing "Enter" displays the performance statistics for those categories.
  • Performance statistics will be updated in real time.
  • Typing "q" on the command line interface (CLI) exits the active performance statistics display.
