Display running instances

Availability: This command is available to cluster administrators at the advanced privilege level.

Description

The automated-working-set-analyzer show command displays the Automated Working-set Analyzer running instances.

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-node <nodename>] - Node Name

This parameter indicates the node name that the AWA instance runs on.

[-flash-cache {true|false}] - Flash Cache Node-wide Modeling

This parameter indicates whether the AWA is modeling flash-cache.

[-aggregate-uuid <UUID>] - Uuid of the Aggregate

This parameter indicates the aggregate uuid that the AWA instance runs on.

[-aggregate <aggregate name>] - Aggregate

This parameter indicates the aggregate name that the AWA instance runs on.

[-working-set-size {true|false}] - Working Set Size

This parameter indicates whether the AWA instance is configured to find the working set size.

[-start-time <Date>] - Starting Time

This parameter indicates the time when the AWA instance was started.

[-total-intervals <integer>] - Total Interval Count

This parameter indicates the total number of intervals that the AWA instance has covered.

[-read-throughput {<integer>[Bps|KBps|MBps|GBps]}] - Read Throughput

This parameter indicates the maximum read throughput over an interval that AWA has observed from the storage disks.

[-write-throughput {<integer>[Bps|KBps|MBps|GBps]}] - Write Throughput

This parameter indicates the maximum write throughput over an interval that AWA has observed to the storage disks

[-cacheable-read <percent>] - Cacheable Read

This parameter indicates the maximum percent of cacheable read over an interval that AWA has observed. Cacheable reads are non-sequential reads, i.e., the percentage of data reads that could have been cached.

[-cacheable-write <percent>] - Cacheable Write

This parameter indicates the maximum percent of cacheable write over an interval that AWA has observed. Cacheable writes are random overwrites, percentage of disk writes that could have been cached.

[-projected-cache-size {<integer>[KB|MB|GB|TB|PB]}] - Max Projected Cache Size

This parameter indicates the projected Flash Pool cache usage.

[-projected-read-hit <percent>] - Projected Read Hit

This parameter indicates the percentage of blocks that could be read from the Flash Pool cache instead of HDDs.

[-projected-write-hit <percent>] - Projected Write Hit

This parameter indicates the percentage of block overwrites that could go to the Flash Pool cache instead of HDDs.

[-referenced-interval-id <integer>] - Referenced Interval ID

This parameter indicates the interval in which the cache size effect information is derived from.

[-referenced-interval-time <Date>] - Referenced Interval Time

This parameter indicates the time when the referenced interval for the cache size effect information is derived from.

[-referenced-interval-cache-size {<integer>[KB|MB|GB|TB|PB]}] - Referenced Interval Cache Size

This parameter indicates the cache size at the end of the referenced interval from which the cache size effect information is based on.

[-read-hit-20 <percent>] - 20% Cache Read Hit

This parameter indicates the predicted read hit rate when the cache size is 20% of the referenced cache size.

[-read-hit-40 <percent>] - 40% Cache Read Hit

This parameter indicates the predicted read hit rate when the cache size is 40% of the referenced cache size.

[-read-hit-60 <percent>] - 60% Cache Read Hit

This parameter indicates the predicted read hit rate when the cache size is 60% of the referenced cache size.

[-read-hit-80 <percent>] - 80% Cache Read Hit

This parameter indicates the predicted read hit rate when the cache size is 80% of the referenced cache size.

[-read-hit-100 <percent>] - 100% Cache Read Hit

This parameter indicates the predicted read hit rate when the cache size is 100% of the referenced cache size.

[-write-hit-20 <percent>] - 20% Cache Write Hit

This parameter indicates the predicted write hit rate when the cache size is 20% of the referenced cache size.

[-write-hit-40 <percent>] - 40% Cache Write Hit

This parameter indicates the predicted writehit rate when the cache size is 40% of the referenced cache size.

[-write-hit-60 <percent>] - 60% Cache Write Hit

This parameter indicates the predicted write hit rate when the cache size is 60% of the referenced cache size.

[-write-hit-80 <percent>] - 80% Cache Write Hit

This parameter indicates the predicted write hit rate when the cache size is 80% of the referenced cache size.

[-write-hit-100 <percent>] - 100% Cache Write Hit

This parameter indicates the predicted write hit rate when the cache size is 100% of the referenced cache size.
