Listing an ElastiCache parameter group's values

You can list the parameters and their values for a parameter group using the ElastiCache console, the AWS CLI, or the ElastiCache API.

Listing an ElastiCache parameter group's values (Console)

The following procedure shows how to list the parameters and their values for a parameter group using the ElastiCache console.

To list a parameter group's parameters and their values using the ElastiCache console

  1. Sign in to the AWS Management Console and open the ElastiCache console at https://console.aws.amazon.com/elasticache/.

  2. To see a list of all available parameter groups, in the left hand navigation pane choose Parameter Groups.

  3. Choose the parameter group for which you want to list the parameters and values by choosing the box to the left of the parameter group's name.

    The parameters and their values will be listed at the bottom of the screen. Due to the number of parameters, you may have to scroll up and down to find the parameter you're interested in.

Listing a parameter group's values (AWS CLI)

To list a parameter group's parameters and their values using the AWS CLI, use the command describe-cache-parameters.

The following sample code list all the Memcached parameters and their values for the parameter group myMem14.

For Linux, macOS, or Unix:

aws elasticache describe-cache-parameters \
    --cache-parameter-group-name myMem14

For Windows:

aws elasticache describe-cache-parameters ^
    --cache-parameter-group-name myMem14

The following sample code list all the parameters and their values for the parameter group myRedis28.

For Linux, macOS, or Unix:

aws elasticache describe-cache-parameters \
    --cache-parameter-group-name myRedis28

For Windows:

aws elasticache describe-cache-parameters ^
    --cache-parameter-group-name myRed28

For more information, see describe-cache-parameters.

Listing a parameter group's values (ElastiCache API)

To list a parameter group's parameters and their values using the ElastiCache API, use the DescribeCacheParameters action.

The following sample code list all the Memcached parameters for the parameter group myMem14.
