Listing ElastiCache parameter groups by name

You can list the parameter groups using the ElastiCache console, the AWS CLI, or the ElastiCache API.

Listing parameter groups by name (Console)

The following procedure shows how to view a list of the parameter groups using the ElastiCache console.

To list parameter groups using the ElastiCache console

Sign in to the AWS Management Console and open the ElastiCache console at https://console.aws.amazon.com/elasticache/.
To see a list of all available parameter groups, in the left hand navigation pane choose Parameter Groups.

Listing ElastiCache parameter groups by name (AWS CLI)

To generate a list of parameter groups using the AWS CLI, use the command describe-cache-parameter-groups. If you provide a parameter group's name, only that parameter group will be listed. If you do not provide a parameter group's name, up to --max-records parameter groups will be listed. In either case, the parameter group's name, family, and description are listed.

The following sample code lists the parameter group myMem14.

For Linux, macOS, or Unix:


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

For Windows:


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

The output of this command will look something like this, listing the name, family, and description for the parameter group.


{
    "CacheParameterGroups": [
	    {
	        "CacheParameterGroupName": "myMem14", 
	        "CacheParameterGroupFamily": "memcached1.4", 
	        "Description": "My first parameter group"
	    }
    ]
}

The following sample code lists the parameter group myRed28.

For Linux, macOS, or Unix:


aws elasticache describe-cache-parameter-groups \
    --cache-parameter-group-name myRed28

For Windows:


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

The output of this command will look something like this, listing the name, family, and description for the parameter group.


{
    "CacheParameterGroups": [
	    {
	        "CacheParameterGroupName": "myRed28", 
	        "CacheParameterGroupFamily": "redis2.8", 
	        "Description": "My first parameter group"
	    }
    ]
}

The following sample code lists the parameter group myRed56 for parameter groups running on Redis OSS engine version 5.0.6 onwards. If the parameter group is part of a Replication across AWS Regions using global datastores, the IsGlobal property value returned in the output will be Yes.

For Linux, macOS, or Unix:


aws elasticache describe-cache-parameter-groups \
    --cache-parameter-group-name myRed56

For Windows:


aws elasticache describe-cache-parameter-groups ^
    --cache-parameter-group-name myRed56

The output of this command will look something like this, listing the name, family, isGlobal and description for the parameter group.


{
    "CacheParameterGroups": [
	    {
	        "CacheParameterGroupName": "myRed56", 
	        "CacheParameterGroupFamily": "redis5.0", 	        
	        "Description": "My first parameter group",
	        "IsGlobal": "yes"	        
	    }
    ]
}

The following sample code lists up to 10 parameter groups.


aws elasticache describe-cache-parameter-groups --max-records 10

The JSON output of this command will look something like this, listing the name, family, description and, in the case of redis5.6 whether the parameter group is part of a global datastore (isGlobal), for each parameter group.

Listing ElastiCache parameter groups by name (ElastiCache API)

To generate a list of parameter groups using the ElastiCache API, use the DescribeCacheParameterGroups action. If you provide a parameter group's name, only that parameter group will be listed. If you do not provide a parameter group's name, up to MaxRecords parameter groups will be listed. In either case, the parameter group's name, family, and description are listed.

The following sample code lists the parameter group myMem14.
