Viewing a cluster's details - Amazon ElastiCache for Redis
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Viewing a cluster's details

You can view detail information about one or more clusters using the ElastiCache console, Amazon CLI, or ElastiCache API.

You can view the details of a Redis (cluster mode disabled) cluster using the ElastiCache console, the Amazon CLI for ElastiCache, or the ElastiCache API.

The following procedure details how to view the details of a Redis (cluster mode disabled) cluster using the ElastiCache console.

To view a Redis (cluster mode disabled) cluster's details

  1. Sign in to the Amazon Web Services Management Console and open the Amazon ElastiCache console at https://console.amazonaws.cn/elasticache/.

  2. In the ElastiCache console dashboard, choose Redis to display a list of all your clusters that are running any version of Redis.

  3. To see details of a cluster, select the check box to the left of the cluster's name. Make sure that you select a cluster running the Redis engine, not Clustered Redis. Doing this displays details about the cluster, including the cluster's primary endpoint.

  4. To view node information:

    1. Choose the cluster's name.

    2. Choose the Shards and nodes tab. Doing this displays details about each node, including the node's endpoint which you need to use to read from the cluster.

    3. To view metrics on one or more nodes, select the box to the left of the node ID, then choose the time range for the metrics from the Time range list. If you choose multiple nodes, you can see overlay graphs.

You can view the details of a Redis (cluster mode enabled) cluster using the ElastiCache console, the Amazon CLI for ElastiCache, or the ElastiCache API.

The following procedure details how to view the details of a Redis (cluster mode enabled) cluster using the ElastiCache console.

To view a Redis (cluster mode enabled) cluster's details

  1. Sign in to the Amazon Web Services Management Console and open the Amazon ElastiCache console at https://console.amazonaws.cn/elasticache/.

  2. From the list in the upper-right corner, choose the Amazon Region you are interested in.

  3. In the ElastiCache console dashboard, choose Redis to display a list of all your clusters that are running any version of Redis.

  4. To see details of a Redis (cluster mode enabled) cluster, choose the box to the left of the cluster's name. Make sure you choose a cluster running the Clustered Redis engine, not just Redis.

    The screen expands below the cluster and display details about the cluster, including the cluster's configuration endpoint.

  5. To see a listing of the cluster's shards and the number of nodes in each shard, choose the cluster's name.

  6. To view specific information on a node:

    1. Choose the shard's ID.

    2. Choose the Nodes tab.

      Doing this displays information about each node, including each node's endpoint that you need to use to read data from the cluster.

    3. To view metrics on one or more nodes, choose the box by the node's ID, and then choose a time range for the metrics for Time range. Choosing multiple nodes generates overlay graphs.

The following code lists the details for my-cluster:

aws elasticache describe-cache-clusters --cache-cluster-id my-cluster

Replace my-cluster with the name of your cluster in a case where the cluster is created with 1 cache node and 0 shards using the create-cache-cluster command.

In a case where the cluster is created using the Amazon Web Services Management Console (cluster node enabled or disabled with 1 or more shards), use the following command to describe the cluster's details (replace my-cluster with the name of the replication group (name of your cluster):

aws elasticache describe-replication-groups --replication-group-id my-cluster

For more information, see the Amazon CLI for ElastiCache topic describe-cache-clusters.

You can view the details for a cluster using the ElastiCache API DescribeCacheClusters action. If the CacheClusterId parameter is included, details for the specified cluster are returned. If the CacheClusterId parameter is omitted, details for up to MaxRecords (default 100) clusters are returned. The value for MaxRecords cannot be less than 20 or greater than 100.

The following code lists the details for my-cluster.

https://elasticache.us-west-2.amazonaws.com/ ?Action=DescribeCacheClusters &CacheClusterId=my-cluster &Version=2015-02-02 &SignatureVersion=4 &SignatureMethod=HmacSHA256 &Timestamp=20150202T192317Z &X-Amz-Credential=<credential>

The following code list the details for up to 25 clusters.

https://elasticache.us-west-2.amazonaws.com/ ?Action=DescribeCacheClusters &MaxRecords=25 &Version=2015-02-02 &SignatureVersion=4 &SignatureMethod=HmacSHA256 &Timestamp=20150202T192317Z &X-Amz-Credential=<credential>
