NAME

elasticache-describe-cache-clusters - Describes Cache Clusters and
Nodes

SYNOPSIS

elasticache-describe-cache-clusters
[CacheClusterId] [--marker value ] [--max-records value ]
[--show-cache-node-info ] [General Options]

DESCRIPTION

Returns information about the cache clusters/nodes for this
account. If you
pass in a CacheClusterId, it will return information only about that
cluster. Otherwise it will return information for all of your caches,
up to
--max-records. Also, specifying --show-cache-node-info will return all
the
node information.

ARGUMENTS

CacheClusterId
User-supplied cache cluster identifier, this is the unique key that
identifies a cache cluster. The identifier must be 1 to 20
alphanumeric
characters or hyphens, is case insensitive, and is not case
preserving.
You can also set this value using "--cache-cluster-id".

SPECIFIC OPTIONS

-sn, --show-cache-node-info
Whether node level information is requested or not. The default
value is
'false'.

GENERAL OPTIONS

--aws-credential-file VALUE
Location of the file with your AWS credentials. This value can be
set by
using the environment variable 'AWS_CREDENTIAL_FILE'.

--connection-timeout VALUE
Specify a connection timeout VALUE (in seconds) for API calls. The
default value is '30'.

--debug
If an error occurs while --debug is used, it will display
information
useful for debugging the problem. The default value is 'false'.

--delimiter VALUE
What delimiter to use when displaying delimited (long) results.

--headers
If you are displaying tabular or delimited results, it includes the
column headers. If you are showing xml results, it returns the HTTP
headers from the service request, if applicable. This is off by
default.

-I, --access-key-id VALUE
Specify the AWS Access ID to use.

--marker VALUE
The marker provided in the previous request. If this parameter is
specified the response includes only records beyond the marker, up
to
MaxRecords.

--max-records VALUE
Maximum number of records to return per page. Allowed value range
for
this parameter is 20-100, default value is 100.

--region VALUE
Specify region VALUE as the web service region to use. This value
can be
set by using the environment variable 'EC2_REGION'.

-S, --secret-key VALUE
Specify the AWS Secret Key to use.

--show-empty-fields
Show empty fields and rows, using a "(nil)" value. The default is
to not
show empty fields or columns.

--show-request
Displays the URL used by the tools to call the AWS Service. The
default
value is 'false'.

--show-table, --show-long, --show-xml, --quiet
Specify how the results are displayed: tabular, delimited (long),
xml, or
no output (quiet). Tabular shows a subset of the data in fixed
column-width form, while long shows all of the returned values
delimited
by a character. The xml is the raw return from the service, while
quiet
suppresses all standard output. The default is tabular, or
'show-table'.

-U, --url VALUE
This option will override the URL for the service call with VALUE.
This
value can be set by using the environment variable
'AWS_ELASTICACHE_URL'.

OUTPUT

This command returns a table that contains the following:
* CacheClusterId - User-supplied cache identifier, this is the unique
key
that identifies a cache cluster for a customer.
* Created - The creation date of this cache cluster.
* Type - The compute and memory capacity of the cache cluster.
* Engine - Name of the cache engine to be used for this cache cluster.
* Status - The current status of the cluster.
* NumberOfNodes - The number of cache nodes within this cluster.
* PreferredAZ - The preferred availability zone of this cache cluster.
* Version - The cache engine's version number.
* Maintenance Window - The window during which patching and cluster
modifications will be performed. This column appears only in the
--show-long
view.
* PendingNumberCacheNodes - The number of nodes the cache cluster will
have
once any pending Add/Remove node actions are complete.
* PendingVersion - Version of the cache engine which will be deployed
during
the next maintenance window, or which is currently being deployed if
the
--apply-immdiately option was specified..
* Auto Minor Version Upgrade - Whether minor version upgrades will
automatically be applied to the cache cluster during its maintenance
window.
This column appears only in the --show-long view.
* Name - Security Group name.
* Status - Status of authorization.
* Group Name - Name of cache parameter group applied to.
* Apply Status - Status of applying the parameter group. It can be
either
in-sync or pending-reboot.
* CacheNodeId - Cache node identifier, this is the unique key that
identifies a cache cluster node.
* Created - The creation date of this cache cluster node.
* Status - The current status of the node.
* Address - Address used to connect to the cache cluster node.
* Port - Port used to connect to the cache cluster node.
* ParameterGroupStatus - The parameter group status for this node. If
this
node needs to be rebooted to apply parameter group changes, it will be

Otherwise it is in-sync.
* Topic Arn - Arn for SNS topic used to publish notifications related
to
cache clusters.
* Topic Status - Status of this SNS topic.
* Node ID - Node ID pending to be removed.
* Node ID - Node ID that needs to be rebooted to apply outstanding
