mon-get-stats

Description

Gets time-series data for the specified statistics.

Note

When you create a new metric using the mon-put-data command, it can take up to two minutes before you can retrieve statistics on the new metric using the mon-get-stats command. However, it can take up to fifteen minutes before the new metric appears in the list of metrics retrieved using the mon-list-metrics command.

Syntax

mon-get-stats MetricName --namespace value --statistics value[,value...] [--dimensions "key1=value1,key2=value2..." ] [--end-time value] [--period value] [--start-time value] [--unit value] [Common Options]

Options

Name Description

MetricName

The name of the metric. You can also set this value using --metric-name.

Type: Argument

Valid values: Any valid metric name between 1 and 255 characters.

Default: n/a

Required: Yes

--dimensions "key1=value1,key2=value2..."

The dimensions of the metric. You can specify dimensions two ways and the formats can be combined or used interchangeably:

  • One option per dimension: --dimensions "key1=value1" --dimensions "key2=value2"

  • All in one option: --dimensions "key1=value1,key2=value2"

Type: Map

Valid values: A string of the format name=value, where the key is the name of the dimension, and the value is the dimension's value. The dimension names, and values must be an ANSI string between 1 and 250 characters long. A maximum of 10 dimensions are allowed.

Default: n/a

Required: No

--end-time VALUE

The latest allowed timestamp for returned data points. The ending time is exclusive. Timestamps are specified using ISO8601 combined format. For example the date and time July 30th, 2013 at 12:30:00 PST would be represented as 2013-07-30T12:30:00-07:00, or in UTC: 2013-07-30T19:30:00Z. The highest resolution that can be returned by CloudWatch is 1 minute, as such all timestamps are rounded down to the nearest minute.

Type: Argument

Valid values: A valid timestamp represented in ISO8601 format with time zone offset, or UTC indicator.

Default: The current date/time.

Required: No

-n, --namespace VALUE

The namespace of the metric. For more information about namespaces, see AWS Namespaces.

Type: String

Valid values: A valid namespace between 1 and 250 characters in length.

Default: n/a

Required: Yes

--period VALUE

The granularity, in seconds, to retrieve statistics for. The period must be at least 60 seconds and must be a multiple of 60.

Type: Argument

Valid values: A number, in seconds that is a multiple of 60 seconds.

Default: 60 seconds.

Required: No

-s, --statistics VALUE1,VALUE2,VALUE3...

The statistics to be returned for the specified metric.

Type: Enumeration

Valid values: Average, Sum, Maximum, or Minimum

Default: n/a

Required: Yes

--start-time VALUE

The first allowed timestamp for returned data points. The starting time is inclusive. Timestamps are specified using ISO8601 combined format. For example the date and time July 30th, 2013 at 12:30:00 PST would be represented as 2013-07-30T12:30:00-07:00, or in UTC: 2013-07-30T19:30:00Z. The highest resolution that can be returned by CloudWatch is 1 minute, as such all timestamps are rounded down to the nearest minute.

Type: Argument

Valid values: A valid timestamp represented in ISO8601 format with time zone offset, or UTC indicator.

Default: One hour before the current time.

Required: No

--unit VALUE

The unit to retrieve the metrics for. Metrics may be reported in multiple units, this retrieve a specific unit for a given metric. Not requesting a unit will result in all units being returned. If the metric is only ever reported with one unit this will have no effect.

Type: Enumeration

This parameter must be used in conjunction with EC2_CERT, otherwise the value is ignored. The value of the environment variable EC2_PRIVATE_KEY will be used if it is set, and this option is not specified. This option is ignored if the environment variable AWS_CREDENTIAL_FILE is set, or --aws-credentials-file is used. All requests to CloudWatch must be signed, otherwise the request is rejected.
