put-metric-data

Description

Publishes metric data points to Amazon CloudWatch. Amazon CloudWatch associates the data points with the specified metric. If the specified metric does not exist, Amazon CloudWatch creates the metric. When Amazon CloudWatch creates a metric, it can take up to fifteen minutes for the metric to appear in calls to list-metrics .

Each put-metric-data request is limited to 40 KB in size for HTTP POST requests.

Although the Value parameter accepts numbers of type Double , Amazon CloudWatch rejects values that are either too small or too large. Values must be in the range of 8.515920e-109 to 1.174271e+108 (Base 10) or 2e-360 to 2e360 (Base 2). In addition, special values (e.g., NaN, +Infinity, -Infinity) are not supported.

You can use up to 10 dimensions per metric to further clarify what data the metric collects. For more information on specifying dimensions, see Publishing Metrics in the Amazon CloudWatch User Guide .

Data points with time stamps from 24 hours ago or longer can take at least 48 hours to become available for get-metric-statistics from the time they are submitted.

CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set instead, you cannot retrieve percentile statistics for this data unless one of the following conditions is true:

  • The SampleCount of the statistic set is 1
  • The Min and the Max of the statistic set are equal

Synopsis

  put-metric-data
--namespace <value>
[--metric-data <value>]
[--metric-name <value>]
[--timestamp <value>]
[--unit <value>]
[--value <value>]
[--dimensions <value>]
[--statistic-values <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--namespace (string)

The namespace for the metric data.

You cannot specify a namespace that begins with "AWS/". Namespaces that begin with "AWS/" are reserved for use by Amazon Web Services products.

--metric-data (list)

The data for the metric.

Shorthand Syntax:

MetricName=string,Dimensions=[{Name=string,Value=string},{Name=string,Value=string}],Timestamp=timestamp,Value=double,StatisticValues={SampleCount=double,Sum=double,Minimum=double,Maximum=double},Unit=string ...

JSON Syntax:

[
  {
    "MetricName": "string",
    "Dimensions": [
      {
        "Name": "string",
        "Value": "string"
      }
      ...
    ],
    "Timestamp": timestamp,
    "Value": double,
    "StatisticValues": {
      "SampleCount": double,
      "Sum": double,
      "Minimum": double,
      "Maximum": double
    },
    "Unit": "Seconds"|"Microseconds"|"Milliseconds"|"Bytes"|"Kilobytes"|"Megabytes"|"Gigabytes"|"Terabytes"|"Bits"|"Kilobits"|"Megabits"|"Gigabits"|"Terabits"|"Percent"|"Count"|"Bytes/Second"|"Kilobytes/Second"|"Megabytes/Second"|"Gigabytes/Second"|"Terabytes/Second"|"Bits/Second"|"Kilobits/Second"|"Megabits/Second"|"Gigabits/Second"|"Terabits/Second"|"Count/Second"|"None"
  }
  ...
]

--metric-name (string) The name of the metric.

--timestamp (string) The time stamp used for the metric. If not specified, the default value is set to the time the metric data was received.

--unit (string) The unit of metric.

--value (string) The value for the metric. Although the --value parameter accepts numbers of type Double, Amazon CloudWatch truncates values with very large exponents. Values with base-10 exponents greater than 126 (1 x 10^126) are truncated. Likewise, values with base-10 exponents less than -130 (1 x 10^-130) are also truncated.

--dimensions (string) The --dimensions argument further expands on the identity of a metric using a Name=Value pair, separated by commas, for example: --dimensions InstanceID=1-23456789 InstanceType=m1.small . Note that the --dimensions argument has a different format when used in get-metric-data , where for the same example you would use the format --dimensions Name=InstanceID,Value=i-aaba32d4 Name=InstanceType,value=m1.small .

--statistic-values (string) A set of statistical values describing the metric.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To publish a custom metric to Amazon CloudWatch

The following example uses the put-metric-data command to publish a custom metric to Amazon CloudWatch:

aws cloudwatch put-metric-data --namespace "Usage Metrics" --metric-data file://metric.json

The values for the metric itself are stored in the JSON file, metric.json.

Here are the contents of that file:

[
  {
    "MetricName": "New Posts",
    "Timestamp": "Wednesday, June 12, 2013 8:28:20 PM",
    "Value": 0.50,
    "Unit": "Count"
  }
]

For more information, see Publishing Custom Metrics in the Amazon CloudWatch Developer Guide.

To specify multiple dimensions

The following example illustrates how to specify multiple dimensions. Each dimension is specified as a Name=Value pair. Multiple dimensions are separated by a comma.:

aws cloudwatch put-metric-data --metric-name Buffers --namespace MyNameSpace --unit Bytes --value 231434333 --dimensions InstanceID=1-23456789,InstanceType=m1.small

Output

None
