Publishes metric data points to Amazon CloudWatch¶
Description¶
Publishes metric data points to Amazon CloudWatch. CloudWatch associates
the data points with the specified metric. If the specified metric does
not exist, CloudWatch creates the metric. When CloudWatch creates a
metric, it can take up to fifteen minutes for the metric to appear in
calls to list_metrics
.
You can publish either individual data points in the Value
field, or
arrays of values and the number of times each value occurred during the
period by using the Values
and Counts
fields in the MetricData
structure. Using the Values
and Counts
method enables you to publish
up to 150 values per metric with one put_metric_data
request, and
supports retrieving percentile statistics on this data.
Each put_metric_data
request is limited to 1 MB in size for HTTP POST
requests. You can send a payload compressed by gzip. Each request is
also limited to no more than 1000 different metrics.
Although the Value
parameter accepts numbers of type Double
,
CloudWatch rejects values that are either too small or too large. Values
must be in the range of -2^360 to 2^360. In addition, special values
(for example, NaN, +Infinity, -Infinity) are not supported.
You can use up to 30 dimensions per metric to further clarify what data the metric collects. Each dimension consists of a Name and Value pair. For more information about specifying dimensions, see Publishing Metrics in the Amazon CloudWatch User Guide.
You specify the time stamp to be associated with each data point. You can specify time stamps that are as much as two weeks before the current date, and as much as 2 hours after the current day and time.
Data points with time stamps from 24 hours ago or longer can take at
least 48 hours to become available for get_metric_data
or
get_metric_statistics
from the time they are submitted. Data points
with time stamps between 3 and 24 hours ago can take as much as 2 hours
to become available for for get_metric_data
or
get_metric_statistics
.
CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set instead, you can only retrieve percentile statistics for this data if one of the following conditions is true:
-
The
SampleCount
value of the statistic set is 1 andMin
,Max
, andSum
are all equal. -
The
Min
andMax
are equal, andSum
is equal toMin
multiplied bySampleCount
.
Usage¶
Arguments¶
Namespace
[required] The namespace for the metric data. You can use ASCII characters for the namespace, except for control characters which are not supported.
To avoid conflicts with Amazon Web Services service namespaces, you should not specify a namespace that begins with
AWS/
MetricData
[required] The data for the metric. The array can include no more than 1000 metrics per call.
Value¶
An empty list.
