Custom Meter in CloudWatch

Question

How many requests per minute can I send for each custom metric in CloudWatch?

ps I know that the standard metric is 1 minute.

Answer 1

Here's a quote from the Publishing Individual Data Points section of the Amazon CloudWatch Developer Guide :

Even though you can publish data points with timestamps of up to one thousandth of a second, Amazon CloudWatch aggregates data with a minimum of detail of one minute.
