**To get the CPU utilization per EC2 instance**
The following example uses the ``get-metric-statistics`` command to get the CPU utilization for an EC2
instance with the ID i-abcdef.

**Specifying multiple dimensions**
The following example illustrates how to specify multiple dimensions. Each dimension is specified as a Name/Value pair, with a comma between the name and the value. Multiple dimensions are separated by a space. If a single metric includes multiple dimensions, you must specify a value for every defined dimension.
For more examples using the ``get-metric-statistics`` command, see `Get Statistics for a Metric`__ in the *Amazon CloudWatch Developer Guide*.
