# Get statistics for a specific instance
<a name="US_SingleMetricPerInstance"></a>

You can use the AWS Management Console or the AWS CLI to get statistics for a specific instance. The following examples show you how to use the AWS Management Console or the AWS CLI to determine the maximum CPU utilization of a specific EC2 instance.

**Requirements**
+ You must have the ID of the instance. You can get the instance ID using the AWS Management Console or the [describe-instances](https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instances.html) command.
+ By default, basic monitoring is enabled, but you can enable detailed monitoring. For more information, see [Manage detailed monitoring for your EC2 instances](manage-detailed-monitoring.md).

**To display the CPU utilization for a specific instance (console)**

1. Open the CloudWatch console at [https://console.aws.amazon.com/cloudwatch/](https://console.aws.amazon.com/cloudwatch/).

1. In the navigation pane, choose **Metrics**.

1. Choose the **EC2** metric namespace.

1. Choose the **Per-Instance Metrics** dimension.

1. In the search field, enter **CPUUtilization** and press Enter. Choose the row for the specific instance, which displays a graph for the **CPUUtilization** metric for the instance. To name the graph, choose the pencil icon. To change the time range, select one of the predefined values or choose **custom**.

1. To change the statistic or the period for the metric, choose the **Graphed metrics** tab. Choose the column heading or an individual value, and then choose a different value.

**To get the CPU utilization for a specific instance (AWS CLI)**  
Use the following [get-metric-statistics](https://docs.aws.amazon.com/cli/latest/reference/cloudwatch/get-metric-statistics.html) command to get the **CPUUtilization** metric for the specified instance, using the specified period and time interval:

```
aws cloudwatch get-metric-statistics --namespace AWS/EC2 --metric-name CPUUtilization  --period 3600 \
--statistics Maximum --dimensions Name=InstanceId,Value=i-1234567890abcdef0 \
--start-time 2022-10-18T23:18:00 --end-time 2022-10-19T23:18:00
```

The following is example output. Each value represents the maximum CPU utilization percentage for a single EC2 instance.
