# Monitor Infrastructure Performance using the AWS CLI
<a name="nmip-performance-cli"></a>

[GetAwsNetworkPerformanceData](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_GetAwsNetworkPerformanceData.html) returns network performance metrics. For more information, see [GetAwsNetworkPerformanceData](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_GetAwsNetworkPerformanceData.html). 

In the following example, network performance is queried between two Regions, `us-east-1` and `us-west-2` on `2022-10-26` between a start-time of `12:00:00` and an end time of `12:30:00`. The request also uses the following parameters:
+ `Metric` indicates what type of metric is being requested. In this example, `aggregate-latency`, indicates that the performance metrics are aggregated and returned for latency.
+  `Statistic` is the median value of the metric. In this example, `p50` is the statistic of all the data points gathered within those five minutes.
**Note**  
`p50` is the only supported statistic.
+ `Period` indicates the interval at which performance the `metric` is returned. In this example, `aggregated-latency` metrics are returned for every `five-minutes`.

```
aws ec2 --region ap-southeast-3 get-aws-network-performance-data --start-time
   2022-10-26T12:00:00.000Z --end-time 2022-10-26T12:30:00.000Z --data-queries
   Id=id1,Source=us-east-1,Destination=us-west-2,Metric=aggregate-latency,Statistic=p50,Period=five-minutes
```

The results return the following:

```
