You can use the aws cli to get a list of available metrics and dimensions:
```
aws cloudwatch list-metrics --namespace AWS/EC2 --region us-east-1
aws cloudwatch list-metrics --namespace AWS/EC2 --region us-east-1 --metric-name CPUCreditBalance
```
If the expected metrics are not returned, you can try getting them manually
for a short period of time:
```
aws cloudwatch get-metric-statistics --namespace AWS/EC2 --region us-east-1 --period 300 --start-time 2018-07-01T00:00:00Z --end-time 2018-07-01T00:15:00Z --statistics Average --metric-name CPUCreditBalance --dimensions Name=InstanceId,Value=i-deadbeef
```
### Example Output:
