Add InstanceType tag in CloudWatch Exporter result for aws ec2 instance metric

[chuanjia xing]

Hi,

    I am using Prometheus CloudWatch Exporter to query EC2 instance CPUUtilization metrics. My config file for the Exporter is as follows:

---

region: us-west-2

role_arn: [My-Role-Arn]

metrics:

- aws_namespace: AWS/EC2

aws_metric_name: CPUUtilization

aws_dimensions: [InstanceId]

aws_tag_select:

resource_type_selection: "ec2:instance"

resource_id_dimension: "InstanceId"

aws_extended_statistics: [p50, p90]

aws_statistics: [Average]

    One of the output from Export is like follows:

aws_ec2_cpuutilization_average{job="aws_ec2",instance="",instance_id="i-12345abcde",} 1.33333333341094 1617906240000

     Now I want to add the "InstanceType" information in this output for each instance. I checked this information is not under "Tag" for the instance so I can't add it from there. 

      Is there any way to add this information? Thanks.
