Not all CloudWatch metrics are available to select

[lyoungblood]

For some reason, when trying to create a metric that pulls data from NetworkELB, LoadBalancer, TargetGroup, not all of the metrics are visible or selectable from LambStatus. I was able to create this metric for one of my load balancers:

But, I want to select the metric for HealthyHosts for another load balancer, that is visible in CloudWatch metrics here, but is not visible or selectable in LambStatus:

OK, I’ll look into it.

Sorry for the late reply. I looked into the issue, but I can't find a bug. I actually created the network ELB resource and checked the related codes. The more detailed info may be helpful.

Some random thoughts are:

• The AWS region of the load balancer may be different.
• The IAM account which launched the CloudFormation stack doesn't have the permission to see that ELB.
• That ELB has some different settings than others.
• The lambda function [YourStackName]-GetExternalMetrics actually collects the metrics. See the /aws/lambda/[YourStackName]-GetExternalMetrics LogGroup of CloudWatch Logs.
