aws_dimensions should be all dimensions on the metric. I don't use CWAgent, but apparently there are more on these metrics than you listed. What happens when you add all the dimensions?

Once you get it working, could you please add an example?

[pikodd]

The question is irrelevant anymore

@pikodd how did you fixed this problem? I am having the similar issue with my CWAgent metrics.

I haven't fixed it :)) Just used Node exporter on every ec2 instance.

@pikodd thanks, going through mutiple issues. I think the exporter is currently unable to bring metrics from custom namespace.
