Hi

I have the plugin installed successfully, however, it's not sending data to CloudWatch.

This is a duplicate of https://github.com/awslabs/collectd-cloudwatch/issues/13

The problem here lies on the fact that the swap metric has a ´nan´ value. In order to get unblocked, please remove the swap metrics from the list of whitelisted metrics
