The value NaN for parameter MetricData.member.11.Value is invalid

[Damian Duda]

I got this error and it contains little detail.

Aws::CloudWatch::Errors::InvalidParameterValue: The value NaN for parameter MetricData.member.11.Value is invalid.

It says that it errors out on member 11, which is probably the Utilization metric.

My guess is that the process["busy"] and process["concurrency"] were zero's - then we have this situation:

0 / 0.to_f
=> NaN

The question is why and when they would report zero's?

[Benjamin Curtis]

This is fixed by #14

[Dave Bradford]

Having this issue, any reason #14 isn't merged and release yet?

[Samuel Cochran]

Thanks, this should be fixed in version 2.4.0.
