Summary

cpuUtilization & nodeLag must 'double' type

Description

There was an error. In the code, the maximum value of Aurora MySQL double was entered, and there was an error that exceeded the allowable range when doing getFloat. When I looked up the official documentation, I found that the value was of type double.

Value '179,769,313,486,231,570,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000' is outside of valid range for type java.lang.Float

I think that the value is an error in Aurora, but if we don't fix it, I think the same error will occur next time.
