Hi,

I don’t believe JSON supports the “NaN” “inf” and/or “-inf” values. Depending on how you are getting these values, that would need to be replaced with “null” or something similar.

The elasticsearch output has a “float_handling” option that defaults to none. When set to “replace” it will use some pre-defined value to replace those types of values. When set to “drop” it will remove them.

You could possibly do this with a regex or starlark processors.
