Metricbeat stack modules may unmarshal large numbers into values Elasticsearch cannot understand

[ycombinator]

All stack modules in Metricbeat use the Go encoding/json package to unmarshal the JSON responses they get from various stack products' APIs.

Unless json.(*Decoder)UseNumber() is set for the json decoder it will produce float64 values for numbers if parses. And because the large numbers are float64 values when that get written into an event they end up encoded as a float in scientific notation which fails to be parsed by Elasticsearch at indexing time.
