[Al2Klimov]

... so Icinga DB can parse them as integers.

That's indeed one of the things that I find quite strange (especially these 200.0 status codes), so I'm happy to see this addressed. I remember writing workarounds for this in Python ages ago.

You should be able to parse a JSON int into a float/double value. However, for example in Go, unmarshalling into interface{} and then type asserting into float64 will break, so with some weird code, this might be incompatible.

Regarding the other side (so Icinga DB in this case): we still have to be careful to only try to parse values into ints for which we know for sure that this code will never return any decimals.
