Fluentd 更改输出封装

Question

I have a fluentd record

{"key": "value"}

but i wish to emit this record encapsulated inside an array (even if only one), like so:

[{"key": "value"}]

Is there any configuration i can use to obtain this result?

Answer 1

So, apparently this can be solved with fluentd in a recent version.

My problem is that i'm using an old version and this is not available.

See: https://docs.fluentd.org/output/http#json_array
