to http.rb: a fast, easy-to-use Ruby HTTP client with a chainable API

I use http and access to fluentd server.

The procession is here.

def input_fluentd(body)

HTTP.timeout(write: 1, connect: 1, read: 1).post("#{ENV['FLUENTD_ENDPOINT_HTTP']}/user_action", json: body)

end

However, I get errors like below sometimes.

There are not a lot of accesses and the max of query per second is about 20.

What should I do?

```
