Measuring Latency and HTTP status with elixir

[idi527]

I’d rather use monotonic time if the code runs on a vm to avoid skews. And keep the measurements (request, parsing, etc) in the process dictionary (if needed).

How can I get the response time of a HTTP request in elixir?

I don’t know if that would work for you (I’ve seen it being used in knutin/elli), but if all of your work is done in a single process, you can put timings into the process dictionary: defp t(key) do :erlang.put({:time, key}, :os.timestamp()) end and call it in different places inside the same process t(:start_request) # request something t(:done_requesting) t(:start_parsing_body) # parse body t(:done_parsing_body) and then collect the timings at some point later (you would need to be in th…

But replace :os.timestamp() with :erlang.monotonic_time().
