Statix

Statix is an Elixir client for StatsD-compatible servers. It is focused on speed without sacrificing simplicity, completeness, or correctness.

What makes Statix the fastest library around:

• direct sending to socket ^[1]
• caching of the UDP packet header
• connection pooling to distribute the metric sending
• diligent usage of IO lists

^[1] In contrast with process-based clients, Statix has lower memory consumption and higher throughput – Statix v1.0.0 does about 876640 counter increments per flush:

It is possible to measure that yourself.

for _ <- 1..10_000 do
  Task.start(fn ->
    for _ <- 1..10_000 do
      StatixSample.increment("sample", 1)
    end
  end)
end

Make sure you have StatsD server running to get more realistic results.

See the documentation for detailed usage information.

Why Forked Repo?

Statix Compatibility: Statix, does not yet support OTP-26. It is using Port.command instead of :gen_udp.send, as the former was considered more performant for OTP 25 and older versions. However, due to OTP updates occurring at the networking layer, this approach no longer works. Now, gen_udp.send has been optimized, rendering the previous workaround obsolete.

References

• Open PR: There is an open pull request in the Statix repository addressing this issue: Pull Request #72. This PR aims to update the codebase to support OTP-26 and utilize the optimized gen_udp.send function.

• Erlang Discussion: For further insights, you can refer to the Erlang discussion about the breaking change in Port.command for OTP-26: Issue #7130.

By utilizing the forked repository of Statix, we can maintain compatibility with OTP-26. As Statix evolves and potentially adds support for our current version, we aim to transition back to the main Statix repository. Alternatively, we'll explore alternatives should the need arise in the future.

Installation

Add Statix as a dependency to your mix.exs file:

defp deps() do
  [{:statix, ">= 0.0.0"}]
end

Then run mix deps.get in your shell to fetch the dependencies.
