Added

• Set data on spans with the custom_on_create_fun hook. This hook is called upon the creation of every span. This can be useful to add tags to internal traces and otherwise difficult to access traces.

  This won't be necessary for most scenarios. We recommend following our tagging guide instead.

  Elixir

  defmodule MyApp.Appsignal do
    def custom_on_create_fun(_span) do
      Appsignal.Span.set_sample_data(Appsignal.Tracer.root_span, "tags", %{"locale": "en"})
    end
  end

  Elixir

  # config/config.exs
  config :appsignal, custom_on_create_fun: &MyApp.Appsignal.custom_on_create_fun/1

Changed

• Make the debug log message for OpenTelemetry spans from libraries we don't automatically recognize more clear. Mention the span id and the instrumentation library.
• Fix an issue where queries containing a MySQL leading type indicator would only be partially sanitised.

See the changelog for AppSignal for Elixir package 2.8.3 for more information.
