AppSignal v1.10.9 Appsignal View Source

AppSignal for Elixir. Follow the installation guide to install AppSignal into your Elixir app.

This module contains the main AppSignal OTP application, as well as a few helper functions for sending metrics to AppSignal.

These metrics do not rely on an active transaction being present. For transaction related-functions, see the Appsignal.Transaction module.

When there is no current transaction, this call starts one.

Examples

Appsignal.send_error(%RuntimeError{})
Appsignal.send_error(%RuntimeError{}, "Oops!")
Appsignal.send_error(%RuntimeError{}, "", System.stacktrace())
Appsignal.send_error(%RuntimeError{}, "", [], %{foo: "bar"})
Appsignal.send_error(%RuntimeError{}, "", [], %{}, %Plug.Conn{})
Appsignal.send_error(%RuntimeError{}, "", [], %{}, nil, fn(transaction) ->
  Appsignal.Transaction.set_sample_data(transaction, "key", %{foo: "bar"})
end)
