AppSignal v1.0.0 Appsignal

Main library entrypoint.

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.

Summary

Functions

add_distribution_value(key, value)

Add a value to a distribution

config_change(changed, new, removed)

increment_counter(key, count \\ 1)

Increment a counter of some metric

phoenix?()

send_error(reason, message \\ "", stack \\ nil, metadata \\ %{}, conn \\ nil, fun \\ fn t -> t end)

Send an error to AppSignal

set_gauge(key, value)

Set a gauge for a measurement of some metric

start(type, args)

Application callback function

started?()

stop(state)

Application callback function

Functions

add_distribution_value(key, value)

add_distribution_value(String.t, float | integer) :: :ok

Add a value to a distribution

Use this to collect multiple data points that will be merged into a graph.

config_change(changed, new, removed)

increment_counter(key, count \\ 1)

increment_counter(String.t, integer) :: :ok

Increment a counter of some metric.

phoenix?()

send_error(reason, message \\ "", stack \\ nil, metadata \\ %{}, conn \\ nil, fun \\ fn t -> t end)

Send an error to AppSignal

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{}, "", nil, %{foo: "bar"})
Appsignal.send_error(%RuntimeError{}, "", nil, %{}, %Plug.Conn{peer: {{127, 0, 0, 1}, 12345}})
Appsignal.send_error(%RuntimeError{}, "", nil, %{}, nil, fn(transaction) ->
  Appsignal.Transaction.set_sample_data(transaction, "key", %{foo: "bar"})
end)

set_gauge(key, value)

set_gauge(String.t, float | integer) :: :ok

Set a gauge for a measurement of some metric.

start(type, args)

Application callback function

started?()

stop(state)
