Installation

Please follow the installation guide on how to install and use this library.

Then, add custom instrumentation or use one of the framework integrations to automatically gain performance insights and error notifications. Currently, AppSignal has framework integrations for Phoenix and Plug applications.

Usage

AppSignal will automatically monitor requests, report any exceptions that are thrown and any performance issues that might have occurred.

You can also add extra information to requests by adding custom instrumentation. Read more in our instrumentation guide.

Configuration

A complete list of all configurable options for AppSignal for Elixir is available in our documentation.

Development

Setup

Before you can start developing on the AppSignal for Elixir project make sure you have Elixir installed.

Then make sure you have all the project's dependencies installed by running the following command:

$ mix deps.get

Testing

Testing is done with ExUnit and can be run with the mix test command. You can also supply a path to a specific file path you want to test and even a specific line on which the test you want to run is defined.

$ mix test
$ mix test test/appsignal/some_test.ex:123

This project has several different test suites defined with different mix environments. You can run them by specifying the specific type of test suite in the MIX_ENV environment variable.

# Default
$ MIX_ENV=test mix test

# Run the test suite with the NIF inoperational. This will generate errors
# because the NIF is not active, but should run without failures.
$ MIX_ENV=test_no_nif mix test

Benchmarking

This package uses benchee to benchmark code. To run the benchmarker:

$ MIX_ENV=bench mix run bench/<file>.exs

Branches and versions

The main branch corresponds to the current release of the library. The develop branch is used for development of features that will end up in the next minor release. If you fix a bug open a pull request on main, if it's a new feature on develop.
