Elixir package 1.8:

Tom Tom de Bruijn on

We’ve just released version 1.8 of the AppSignal for Elixir integration, which adds support for more precise values for custom metrics and adds the working_directory_path option to replace working_dir_path.

Doubles for custom metrics

Custom metrics always supported integers as values for the count metric. This allowed you to increment the counter with whole numbers, but not fractions. In Elixir package 1.8 you can increment the counter by 0.10, 0.20, 0.30, etc. Add that extra bit of precision to your counters!

Appsignal.increment_counter("metric_name", 3.14)

Read more about custom metrics in our docs.

New working_directory_path option

In this release we’ve reworked the option that configures where the AppSignal working directory is located. (Read about what the working directory is used for in our docs.)

There already was the working_dir_path option, but it’s behavior wasn’t completely self explanatory. For one, it appended /appsignal to the path.

# config/appsignal.exs
config :appsignal, :config,
  working_dir_path: "/tmp/my_app/"
  # would become
  working_dir_path: "/tmp/my_app/appsignal"

Instead working_directory_path will not append the path to the user specified path. It will create the specified path if it does not exist yet.

You can switch to the working_directory_path option without any additional configuration. Do note the /appsignal sub directory will no longer be created.

In this release we’ve also immediatly deprecated the working_dir_path option. Please use working_directory_path instead.

It’s also possible configure the working_directory_path option with an environment variable.

Other improvements

Please see the changelog for more details about these improvements, and bug fixes. And as always: get in touch if you encounter problems after upgrading. We’re happy to help!
