SentryLoggerBackend

Provides a Logger backend for Sentry, to automatically submit Logger events above a configurable threshold to Sentry

Installation

1. Add sentry_logger_backend to your list of dependencies in mix.exs:

def deps do
  [{:sentry_logger_backend, "~> 0.1.0"}]
end

1. Add SentryLoggerBackend to the list of logger backends in your config, e.g.

config :logger, backends: [:console, SentryLoggerBackend]

1. Set the level threshold (defaults to :error - but see warning below):

config :logger, SentryLoggerBackend, level: :error

Fingerprints

Can supply a custom fingerprint to a Logger call with the fingerprint metadata, which should be a list(String.t) (see Sentry’s documentation for more info). For example:

Logger.warn "oh no - #{debugging data that's different each time}", fingerprint: ["oh-no"]

Please note if setting level to :warn, :info, or :debug

The current version of elixir-sentry logs problems encountered while posting to sentry at the :warn level.

That means that if you configure the level threshold to anything other than :error, and there’s a problem posting to sentry, then this can result in an infinite loop of error-posting attempts.

The suggested solution for now, if you want to use a threshold other than :error, is to use my fork of sentry-elixir, which adds :skip_sentry metadata to that logger call. Future plans are to include a custom http client in sentry-logger-backend, see https://github.com/SimonWoolf/sentry-logger-backend/issues/1 .
