We just released appsignal gem version 2.1 which adds support for Alpine Linux and other musl-based systems.
With the rise of Docker we've noticed quite a few of our customers were using the smallest available Docker images, which were usually Alpine Linux based.
The AppSignal gem uses a C-extension written in Rust to speed up the gem and make a lot of code reusable for implementations in other languages, such as Elixir.
Recently the Rust team released a new version that allows us to compile our agent with support for musl and thus Alpine Linux. Many thanks from the AppSignal team!
We've deprecated two methods:
Appsignal.is_ignored_error?. These two methods will be removed in AppSignal
Ruby gem version 3. There is no replacement for these methods. The logic has
been moved to our agent.
