We have released AppSignal for Elixir package version 1.4 today. In this release we add support for FreeBSD systems, fix a crash when using multiple processes and fix the DNS timeouts issue for good.
To upgrade to the new version, simply run
mix deps.update appsignal, and you're good to go!
Fix for instrumenting multiple processes
Although we don't officially support it, a bug came up when adding instrumentation to a big number of asynchronous processes for one user. We now avoid a crash for this scenario, but don't support the use-case yet. This is something we want to take a look at for a future release of our Elixir package.
In the meantime, we wrote documentation on how to instrument asynchronous events in the same transaction. If this doesn't cover your scenario, please let us know.
The AppSignal agent now supports 64-bit FreeBSD, a platform we didn't support with the most recent versions of the AppSignal gem.
If you run your application on a FreeBSD system, please upgrade to the latest version of the AppSignal Elixir integration and let us know if you experience any problems with this new build.
The new FreeBSD build for the AppSignal agent does not support host metrics at this time. We hope to support this in a future release of the AppSignal Elixir integration.
Separate Alpine Linux build
In AppSignal for Elixir package 0.11.0 we switched to a musl compatible agent build to support Alpine Linux. An unforeseen consequence was that our agent became incompatible with certain DNS settings on other platforms.
We tried a couple of different solutions over the past few months, but the best way to solve this problem was to ship a separate Alpine Linux build. With this version, we can finally announce that the DNS timeouts issue is resolved. Please upgrade to AppSignal for Elixir package version 1.4.0 or higher if you ever had this problem.
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!
