Changelog

Source

3.2.0

Published on 2024-03-06.

Added

  • a977204 patch - Add histogram support to the OpenTelemetry HTTP server. This allows OpenTelemetry-based instrumentations to report histogram data to AppSignal as distribution metrics.

Changed

  • 335324a minor - Breaking change: Normalize CPU metrics for cgroups v1 systems. When we can detect how many CPUs are configured in the container's limits, we will normalize the CPU percentages to a maximum of 100%. This is a breaking change. Triggers for CPU percentages that are configured for a CPU percentage higher than 100% will no longer trigger after this update. Please configure triggers to a percentage with a maximum of 100% CPU percentage.
  • 335324a patch - Support fractional CPUs for cgroups v2 metrics. Previously a CPU count of 0.5 would be interpreted as 1 CPU. Now it will be correctly seen as half a CPU and calculate CPU percentages accordingly.
  • f99d4c5 patch - Update bundled trusted root certificates.

Fixed

  • e5fa556 patch - Fix (sub)traces not being reported in their entirety when the OpenTelemetry exporter sends one trace in multiple export requests. This would be an issue for long running traces, that are exported in several requests.

This repository is a mono-managed repository. First install mono on your local machine by following the mono installation steps.

Then install the dependencies and prepare the project for development use using mono:

mono bootstrap

You can then run the following to start the compiler in watch mode.

npm run build:watch --parallel

You can also build the library without watching the directory:

mono build

Version management configuration is provided for asdf.

Testing

The tests for this library use Jest as the test runner. Once you've installed the dependencies, you can run the following command in the root of this repository to run the tests for all packages, or in the directory of a package to run only the tests pertaining to that package:
