v0.1.9 — May 22, 2026

Latest New
  • CPU utilisation gauge — process.runtime.cpu.usage (%) polled every 30 s. Uses /proc/self/stat on Linux and ps on macOS/BSD for a zero-dependency, subprocess-free implementation
  • Commit SHA auto-detection — service.commit_sha is now attached to every span, metric, and log without any configuration. Resolved from GITHUB_SHA, HEROKU_SLUG_COMMIT, RENDER_GIT_COMMIT, FLY_APP_VERSION, RAILWAY_GIT_COMMIT_SHA, or git rev-parse HEAD as fallback
  • !defined?(Rails::Console) pattern — the recommended way to silence SDK startup noise during rails console sessions without disabling telemetry in the server or workers
Improvements
  • Puma cluster mode / fork safety — Process._fork hook (Ruby 3.1+) restarts all background polling threads (memory, CPU, connection pool) inside each forked worker automatically
  • Connection pool poller now uses connection_handler.retrieve_connection_pool on Rails 7.2+ to avoid the soft-deprecation warning on ActiveRecord::Base.connection_pool
  • Memory poller reads /proc/self/status directly on Linux instead of spawning a ps subprocess — works in minimal Docker containers without procps
  • All background poller threads are marked abort_on_exception = false so a transient poll failure never brings down a worker
