Highlights

  • Enable API Catalog for AppSec with added http.route tag
  • Add preview support for correlating profiling with otel ruby gem
  • Disable crashtracking by default due to an unexpected interaction with the Process.wait family of calls

Allocation Profiling is now GA

As of both version 2.3.0 and 2.4.0 the allocation profiling feature is now generally available.

See our announcement blog post for more details.

You can enable this feature by using the DD_PROFILING_ALLOCATION_ENABLED=true environment variable, or via code:

Datadog.configure do |c|
  # ... existing configuration ...
  c.profiling.allocation_enabled = true
end

GVL profiling for Ruby 3.2+ is now in preview

Inspired on "Understanding the Ruby Global VM Lock by observing it"
the profiler is now able to show when threads are waiting for the Ruby GVL.

You'll be able to spot when threads are prevented from working by other "noisy neighbor" threads, including background threads. See #3929 for screenshots and more details. Note that currently this feature requires Ruby 3.2+.

You can enable this feature by using the DD_PROFILING_PREVIEW_GVL_ENABLED=true environment variable, or via code:

Datadog.configure do |c|
  # ... existing configuration ...
  c.settings.profiler.advanced.preview_gvl_enabled = true
end
