1.12.0

Highlights

Remote configuration

• We fixed an issue with Passlist.

• We have added support for Custom In-App Waf Rules

• In previous versions, there was an issue with identifying the service name correctly. Everything, by default now should work as expected.

Mounted applications

• Appsec now supports mounted apps. That means you can instrument multiple services with appsec.
  Using the example of a Sinatra app mounted as part of a Rails application, you can now instrument both with AppSec. The configuration below should work now.

require 'datadog/appsec'

Datadog.configure do |c|
  c.appsec.enabled = true
  c.appsec.instrument :rails
  c.appsec.instrument :sinatra
end

Highlights

Remote Configuration

The Remote Configuration feature is now in General Availability.

What to expect from Remote Configuration?

ASM can now receive live updates via Remote Configuration, such as:

• protection rules, including request blocking
• IP and path passlists
• IP and user denylists

Remote Configuration will be progressively expanded to support other Datadog products such as APM.

How to configure Remote Configuration?

• Make sure ASM is enabled (see our documentation)
• Upgrade the Datadog agent to 7.42.0 or above (7.43.0 or above recommended)
• Configure the agent to allow Remote Configuration via e.g the environment variableDD_REMOTE_CONFIGURATION_ENABLED=true

To opt out of Remote Configuration, it can be done via either the environment variable DD_REMOTE_CONFIGURATION_ENABLED=false or Datadog.configure { |c| c.remote.enabled = false }.

Read more about Remote Configuration in our documentation

Ruby CPU Profiling 2.0

The new CPU Profiling 2.0 feature is now in General Availability.

What to expect from Ruby CPU Profiling 2.0?

• Finer-grained profiling data due to our sampling engine rewritten in C+Rust. The profiler will be able to run more often and get more information while keeping the same 2% overhead target you're used to, and with a lower impact on latency. Especially when looking at the "Code Hotspots" panel for a distributed trace, expect more and finer grained profiles.
• Thread id information now includes the operating system thread id for Ruby 3.1+, so you'll be able to correlate your thread information when looking at other system monitoring tools
• Thread names are now collected and you're able to filter your profiles by these names
• The profiler now exposes a Datadog::Profiling.allocation_count API that can be used to measure how many objects were allocated in parts of your application
• Experimental support for capturing CPU and Wall-time spent doing Garbage Collection. This is disabled by default as we're still improving the performance of this feature and fixing a few incompatibilities with Ruby Ractors. You can enable it by adding DD_PROFILING_FORCE_ENABLE_GC=true or c.profiling.advanced.force_enable_gc_profiling = true to the instructions seen above.

...with more and faster improvements to come soon!

If you're using the profiler, the new feature will be automatically enabled, except in the following cases:

• When running on Ruby 2.5 and below
• When the mysql2 or rugged gems are installed

Known issues:

• Rare incompatibilities with native extensions/libraries.

  Ruby CPU Profiling 2.0 gathers profiling data by sending SIGPROF unix signals to Ruby applications. This is a common approach used by many other profilers, and it may cause system calls performed by native extensions/libraries to be interrupted with an EINTR error code (reference).

  Most native extensions/libraries are unaffected by this issue, but we know that the mysql2 and rugged gems can trigger these issues (details). When either of these gems is detected, the new feature is not enabled.

  We expect these occurrences to be rare, and will be working to both improve the ecosystem as well as to deploy countermeasures in the profiler itself to avoid triggering these issues.

• Ruby 2.5 and below are missing an API that allows the profiler to detect the currently-active Ruby thread. We plan to ship a workaround for this issue soon.

• The disabled-by-default experimental support for capturing CPU and Wall-time spent doing Garbage Collection is incompatible with Ractors due to Ruby upstream bugs (https://bugs.ruby-lang.org/issues/18464 and https://bugs.ruby-lang.org/issues/19112). We plan to work with the Ruby developers to incorporate fixes for these issues.

• The disabled-by-default experimental support for capturing CPU and Wall-time spent doing Garbage Collection can cause a lot of overhead in Ruby applications with high object allocation rates.

Telemetry

The Telemetry feature is now in General Availability and enabled by default. It will allow Datadog to provide more efficient support.

Added

• Add remote configuration, enabled by default (#2674, #2678, #2686, #2687, #2688, #2689, #2696, #2705, #2731, #2732, #2733, #2739, #2756, #2769, #2771, #2773, #2789, #2805, #2794)

Give it a try, and we'd love to hear your feedback. Below, you'll find a list of known issues that we're still looking into.

Known issues:

• Rare incompatibilities with native extensions/libraries.

  Ruby CPU Profiling 2.0 gathers profiling data by sending SIGPROF unix signals to Ruby applications. This is a common approach used by many other profilers, and it may cause system calls performed by native extensions/libraries to be interrupted with an EINTR error code (reference).

  Most native extensions/libraries are unaffected by this issue, but we know of at least one case: when using the mysql2 gem together with versions of libmysqlclient older than 8.0.0 this can lead to failed database requests (reference). The affected libmysqlclient version is known to be present on Ubuntu 18.04, but not 20.04 and later releases.

  We expect these occurrences to be rare, and will be working to both improve the ecosystem as well as to deploy countermeasures in the profiler itself to avoid triggering these issues.

• Ruby 2.5 and below are missing an API that allows the profiler to detect the currently-active Ruby thread. We have deployed a workaround, but suspect that it may lead to crashes in extremely rare situations. We are still researching a solution for this issue and do not plan on rolling out CPU Profiling 2.0 automatically to Ruby 2.5 and below applications until it is fixed.

• redis 5 instrumentation upgrade notes

redis 5 instrumentation upgrade notes

dd-trace-rb officially supports redis 5 instrumentation. When upgrading redis gem to 5.x and with configuration per instance, change your code by passing {custom: datadog: { … }} tags during redis instantiation.

Before redis 5

customer_cache = Redis.new
invoice_cache = Redis.new

Datadog.configure_onto(customer_cache, service_name: 'customer-cache')
Datadog.configure_onto(invoice_cache, service_name: 'invoice-cache')

customer_cache.get(...)
invoice_cache.get(...)

After upgrading to redis 5.x

customer_cache = Redis.new(custom: { datadog: { service_name: 'custom-cache' } })
invoice_cache = Redis.new(custom: { datadog: { service_name: 'invoice-cache' } })

customer_cache.get(...)
invoice_cache.get(...)
