Timeline view for Profiler beta

As of ddtrace 1.15.0, the Profiler now supports gathering data for the new Timeline view.

The Timeline view allows you to look at time-based patterns and work distribution over the period of a single profile: you can look at what individual threads were doing, and when 🎉

You can use the timeline view both when looking at individual profiles, as well as when scoped to a given trace.

You can enable it:

• Using an environment variable by setting DD_PROFILING_EXPERIMENTAL_TIMELINE_ENABLED=true
• Or via code by adding to your Datadog.configure block:

Datadog.configure do |c|
  # … existing configuration …
  c.profiling.advanced.experimental_timeline_enabled = true
end

Give it a try, let us know what you think!

(Note: We do not recommend enabling this feature prior to 1.15.0!)

google-protobuf dependency is no longer needed by the Profiler

As of ddtrace version 1.15.0, the google-protobuf gem is no longer needed to enable the Profiler.

If you've added this gem to your Gemfile/gems.rb file as part of enabling the Profiler, you can
remove it now. (If you're curious, we've internally replaced this dependency with the libdatadog gem.)

Configure blocking responses for AppSec via configuration or Remote Configuration

As of dd-trace-rb 1.15.0, AppSec supports configuring the blocking response.

You can configure the blocking response via:

• Using the ENV variables: DD_APPSEC_HTTP_BLOCKED_TEMPLATE_HTML=#{file_name}, and DD_APPSEC_HTTP_BLOCKED_TEMPLATE_JSON=#{file_name}
• Via code by adding to your Datadog.configure block:

Datadog.configure do |c|
  # … existing configuration …
  c.appsec.block.templates.html = "#{file_name}"
  c.appsec.block.templates.json = "#{file_name}"
end

• Using the Remote configuration UI. This option allows you to configure the status code and the blocking behaviour. You can redirect malicious attackers to custom pages.
  You can find more information on the official documentation

Configure agentless mode for CI visibility

If you are using CI visibility with a cloud CI provider without access to the underlying worker nodes, such as GitHub Actions or CircleCI, configure the library to use the Agentless mode.

For this, set the following environment variables:

• DD_CIVISIBILITY_AGENTLESS_ENABLED=true
• DD_API_KEY=<your_api_key>

Additionally, configure which Datadog site you want to send your data to:

• DD_SITE (default: datadoghq.com)

You can also enable agentless mode with Datadog.configure block:

Datadog.configure do |c|
  # … existing configuration …
  c.ci.agentless_mode_enabled = true
  # don't forget to set DD_API_KEY env variable!
end
