Blackfire Profiling

DDEV has built-in Blackfire integration.

Basic Blackfire Usage (Using Browser Plugin)

  1. Create a Blackfire account. (Free Blackfire accounts are no longer available; see Blackfire pricing.)
  2. Install the Chrome or Firefox browser plugin.
  3. From Blackfire’s control panel, get the Server ID, Server Token, Client ID, and Client Token from your Account → Credentials or environment.
  4. Configure DDEV with the credentials, ddev config global --web-environment-add="BLACKFIRE_SERVER_ID=<id>,BLACKFIRE_SERVER_TOKEN=<token>,BLACKFIRE_CLIENT_ID=<id>,BLACKFIRE_CLIENT_TOKEN=<token>". It’s easiest to do this globally, but you can do the same thing at the project level using ddev config --web-environment-add. (It may be easier to manually edit the relevant config file, .ddev/config.yaml or ~/.ddev/global_config.yaml.)
  5. ddev start.
  6. ddev blackfire on to enable, ddev blackfire off to disable, ddev blackfire status to see status.
  7. With Blackfire enabled, you can use the browser extension.

Profiling with the Blackfire CLI

The Blackfire CLI is built into the web container, so you don’t need to install it yourself.

  1. Add the BLACKFIRE_SERVER_ID, BLACKFIRE_SERVER_TOKEN, BLACKFIRE_CLIENT_ID, and BLACKFIRE_CLIENT_TOKEN environment variables to ~/.ddev/global_config.yaml via the web_environment key:

      web_environment:
  - OTHER_ENV=something
  - BLACKFIRE_SERVER_ID=dde5f66d-xxxxxx
  - BLACKFIRE_SERVER_TOKEN=09b0ec-xxxxx
  - BLACKFIRE_CLIENT_ID=f5e88b7e-xxxxx
  - BLACKFIRE_CLIENT_TOKEN=00cee15-xxxxx1

    You can also do this with ddev config global --web-environment-add="BLACKFIRE_SERVER_ID=<id>,BLACKFIRE_SERVER_TOKEN=<token>,BLACKFIRE_CLIENT_ID=<id>,BLACKFIRE_CLIENT_TOKEN=<token>", but any existing environment variables will be deleted.

  2. ddev start.

  3. ddev blackfire on.

  4. Click the “Blackfire” browser extension to profile.
