[Blackfire.io](https://blackfire.io/) is a service that allows code profiling to be stored and analyzed via an online profile on the Blackfire.io website.
|
|
|
|
It doesn't require any additional Drupal modules to use, but once you've made sure `blackfire` is in the list of `installed_extras` in `config.yml` (and Drupal VM has been provisioned), you need to log into Drupal VM and [run the setup steps outlined on the Blackfire Ansible role's README](https://github.com/geerlingguy/ansible-role-blackfire#requirements).
|
|
|
|
**Note**: You should only enable one code profiler at a time—e.g. when using [Blackfire](blackfire.md), disable [XHProf](xhprof.md), [Tideways](tideways.md) and [XDebug](xdebug.md).
|
|
|
|
Once you've configured your environment for your own Blackfire account, you can profile a request with Blackfire by running something like the following example (within Drupal VM, after logging in with `vagrant ssh`):
|
|
|
|
```
|
|
$ blackfire curl http://drupalvm.test/
