Blackfire is a profiling tool and can be used to identify bottlenecks or areas of high resource consumption for your PHP application.
As with any profiling tool this package can have a slight impact on the performance of your website. We recommend you only enable Blackfire for your non-Production environments.
To install Blackfire for your UAT environment only, add the following configuration to your .platform.yml file:
environment:
uat:
packages:
blackfire:
server_id: "<server ID>"
server_token: "<server token>"
Your server ID and token are validated during a full deployment, and incorrect credentials may cause the deployment to fail.
Once the deployment is completed you can enable profiling within Blackfile and requests will start to appear.
