How to enable Blackfire

As the official Upsun observability service, Blackfire helps you improve the performance of your apps at each stage of their lifecycle. With Blackfire’s unique Application Performance Monitoring (APM) and Profiling features, you can achieve the following goals:

• Avoid performance bottlenecks by proactively identifying issues in your code
• Promptly solve identified issues by taking advantage of actionable recommendations
• Create performance budgets for critical parts of your app and get alerted of any problem before a change hits your production

Before you dig into the configuration process, check if your Upsun plan includes the Observability Suite as it includes an "out of the box" Blackfire integration which handles everything except builds.

Otherwise, depending on the tier and product you are using, find the appropriate steps in our Blackfire setup documentation.
