11. The Wall Clock Time, or Wall Time, for a function call is the measure of the real time it took for PHP to execute its code: the difference between the time at which PHP entered the function and the time at which PHP left the function
12. The CPU time is the amount of time the CPU was used for processing instructions.
13. The I/O time is the time the CPU waited for input/output (I/O) operations.
14. Network activity includes calls to databases like MySQL, PostreSQL, or MongoDB; HTTP calls to web services and APIs; calls to cache systems like Redis and Memcached; communications with services like queues, email daemons, remote filesystems; etc.
15. Disk activity occurs when a program reads files from the filesystem, including when PHP loads a script or class file.
16. Wall Time = CPU Time + I/O Time I/O Time = Network Time + Disk Time
17. The inclusive time allows you to find the critical path of an application.
18. The exclusive time allows to find the function calls to optimize first.

34. Assertions
35. .blackfire.yml tests: "Home Page": path: "/" assertions: - metrics.redis.connections.count == 1 - metrics.amqp.connections.count == 0 - main.memory < 40Mb
36. https://blackfire.io/docs/validator
39. Writing assertions on the main profile costs is as easy as adding a valid dimension name to the main. Prefix: • count • wall_time • cpu_time • memory • peak_memory • io • network_in • network_out
40. Test Scenarios
41. .blackfire.yml scenarios: Pricing page: - /pricing Integrations page: - /integrations Blackfire.yml Validator: - path: /docs/validator method: POST samples: 10
42. Only for HTTP requests, not CLI command
43. Blackfire and PHPUnit
44. composer require blackfire/php-sdk
