-- `frankenphp_[worker]_worker_request_time`: The time spent processing a requests by all workers.
-- `frankenphp_[worker]_worker_request_count`: The number of requests processed by all workers.
-- `frankenphp_total_threads`: The total number of php threads.
-- `frankenphp_busy_threads`: The number of php threads currently processing a request (running workers always consume a thread).
