WebAppInfo Collector

Collects web application performance metrics — request processing time, preload time, emit time, memory usage, and adapter name.

What It Captures

Field	Description
applicationProcessingTime	Total application processing time
requestProcessingTime	Request handling time
applicationEmit	Response emit time
preloadTime	Bootstrap/preload time
memoryPeakUsage	Peak memory usage in bytes
memoryUsage	Current memory usage in bytes
adapter	Framework adapter name

INFO

WebAppInfoCollectorAppDevPanel\Kernel\Collector\Web\WebAppInfoCollectorCollects Web App Info data during application lifecycle.final Kernel · class · implements SummaryCollectorInterface implements SummaryCollectorInterfaceAppDevPanel\Kernel\Collector\SummaryCollectorInterfaceSummary data collector responsibility is to collect summary data for a collector. Summary is used to display a list of previous requests and select one to display full info. Its data set is specific to the list and is reduced compared to full data collected in {@see CollectorInterface}.Kernel · interface · extends CollectorInterface and depends on TimelineCollectorAppDevPanel\Kernel\Collector\TimelineCollectorCollects Timeline data during application lifecycle.final Kernel · class · implements SummaryCollectorInterface. Located in the Web sub-namespace.

How It Works

Framework adapters call the mark*() methods at key points in the request lifecycle — application boot, request start, request end, and response emit. Memory metrics are captured via memory_get_peak_usage() and memory_get_usage().

Debug Panel

The WebAppInfo data is displayed in the top bar of every debug entry as processing time and memory usage, rather than having a dedicated panel.
