Methods
Register the instrumentation with normalized options.

final void
register(array $options)
Register the instrumentation with normalized options.
at line 67
protected void
registerInstrumentation()
Register view observers and instruments.

AbstractInstrumentation at line 35
protected bool
tracesEnabled()
Determine whether trace output is enabled.

AbstractInstrumentation at line 43
protected bool
metricEnabled(string $name)
Determine whether a metric is enabled.

AbstractInstrumentation at line 53
protected bool
isDirectCancellation(Throwable|null $exception)
Determine whether the throwable is a direct coroutine cancellation.
Ending an operation by direct cancellation is control flow, not a failure.

AbstractInstrumentation at line 64
protected string
schemaUrl()
Return the semantic conventions schema URL for Hypervel instrumentation scopes.
Every tracer, meter and logger obtained for one scope must pass the same URL.
in
AbstractInstrumentation at line 79
protected array
indexObservers(array $names, array $observers)
Index callback observers by their matching instrument name.
The SDK supplies observers in the same order as the instruments passed to batchObserve(), so the unchanged name order is the mapping contract.

__construct(Factory $views, TracerProviderInterface $tracerProvider, MeterProviderInterface $meterProvider, ClockInterface $clock, LogContextScopeFactory $logContextScopes)
Create view instrumentation.
at line 99
protected void
start(View $view)
Start view-render telemetry.
at line 140
protected void
finish(View $view, Throwable|null $exception)
Complete view-render telemetry.
at line 187
protected ViewTelemetryState|null
takeState(View $view)
Remove and return the matching top view-render state.
