MetricsCollectorElement

@Deprecated
public MetricsCollectorElement(ClientMetricsBinder binder,
 ObservabilitySettings settings)

Deprecated.

use MetricsCollectorElement(ClientMetricsBinder, ObservabilitySettings, boolean), which says whether the browser should gather an error's message and function name. This overload never gathers either, so an application wiring the element up by hand silently loses the detail insights-details asks for.

MetricsCollectorElement

public MetricsCollectorElement(ClientMetricsBinder binder,
 ObservabilitySettings settings,
 boolean collectErrorMessages)

Parameters:

collectErrorMessages - whether the in-browser collector should gather the message of an error it reports — the insights-details setting and something on the server willing to retain one

Method Details

onAttach

protected void onAttach(com.vaadin.flow.component.AttachEvent event)

Overrides:

onAttach in class com.vaadin.flow.component.Component

recordSamples

@ClientCallable
public void recordSamples(List<ClientSample> samples)
