v1.294.0

Recurso

Colheita antecipada

O agente agora poderá acionar colheitas antecipadas se certos critérios forem atendidos. Isso ajudará a garantir que mais carga seja mantida e vazamentos de memória sejam evitados. O agente iniciará uma coleta antecipada quando o tamanho do buffer de recurso atingir 16 KB; caso contrário, ele continuará coletando a cada 30 segundos, como antes. Este novo comportamento será aplicado ao seguinte evento:

• Solicitação Ajax
• BrowserInteraction
• BrowserPerformance
• Evento personalizado
• Log
• Ação de página
• Tempo de exibição de página
• Repetição da sessão
• Ação do Usuário

Um esforço separado será conduzido para permitir a coleta antecipada de timelice métrica, erros de javascript e rastreamento de sessão que usam outros mecanismos de armazenamento no agente.

Correções de bugs

reportar previousUrl vazio como indefinido

O atributo previousUrl no evento BrowserInteraction foi relatado como uma string vazia nos casos em que document.referrer está vazio. Isso fez com que o agrupamento de URL aplicasse o agrupamento em uma string vazia, levando à adição de grupos sem sentido a previousUrl. previousUrl agora é relatado como undefined para permitir que o agrupamento de URLs ignore URLs vazias.

Declaração de apoio

New Relic recomenda que você atualize o agente regularmente para garantir que esteja obtendo os benefícios mais recentes de recursos e desempenho. Versões mais antigas não terão mais suporte quando chegarem ao fim de sua vida útil. As datas de lançamento refletem a data de publicação original da versão do agente.

Novos lançamentos de agente do browser são disponibilizados aos clientes em pequenas etapas ao longo de um período de tempo.

v1.292.0

Adds new inspection events to the agent. These events include the drain event, window lifecycle events such as navigate, load, DOMContentLoaded, and the session event which emits on changes to the agent's session state.

Bug fixes

Fix finished API timeSinceLoad value

Fixes an issue where the finished api was creating a timeSinceLoad value for PageAction data as the unix timestamp instead of a relative time value in seconds from the page origin.

v1.291.1

Bug fixes

Prevent ST from holding onto Event refs in memory when aborted

Releases the Event entries the agent hold onto in Trace after it has aborted. This addresses a known case of memory leak caused by continuing to add those references to a Set that is never cleared.

Clean BrowserPerformance entryName for resources

The entryName attribute of resource type BrowserPerformance events will now have a cleaner URL, removing the hash fragment from reported URLs.

Add safeguards for addToTrace

Events created with addToTrace API, which have an invalid UNIX timestamp, emit a warning and return without creating the event.

v1.291.0

Features

Create the measure API

Adds the measure API to the newrelic global object. This API allows generating new BrowserPerformance data even if auto-detection of marks and measures is not enabled.

Bug fixes

Fix race between end of session and features aborting

Fix an issue where features would race with the session manager when a session ends. This required a check for session timings to match a given session and could create a state where a new session created from a pre-existing session would trigger a partial replay or no replay, and prevent the agent from sending trace data with a given replay.

Harvest first session trace payload immediately

For better consistency, implemented old behavior where the first ST payload is harvested immediately when the page loads. This helps ensure cases where replays are harvested but traces are not happen less frequently.
