Solucionar problemas da extensão do Azure para SQL Server

2025-06-10

Aplica-se a:SQL Server

Este artigo descreve maneiras de identificar extensões não íntegras que não estão instaladas corretamente, em execução corretamente ou não conectadas ao Azure.

Identificar extensões prejudiciais

Usar o painel de integridade de extensão integrado no portal do Azure

Você pode usar o painel de integridade de extensão interno no portal do Azure para mostrar a integridade de todas as extensões do Azure implantadas para SQL Server.

Dica

Crie o seu próprio painel personalizado com este ficheiro do repositório sql-server-samples no GitHub: SQL Server habilitado para Arc Health.json.

Consultar extensões com problemas usando o Azure Resource Graph

Use o Azure Resource Graph para identificar o estado da extensão do Azure para SQL Server em seus servidores habilitados para Azure Arc.

Dica

Se ainda não estiver familiarizado, saiba mais sobre o Azure Resource Graph:

Esta consulta retorna instâncias do SQL Server em servidores com extensões instaladas, mas não saudáveis.

Para identificar possíveis problemas, reveja o valor na coluna RecommendedAction ou na coluna FailureReasons. A coluna RecommendedAction fornece possíveis primeiros passos para resolver o problema ou pistas sobre o que verificar primeiro. A coluna FailureReasons lista os motivos pelos quais o recurso foi considerado não saudável. Finalmente, verifique LastExtensionStatusMessage para ver a última mensagem relatada pelo agente.

Guia de solução de problemas

Ação Recomendada	Detalhes da ação
O certificado da máquina expirou. Vá para a máquina no portal do Azure para obter mais informações sobre como resolver esse problema.	A máquina habilitada para Arc deve ser reintegrada ao Arc porque o certificado usado para autenticar no Azure expirou. O status da máquina Arc é Expirado no portal do Azure. Desinstale o agente seguindo a documentação aqui e, em seguida, reintegre aqui. Não há necessidade de excluir os recursos do SQL Server habilitados para Arc no portal se você estiver reintegrando. A extensão SQL é instalada automaticamente novamente, contanto que a integração automática esteja habilitada (padrão).
A máquina está desconectada. Reconecte a máquina.	A máquina Arc está em uma `state = Disconnected`. Este estado pode ser por várias razões: O agente da máquina conectado ao Arc está parado, desativado ou constantemente a falhar. ou A conectividade está bloqueada entre o agente e o Azure. Verifique o estado dos serviços/daemons da máquina conectada ao Arc para garantir que eles estejam habilitados e em execução. Verifique a conectividade. Solucione problemas do agente usando o log detalhado.
Extensão relatada como insalubre. Exiba FailureReasons e LastExtensionStatusMessage para obter mais informações sobre a causa da falha. Último carregamento fora do intervalo aceitável (nos últimos três dias).	Verifique a coluna LastExtensionUploadTimestamp. Se for Sem carimbo de data/hora, nunca foi relatado dados de inventário ou uso para o Azure. Solucionar problemas de conectividade da extensão SQL para o Azure. Se o último carregamento estiver fora do intervalo aceitável (nos últimos três dias) e tudo o resto parecer OK, como LastExtensionUploadStatus, ExtensionProvisioningState e MachineStatus, é possível que o serviço/daemon da Extensão do Azure para SQL Server seja interrompido. Descubra por que ele está parado e inicie-o novamente. Verifique o LastExtensionStatusMessage para obter outras pistas sobre o problema.
O status de provisionamento de extensão é Falhou. Investigue e resolva o estado de provisionamento de extensão.	A instalação inicial da extensão SQL ou a atualização falhou. Verifique os logs do implantador e da extensão. Verifique o valor em LastExtensionStatusMessage.
O estado do carregamento não é reportado como OK	Verifique a coluna LastExtensionMessage no painel e veja o valor de uploadStatus e o valor de uploadMessage (se presente, dependendo da versão). O valor do uploadStatus é normalmente um código de erro HTTP. Consulte Solucionar problemas de códigos de erro. O uploadMessage pode ter informações mais específicas. Extensão Geral do Azure para a resolução de problemas de conectividade do SQL Server.
O status de provisionamento de extensão é Atualização ou O estado de provisionamento de extensão está criando ou O estado de provisionamento de extensão é Falhado ou O estado de provisionamento de extensão é Excluindo	Se uma determinada extensão permanecer em um desses estados por mais de 30 minutos, é provável que haja um problema com o provisionamento. Desinstale a extensão e reinstale-a usando a CLI ou o portal. Se o problema persistir, verifique o implantador e os logs de extensão. Se a exclusão falhar, tente desinstalar o agente e excluir o recurso da máquina Arc no portal, se necessário, e reimplante. Desinstale o agente seguindo a documentação aqui e, em seguida, reintegre aqui.

Identificar extensão não saudável (PowerShell)

Este exemplo é executado no PowerShell. O exemplo retorna o mesmo resultado da consulta anterior, mas por meio de um script do PowerShell.

# PowerShell script to execute an Azure Resource Graph query using Azure CLI
# where the extension status is unhealthy or the extension last upload time isn't in this month or the previous month.

# Requires the Az.ResourceGraph PowerShell module

# Login to Azure if needed
#az login

# Define the Azure Resource Graph query

Identificar extensões que faltam atualizações

Identifique extensões sem atualizações de status recentes. Essa consulta retorna uma lista de extensões do Azure para SQL Server ordenadas pelo número de dias desde a última atualização de status da extensão. Um valor de '-1' indica que a extensão falhou e há uma pilha de chamadas no status da extensão.

// Show the timestamp extracted
// If an extension has crashed (i.e. no heartbeat), fill timestamp with "1900/01/01, 00:00:00.000"
