Monitorize as reservas do BigQuery
Como administrador do BigQuery, pode monitorizar as reservas no seu projeto vendo a utilização de slots do projeto e da reserva, bem como a fatura baseada na capacidade.
Veja a utilização de projetos e de slots de reserva
Pode ver a utilização do projeto e do intervalo de reserva das seguintes formas:
INFORMATION_SCHEMAvisualizações. Para obter informações sobre a utilização de projetos e reservas, consulte as vistasINFORMATION_SCHEMA.JOBS*.O campo
reservation_idnas visualizaçõesINFORMATION_SCHEMA.JOBS*contém o nome da reserva.Google Cloud console. A Google Cloud consola inclui gráficos que apresentam a utilização de espaços. Para mais informações, consulte o artigo Use gráficos de recursos administrativos.
Registos de auditoria. Use registos de auditoria para ver métricas sobre a utilização de slots.
O método
Jobs. Use o método da APIJobspara ver métricas sobre a utilização de espaços para uma tarefa.Cloud Monitoring. Pode usar o Cloud Monitoring para criar painéis de controlo para monitorizar os seus slots atribuídos. Com um painel de controlo do Cloud Monitoring, pode ver a utilização de slots para cada reserva e para cada tipo de tarefa, em todos os projetos na reserva. Para mais informações acerca das métricas disponíveis para o painel de controlo do Cloud Monitoring, consulte o artigo Métricas disponíveis para visualização.
Veja a sua fatura baseada na capacidade
Para ver a sua fatura baseada na capacidade em tempo real, siga estes passos:
Na Google Cloud consola, aceda à página Faturação.
Selecione o projeto da conta de faturação para o qual quer ver a fatura.
Navegue para a secção Relatórios e, de seguida, na secção Filtros, faça o seguinte:
- Na lista Serviços, selecione BigQuery e selecione tudo o que for aplicável.
- Selecione Todos os SKUs na lista SKUs.
Atribuição do custo da reserva
Esta funcionalidade permite-lhe atribuir taxas de reserva à utilização de consultas específicas em todos os projetos que usaram a reserva. Isto resulta em custos líquidos mais precisos para cada base de projeto.
Todos os clientes da API BigQuery Reservations têm um item de linha"Atribuição de slots de análise" nos respetivos dados de faturação da Cloud. Este item de linha está incluído na página Faturação e na exportação do Cloud Billing.
Este elemento publicitário mostra as horas de espaço usadas por projeto. Não incorre em custos e não afeta os totais das suas faturas.
Registos de auditoria
A criação, a eliminação e a atualização de recursos relacionados com as reservas do BigQuery são registadas nos registos de auditoria do proprietário do projeto. Para mais informações, consulte o Registo de auditoria.
Monitorize o dimensionamento automático com o esquema de informações
Pode usar os seguintes scripts SQL para verificar os segundos de espaço faturados para uma edição específica. Tem de executar estes scripts no mesmo projeto em que as reservas foram criadas. O primeiro script mostra os segundos de espaço faturados cobertos por commitment_plan, enquanto o segundo script mostra os segundos de espaço faturados que não estão cobertos por um compromisso.
Só tem de definir o valor de três variáveis para executar estes scripts:
start_timeend_timeedition_to_check
Estes scripts estão sujeitos às seguintes ressalvas:
As reservas e os compromissos de capacidade eliminados são removidos das vistas do esquema de informações no final do período de retenção de dados. Especifique um período recente que não contenha reservas nem compromissos eliminados para obter resultados corretos.
O resultado dos scripts pode não corresponder exatamente à fatura devido a pequenos erros de arredondamento.
O script seguinte agrega as vagas de ajuste de escala automático por edição.
