Consultas Usadas na Solução Kubernetes

As consultas são usadas para extrair as métricas, os eventos, a topologia e os dados de análise a serem exibidos em vários painéis disponíveis na solução Kubernetes. Algumas das consultas baseadas em log, como as do Sistema Kube, integridade do SO, Eventos, Resumo de Cargas de Trabalho, Resumo do Nó e Resumo do Pod, devem ser executadas no Log Explorer e as outras consultas são baseadas em métricas que devem ser executadas no Metric Explorer.
