Grafana dashboard: Dashboard Basic - Docker e Prometheus
Description: Dashboard criada com o propósito de exemplificar o uso das ferramentas Prometheus, Node-exporte e Grafana, durante o evento ERAD - UFMS 2020. Por esse motivo essa dashboard foi basead na Node Exporter for Prometheus Dashboard EN - v20200628.

# Dashboard Grafana

Dashboard criada com o propósito de exemplificar o uso das ferramentas Prometheus, Node-exporte e Grafana, durante o evento ERAD - UFMS 2020. Por esse motivo essa dashboard foi basead na [Node Exporter for Prometheus Dashboard EN ]("https://github.com/starsliao/Prometheus/tree/master/node_exporter") - v20200628.

Essa dashboard está expondo algumas métricas sobre os serviços que estão dentro dos contêineres e as maquinas que compoem o [Swarm](https://docs.docker.com/engine/swarm/)
