四 Prometheus + consul

服务发现方式:

#Prometheus数据源的配置主要分为静态配置和动态发现, 常用的为以下几类:
static_configs:              #静态服务发现
file_sd_configs:             #文件服务发现
dns_sd_configs: DNS          #服务发现
kubernetes_sd_configs:       #Kubernetes 服务发现
consul_sd_configs: Consul    #Consul 服务发现
...

#在监控kubernetes的应用场景中，频繁更新的pod，svc，等等资源配置应该是最能体现Prometheus监控目标自动发现服务的好处

Consul:

wget https://releases.hashicorp.com/consul/1.6.1/consul_1.6.1_linux_amd64.zip
unzip consul_1.5.3_linux_amd64.zip
nohup ./consul agent -dev  -bind 0.0.0.0 -client 0.0.0.0 & 
./consul agent -server -ui -bootstrap-expect 1 -data-dir /tmp/consul &
