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 &
http://ip:8500/ui
Prometheus 安装略过
