#scrape_timeout is set to the global default (10s).
#Alertmanager configuration
alerting:alertmanagers:- static_configs:- targets:
#- alertmanager:9093

#The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.- job_name: 'prometheus'
#metrics_path defaults to '/metrics'
#scheme defaults to 'http'.static_configs:- targets: ['localhost:9090']- job_name: "node"static_configs:- targets: ["localhost:9100"]在文件夹内启动：
sudo ./prometheus启动后在浏览器中访问：http://IP:9090即可
