# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
 # - "first_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.

###以下内容为SpringBoot应用配置
 - job_name: 'springboot_prometheus'
 scrape_interval: 5s
 metrics_path: '/actuator/prometheus'
 static_configs:
  - targets: ['127.0.0.1:8080']
