--web.telemetry-path  default:/metrics
--web.route-prefix default:""
--persistence.file default: ""
--persistence.interval default: 5m

在Prometheus中配置pushgateway及pull pushgateway数据配置

# prometheus配置文件中配置pull pushgateway组件配置
- job_name: 'pushgateway'
  scrape_interval: 60s
  metrics_path: /metrics
  static_configs:
  - targets: ["push-prometheus.xxx.xx.xx]
# prometheus的deployment配置文件配置环境变量，这样prometheus才会去pull pushgateway缓存的数据
# 所有推到pushgateway的数据都会在/metrics接口的体现
