# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093

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

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # 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'.
    # 暴露路径
    metrics_path: /actuator/prometheus
    
    static_configs:
      # SpringBoot的ip和端口
      - targets: ["localhost:10086"]

启动prometheus

要修改Prometheus的拉取数据时间为1秒,您需要调整Prometheus的配置文件中的以下两个参数:

  1. scrape_interval:这个参数指定了Prometheus拉取目标配置的时间间隔,单位为秒。您可以将该参数设置为1秒,以实现每秒拉取一次数据。
  2. scrape_timeout:这个参数指定了Prometheus拉取目标配置的超时时间,单位为秒。您需要将该参数设置为大于1秒的值,以确保Prometheus有足够的时间完成对目标配置的拉取。

以下是一个示例Prometheus配置文件(通常命名为prometheus.yml),其中将scrape_interval设置为1秒:

global:
  scrape_interval: 1s

scrape_configs:
  - job_name: 'example_job'
    scrape_interval: 1s
    scrape_timeout: 5s
    static_configs:
      - targets: ['example.com:8080']

在上述示例中,scrape_interval被设置为1秒,而scrape_timeout被设置为5秒。请根据您的实际需求进行调整。

请注意,将拉取时间间隔设置为非常短的时间可能会导致Prometheus对目标配置产生大量的请求,从而可能对目标应用程序造成负面影响。因此,在实际应用中,请根据目标应用程序的性能和可接受的网络负载进行适当的调整。

  • 根据自己的场景选择合适的监控图标,能更好的展示我们监控的指标

后台SpringBoot服务添加自定义监控数据,上送给prometheus
