使用Prometheus:

  配置 prometheus.yml:

global:  scrape_interval:     15s # By default, scrape targets every 15 seconds.  # Attach these labels to any time series or alerts when communicating with  # external systems (federation, remote storage, Alertmanager).  external_labels:    monitor: 'codelab-monitor'# 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=
     
      ` to any timeseries scraped from this config.  - job_name: 'prometheus'    # Override the global default and scrape targets from this job every 5 seconds.    scrape_interval: 5s    static_configs:      - targets: ['localhost:9090']
