基于文件的服务发现

现有配置：

[root@mcw03 ~]# cat /etc/prometheus.yml 
# 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:
  - "rules/node_rules.yml"
  # - "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'.

    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'agent1'   
    static_configs:
    - targets: ['10.0.0.14:9100','10.0.0.12:9100']
  - job_name: 'promserver'   
    static_configs:
    - targets: ['10.0.0.13:9100']
  - job_name: 'server_mariadb' 
    static_configs:
    - targets: ['10.0.0.13:9104']
  - job_name: 'docker' 
    static_configs:
    - targets: ['10.0.0.12:8080']
    metric_relabel_configs:
    - regex: 'kernelVersion'
      action: labeldrop
[root@mcw03 ~]# 

把static_configs 替换成file_sd_configs

配置刷新重载文件配置的时间。可以不用手动刷新
