promethues集成nomad

       在上一篇文章《prometheus获取Consul上注册的服务》里，已说明了如何将promethues集成consul，而nomad也可以集成到promethues中去，不废话，直接上配置文件prometheus.yml内容：

# 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:
       - 10.110.200.68:9093

# 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'.

    static_configs:
      - targets: ['localhost:9090']
  - job_name: 'nomad-client'
    metrics_path: /v1/metrics
    params: 
      format: 
        - prometheus
    consul_sd_configs:
      - server: '10.110.200.184:8500'
        services: 
          - nomad-client
  - job_name: consul
    consul_sd_configs:
      - server: '10.110.200.40:8500'
    relabel_configs:
      - source_labels: [__meta_consul_tags]
        regex: .*,prometheus,.*
        action: keep
      - source_labels: [__meta_consul_service]
        target_label: job
      - source_labels: [__meta_consul_tags]  
        regex: .*,smartms,.*
        target_label:  __metrics_path__  
        replacement:   '/actuator/prometheus'
      - source_labels: [__meta_consul_tags]  
        regex: .*,type=([^,]+),.*
        target_label:  type  
        replacement:   ${1}
      - source_labels: [__meta_consul_tags]  
        regex: .*,env=([^,]+),.*
        target_label:  env  
        replacement:   ${1}
      - source_labels: [__meta_consul_tags]  
        regex: .*,app_id=([^,]+),.*
        target_label:  app_id  
        replacement:   ${1}
           

可以在targets界面看到nomad-client的情况

在metrics就能选到nomad的相关指标了
