prometheus

特点：

• 有多维度的数据模型
• 有自己的查询语言：PromQL
• 不依赖分布式存储
• 支持通过中间网关推送时间序列数据
• 通过服务发现或静态配置，来发现目标服务对象
• 支持图标和界面展示

部署Prometheus

[root@localhost ~]# docker pull prom/Prometheus   //下载普罗米修斯
[root@localhost ~]# vim /tmp/prometheus.yml      //创建静态普罗米修斯yml文件
#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.                  
   # scrap_timeout is set to the global default (10s).

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

#Load rules once andpreiodically 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 scrapedfrom this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
 
    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'docker'      ##定义一个叫docker的组
    static_configs:
- targets: ['192.168.200.14:8080']

[root@localhost ~]# docker run -d --name=prometheus -p 9090:9090 -v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml -v /etc/localtime:/etc/localtime prom/prometheus

页面访问端口9090
