普罗米修斯MySQL监控

1.下载MySQL的exporter

下载地址：https://prometheus.io/download/

 2.上传到需要监控的MySQL的机器上进行解压

 解压安装

 tar -xzvf mysqld_exporter-0.14.0.linux-amd64.tar.gz 

 为了后续使用方便将名称修改为：mysqld_exporter

 export DATA_SOURCE_NAME='root:123456@@(127.0.0.1:3306)'

查看9104端口（mysqld_exporter默认）

 修改普罗米修斯web的配置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.
  # 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'.

    static_configs:
      - targets: ["localhost:9090"]
  - job_name: "mysql114"
    static_configs:
      - targets: ["10.0.0.13:9104"]

修改后重新启动

 查看web界面：

 这是为什么呢？是因为13的服务器开着防火墙呢。

 关闭防火墙后再看状态

 再次查看web界面就正常了。
