prometheus + mysqld_exporter + grafana 实现对mysql db的监控

https://blog.csdn.net/hfut_wowo/article/details/78536022

1、参考这篇博文
2、博主的用的是windows版本 prometheus-2.5.0-rc.2.windows-amd64，mysqld_exporter-0.11.0.windows-amd64

3、prometheus和mysqld_exporter下载地址   https://prometheus.io/download/#mysqld_exporter

下载后mysqld_exporter 没有.my.cnf

手动新建一个内容如下

[client]
host=127.0.0.1
user=root
password=root

4、修改prometheus.yml 文件如下

# 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: mysql
    static_configs:
    - targets: ['localhost:9104']
      labels:
          instance: mydb
    

5、其他步骤同上面博文连接所述

6、spring boot集成prometheus
