一分钟部署prometheus&grafana全方面监控SpringBoot项目

0x01 创建目录

找一个你喜欢的地方，创建项目根目录

example:

[root@demo-78 ~]#  mkdir /data/prometheus 

0x02 创建配置文件

进入到项目根目录：

[root@demo-78 ~]#  cd /data/prometheus 

需要新建三个文件，分别是docker-compose.yml、prometheus.yml、node_down.yml，详细配置如下

在以下配置中，除了docker-compose.yml中的端口映射配置以外，所有你能看到的关于host、port、username、passowrd的配置，都修改成你自己的，顺便注意一下docker-compose.yml配置中关于文件挂载的路劲问题。

prometheus.yml配置如下：

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: ['10.0.5.78:9093']       # - alertmanager:9093  # Load rules once and periodically evaluate them according to the global 'evaluation_interval'. rule_files:   - "node_down.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: ['10.0.5.78:9094']    - job_name: 'redis'     static_configs:      - targets: ['10.0.5.78:9121']        labels:          instance: redis    - job_name: 'node'     scrape_interval: 8s     static_configs:      - targets: ['10.0.5.78:9100']        labels:          instance: node    - job_name: 'cadvisor'     static_configs:      - targets: ['10.0.5.78:8088']        labels:          instance: cadvisori             #基于文件自动加载新监控任务   - job_name: 'file_ds'     file_sd_configs:     - files: ['/etc/prometheus/reload/*.yml']       refresh_interval: 5s 

docker-compose.yml配置如下：

node_down.yml配置如下：

groups: - name: node_down   rules:   - alert: InstanceDown     expr: up == 0     for: 1m     labels:       user: test     annotations:       summary: "Instance {{ $labels.instance }} down"       description: "{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 1 minutes."

0x04 FAQ

1. 如何使用prometheus.yml配置的 "基于文件自动加载新监控任务"

   项目启动后，在根目录会生产一个名叫reload的文件夹，只需要在当前文件夹中加入新增的监控配置就能自动注册到prometheus服务中,配置书写格式如下：

   [root@demo-78 ~]# cat /prometheus/reload/web.yml  - targets:   - '10.0.5.79:9100'   labels:     job: 'pig-web'     __metrics_path__: '/web/actuator/prometheus' 

   或：

   [root@demo-piggpt-78 ~]# cat /prometheus/reload/mysql.yml  - targets: ['10.0.5.78:9104'] 

   这里只是给个实例，有特别的需求请自行查看资料，这两种写法唯一的区别在于：第一种写法我需要自定义metrics_path，否则默认拉取指标的路径（第二种写法）就是：10.0.5.78:9104/metrics，对于很多官网的exporter，使用第二种方式即可

2. 容器mysql-export启动报错：caller=mysqld_exporter.go:225 level=info msg="Error parsing host config" file=.my.cnf err="no configuration found"

   由于mysql-exporter更新过后，配置写法有改变，截止2024年5月28日，最新的mysql-exporter:0.15.1按照当前配置部署能够成功启动，如遇无法启动，请自行查看官方文档
