使用supervisor守护Prometheus进程

使用supervisor守护Prometheus进程

目录

• 使用supervisor守护Prometheus进程
  • 安装supervisor
  • 安装Prometheus监控系统
  • 配置supervisor

之前是将Prometheus组件注册为系统服务，要编辑好几个文件，没有shell脚本的时候手动配置比较麻烦，改用supervisor会方便不少。

只要supervisor启动，就会自动拉起Prometheus组件并守护进程。

安装supervisor

yum install -y supervisor
systemctl start supervisord && systemctl enable supervisord

安装Prometheus监控系统

• 节点：192.168.0.10
• 组件：
  • prometheus server
  • node_exporter
  • alertmanager
  • 钉钉告警插件

具体步骤可以参考其它文章，本文不做展开。

配置supervisor

1. vim /etc/supervisord.d/prometheus.ini，内容如下：（注意修改路径、IP、端口、钉钉机器人的webhook）

[program:prometheus]
command=/usr/local/prometheus/prometheus/prometheus --storage.tsdb.path=/home/data/prometheus/prometheus/ --config.file=/usr/local/prometheus/prometheus/prometheus.yml --web.listen-address=:19090 --storage.tsdb.retention=15d
directory=/usr/local/prometheus/prometheus
autostart=true
startsecs=10
startretries=3
autorestart=true


[program:alertmanager]
command=/usr/local/prometheus/alertmanager/alertmanager --storage.path="/home/data/prometheus/alertmanager/" --web.listen-address=":18081" --config.file=/usr/local/prometheus/alertmanager/alertmanager.yml --data.retention=120h --web.external-url=http://192.168.0.10:18081
directory=/usr/local/prometheus/alertmanager
autostart=true
startsecs=10
startretries=3
autorestart=true


[program:dingtalk]
command=/usr/local/prometheus/dingtalk/prometheus-webhook-dingtalk --ding.profile="webhook1=https://oapi.dingtalk.com/robot/send?access_token=xxxx"
directory=/usr/local/prometheus/dingtalk
autostart=true
startsecs=10
startretries=3
autorestart=true


[program:nodeexporter]
command=/usr/local/prometheus/node_exporter/node_exporter --web.listen-address 0.0.0.0:18080
directory=/usr/local/prometheus/node_exporter
autostart=true
startsecs=10
startretries=3
autorestart=true

2. 配置生效：supervisorctl update
3. 查看状态：
   1. supervisorctl status
   2. ps -ef | grep prometheus
