Prometheus监控指南¶

OpsAny支持集成Prometheus监控，社区版可以手工安装Exporter，进行监控。

集成Prometheus¶

OpsAny通过Prometheus实现主机、组件、应用的监控，支持自定义指标采集插件，管理功能位于【管控平台】-【采集插件】-【指标采集】。

集成位置：【管控平台】-【采控管理】-【Prometheus集成】添加Prometheus Server。

Prometheus监控MySQL¶

1.部署MySQL Exporter¶

[root@dev ~]# cd /usr/local/src
[root@dev src]# wget https://github.com/prometheus/mysqld_exporter/releases/download/v0.13.0/mysqld_exporter-0.13.0.linux-amd64.tar.gz
[root@dev src]# tar zxf mysqld_exporter-0.13.0.linux-amd64.tar.gz
[root@dev src]# mv mysqld_exporter-0.13.0.linux-amd64 /usr/local/
[root@dev src]# ln -s /usr/local/mysqld_exporter-0.13.0.linux-amd64/ /usr/local/mysqld_exporter

2.配置系统服务¶

[root@dev src]# vim /usr/lib/systemd/system/mysql_exporter.service
[Unit]
Description=https://prometheus.io

[Service]
Restart=on-failure
ExecStart=/usr/local/mysqld_exporter/mysqld_exporter --config.my-cnf=/usr/local/mysqld_exporter/.my.cnf

[Install]
WantedBy=multi-user.target

3.配置MySQL¶

登录到受监控的MySQL中

[root@dev ~]# mysql -u root -p

创建MySQL监控账户并授权

MariaDB [(none)]> CREATE USER 'opsany_monitor'@'localhost' IDENTIFIED BY 'OpsAny@2020';
MariaDB [(none)]> GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'opsany_monitor'@'localhost';

配置MySQL监控账户

[root@dev ~]# vim /usr/local/mysqld_exporter/.my.cnf
[client]
user=opsany_monitor
password=OpsAny@2020

4.启动监控插件¶

systemctl daemon-reload
systemctl restart mysql_exporter.service

5.测试运行¶

curl http://127.0.0.1:9104/metrics

测试没有问题，可以修改Prometheus配置去添加target。
