一、PMM简介

之前发布过一篇Prometheus+Grafana的文章，连接为：【DB宝36】使用Docker分分钟搭建漂亮的prometheus+grafana监控，今天我们来介绍一下另一个监控工具：PMM。

PMM（Percona Monitoring and Management）是一个免费的开源平台，用于管理和监视数据库性能，在docker环境中即可运行。它可以主动管理和监控MySQL（AWS RDS MySQL、Aurora MySQL、用户自建MySQL实例）、MariaDB、MongoDB、PostgreSQL等数据库，也可以监控ProxySQL中间件，并提供了众多指标与多样告警方式。

Percona Monitoring and Management (PMM)是一款开源的用于管理和监控MySQL和MongoDB性能的开源平台，通过PMM客户端收集到的DB监控数据用第三方软件Grafana画图展示出来。

PMM提供了对MyISAM、InnoDB、TokuDB和PXC/Glarera的监控，另外也提供了Query Analytics的功能，可以检视执行了哪些SQL指令，并对执行效能较差的语法进行优化。另外在新版本还支持了MySQL复制拓扑图结构构造。Demo官网：http://pmmdemo.percona.com

PMM针对操作系统的部份也提供了硬盘、网络、CPU和RAM的监控，特别的是它提供了Context switches、Processes和interrupts的监控，Context Switches可以看到CPU上下切换文的状况，Processes可以方便了解系统有多少程序在等待I/O。

PMM整体来说算是一款不错的监控产品，针对MySQL、PG、Mongo都有很专业的指标统计，而且部署简单整套打包到容器中。2.0之后底层持久化数据库从MySQL更换为PG后，性能更是有很大提升。

PMM的体系结构如下所示：

二、安装使用

https://www.percona.com/software/pmm/quickstart

https://www.percona.com/doc/percona-monitoring-and-management/2.x/

https://hub.docker.com/r/percona/pmm-server/tags
docker pull percona/pmm-server:latest


-- 拉取镜像
docker pull percona/pmm-server:2.14


-- 创建PMM数据容器
docker rm lhr-pmm-data
docker create --name lhr-pmm-data \
   -v /pmmdata \
   percona/pmm-server:2.14 /bin/true

-- 创建PMM服务器容器
docker rm -f lhr-pmm-server
docker run -d --name lhr-pmm-server -h lhr-pmm-server \
  -p 280:80 -p 2443:443 \
  --volumes-from lhr-pmm-data \
  -e SERVER_USER=lhr \
  -e SERVER_PASSWORD=lhr \
  -e ORCHESTRATOR_ENABLED=true \
  -e METRICS_RETENTION=48h \
  --restart always \
  percona/pmm-server:2.14


-- 访问web界面

admin/admin

-- 进入PMM服务器
docker exec -it lhr-pmm-server bash

-- 连接到PMM服务器
pmm-admin config --server-insecure-tls --server-url=https://admin:admin@127.0.0.1:443
pmm-admin list

可以使用http或https访问，端口号不一样。

登陆之后就可以看到以下信息：

[root@lhr-pmm-server opt]# pmm-admin config --server-insecure-tls --server-url=https://admin:admin@127.0.0.1:443

三、监控MySQL数据库

可以添加多个被监控实例，执行过程：

[root@lhr-pmm-server opt]# pmm-admin add mysql --query-source=perfschema --username=root --password=lhr  --host=192.168.66.35 --port=3317 --service-name=mysql-192.168.66.35-3317

四、监控PG数据库

PMM服务器的后端元数据存储用的是PG数据库，所以，我们可以直接监控该库：

[root@lhr-pmm-server opt]# pmm-admin add postgresql --username=pmm-managed --password=pmm-managed --host=127.0.0.1 --port=5432 --service-name=PG-127.0.0.1-5432
PostgreSQL Service added.

五、监控MongoDB数据库

使用PMM监视集群时，应使用pmm-admin add命令启用对每个实例的监视，这包括分片集群中的副本集、mongos和所有配置服务器。

-- 无密码
pmm-admin add mongodb --host=192.168.66.35 --port=27017 --service-name=mongodb-192.168.66.35-27017

-- 有密码
pmm-admin add mongodb --username=root --password=lhr mongodb-192.168.66.35-37017 192.168.66.35:37017
pmm-admin add mongodb --username=root --password=lhr --host=192.168.66.35 --port=37017 --service-name=mongodb-192.168.66.35-37017


-- 集群、复制集
pmm-admin add mongodb --cluster lhr-mongo-cluster --replication-set=lhr_rep --username=root --password=lhr  --host=192.168.66.35 --port=37020 --service-name=mongodb-192.168.66.35-37020-lhr_rep
pmm-admin add mongodb --cluster lhr-mongo-cluster --replication-set=lhr_rep --username=root --password=lhr  --host=192.168.66.35 --port=37021 --service-name=mongodb-192.168.66.35-37021-lhr_rep
pmm-admin add mongodb --cluster lhr-mongo-cluster --replication-set=lhr_rep --username=root --password=lhr  --host=192.168.66.35 --port=37022 --service-name=mongodb-192.168.66.35-37022-lhr_rep
pmm-admin add mongodb --cluster lhr-mongo-cluster --replication-set=lhr_rep --username=root --password=lhr  --host=192.168.66.35 --port=37023 --service-name=mongodb-192.168.66.35-37023-lhr_rep
pmm-admin add mongodb --cluster lhr-mongo-cluster --replication-set=lhr_rep --username=root --password=lhr  --host=192.168.66.35 --port=37024 --service-name=mongodb-192.168.66.35-37024-lhr_rep

-- 查询
pmm-admin list

添加完成后：

[root@lhr-pmm-server opt]# pmm-admin list

六、监控ProxySQL中间件

PMM默认没有ProxySQL的监控模板，需要我们自行下载：https://github.com/percona/grafana-dashboards/blob/master/dashboards/ProxySQL_Overview.json

下载后上传到PMM的监控界面中就可以了。
