一、PMM簡介
之前發布過一篇Prometheus+Grafana的文章，連接為：【DB寶36】使用Docker分分鍾搭建漂亮的prometheus+grafana監控，今天我們來介紹一下另一個監控工具：PMM。
PMM（Percona Monitoring and Management）是一個免費的開源平台，用於管理和監視數據庫性能，在docker環境中即可運行。它可以主動管理和監控MySQL（AWS RDS MySQL、Aurora MySQL、用戶自建MySQL實例）、MariaDB、MongoDB、PostgreSQL等數據庫，也可以監控ProxySQL中間件，並提供了眾多指標與多樣告警方式。
Percona Monitoring and Management (PMM)是一款開源的用於管理和監控MySQL和MongoDB性能的開源平台，通過PMM客戶端收集到的DB監控數據用第三方軟件Grafana畫圖展示出來。
PMM提供了對MyISAM、InnoDB、TokuDB和PXC/Glarera的監控，另外也提供了Query Analytics的功能，可以檢視執行了哪些SQL指令，並對執行效能較差的語法進行優化。另外在新版本還支持了MySQL復制拓撲圖結構構造。Demo官網：http://pmmdemo.percona.com
PMM針對操作系統的部份也提供了硬盤、網絡、CPU和RAM的監控，特別的是它提供了Context switches、Processes和interrupts的監控，Context Switches可以看到CPU上下切換文的狀況，Processes可以方便了解系統有多少程序在等待I/O。
PMM整體來說算是一款不錯的監控產品，針對MySQL、PG、Mongo都有很專業的指標統計，而且部署簡單整套打包到容器中。2.0之后底層持久化數據庫從MySQL更換為PG后，性能更是有很大提升。
PMM的體系結構如下所示：

三、監控MySQL數據庫
可以添加多個被監控實例，執行過程：

四、監控PG數據庫
PMM服務器的后端元數據存儲用的是PG數據庫，所以，我們可以直接監控該庫：
[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

五、監控MongoDB數據庫
使用PMM監視集群時，應使用pmm-admin add命令啟用對每個實例的監視，這包括分片集群中的副本集、mongos和所有配置服務器。
-- 無密碼
pmm-admin add mongodb --host=192.168.66.35 --port=27017 --service-name=mongodb-192.168.66.35-27017
