Foreword
Database monitoring tools most commonly used is the zabbix, data collection zabbix able to show up graphically, and timely warning by setting a threshold. Zabbix can handle text to die for, say sql database crawl running, the zabbix can not do anything. If sql performed within this period of time, commonly used means to see, we can pull oracle for some time awr report analysis, there is no similar analysis mysql and mongodb, only to slow the log inside Amoy. Next introduce a monitoring tool for mysql, mongodb of (PMM).
(PMM) is an open-source open-source platform for managing and monitoring the performance of MySQL and MongoDB, collected by PMM client DB monitoring data with third-party software Grafana drawing displayed. PMM addition to monitoring indicators database system and some outside, but also to show slow log database within a specified time frame, similar to Oracle in the AWR SQL ordered by Elapsed Time.

Installation
pmm pmm-server and divided pmm-agent. pmm-server deployed on a separate machine, pmm-agent deployed on the monitored machine. Here is the official online presentation pmm architecture.
end server
Installation way using docker, I used here is the environment centos7 (recommended centos7)
