? ? 最近要對數據庫的監控體系進行改進，發現Percona 公司的一款開源的監控工具Percona Monitoring and Management(PMM) 對于MySQL的監控指標各項值比較全面準確，現在公司內部的開發測試環境進行了部署體驗。

? ? 主要的架構圖如下：源于官方

? ? 可以看到主要是由客戶端的代理程序node_export\mysqld_export\mongodb_export等和客戶端管理工具pmm-admin做為數據的收集方式并發送到服務端的QAN API\Consul API\Prometheus等各個API然后通過Grafana來展示數據指標，界面非常靚麗

? ? Pmm 的server端的運行方式主要有官方提供的以下三種方式：

? ? ? 1.已經集成好的Docker方式

? ? ? 2.集成好的VirtualBox方式

? ? ? 3. Amazon Machine Image (AMI)

? ? ?在這里我用的是Docker方式，輕量部署、升級很方便

? ? PMM的client安裝比較方便，直接安裝官方的yum安裝就OK了

#詳細的請參考官方文檔

#Dokcer方式部署

提前準備好系統和Docker服務，安裝不在這里展示

1-創建容器的數據磁盤

docker?create?\-v?/opt/prometheus/data?\-v?/opt/consul-data?\-v?/var/lib/mysql?\-v?/var/lib/grafana?\--name?pmm-data?\percona/pmm-server:1.1.1?/bin/true

2-創建容器的運行實例

docker?run?-d?\-p?80:80?\--volumes-from?pmm-data?\--name?pmm-server?\--restart?always?\percona/pmm-server:1.1.1

#客戶端安裝

[root@master ~]# yum install http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm

[root@master ~]# yum install -y pmm-client

#增加客戶端mysql監控

[root@master ~]# pmm-admin config ?--server 192.168.100.171

OK, PMM server is alive.

PMM Server ? ? ?| 192.168.100.171?

Client Name ? ? | master.wboy.com

Client Address ?| 192.168.100.41?

[root@master ~]# pmm-admin list

pmm-admin 1.1.1

PMM Server ? ? ?| 192.168.100.171?

Client Name ? ? | master.wboy.com

Client Address ?| 192.168.100.41?

Service Manager | unix-systemv

No monitoring registered for this node identified as 'master.wboy.com'.

#命令幫助

[root@master ~]# pmm-admin ?add --help

This command is used to add a monitoring service.

Usage:

? pmm-admin add [command]

Available Commands:

? mysql ? ? ? ? ? ?Add complete monitoring for MySQL instance (linux and mysql metrics, queries).

? linux:metrics ? ?Add this system to metrics monitoring.

? mysql:metrics ? ?Add MySQL instance to metrics monitoring.

? mysql:queries ? ?Add MySQL instance to Query Analytics.

? mongodb ? ? ? ? ?Add complete monitoring for MongoDB instance (linux and mongodb metrics).

? mongodb:metrics ?Add MongoDB instance to metrics monitoring.

? proxysql:metrics Add ProxySQL instance to metrics monitoring.

Flags:

? ? ? --service-port uint16 ? service port

Global Flags:

? -c, --config-file string ? PMM config file (default "/usr/local/percona/pmm-client/pmm.yml")

Use "pmm-admin add [command] --help" for more information about a command.

[root@master ~]# pmm-admin ?add ?mysql --help

This command adds the given MySQL instance to system, metrics and queries monitoring.

When adding a MySQL instance, this tool tries to auto-detect the DSN and credentials.

If you want to create a new user to be used for metrics collecting, provide --create-user option. pmm-admin will create

a new user 'pmm@' automatically using the given (auto-detected) MySQL credentials for granting purpose.

Table statistics is automatically disabled when there are more than 10000 tables on MySQL.

[name] is an optional argument, by default it is set to the client name of this PMM client.

Usage:

? pmm-admin add mysql [name] [flags]

Examples:

? pmm-admin add mysql --password abc123

? pmm-admin add mysql --password abc123 --create-user

? pmm-admin add mysql --password abc123 --port 3307 instance3307

Flags:

? ? ? --create-user ? ? ? ? ? ? ? ? ? ? ? create a new MySQL user

? ? ? --create-user-maxconn uint16 ? ? ? ?max user connections for a new user (default 10)

? ? ? --create-user-password string ? ? ? optional password for a new MySQL user

? ? ? --defaults-file string ? ? ? ? ? ? ?path to my.cnf

? ? ? --disable-binlogstats ? ? ? ? ? ? ? disable binlog statistics

? ? ? --disable-processlist ? ? ? ? ? ? ? disable process state metrics

? ? ? --disable-tablestats ? ? ? ? ? ? ? ?disable table statistics

? ? ? --disable-tablestats-limit uint16 ? number of tables after which table stats are disabled automatically (default 1000)

? ? ? --disable-userstats ? ? ? ? ? ? ? ? disable user statistics

? ? ? --force ? ? ? ? ? ? ? ? ? ? ? ? ? ? force to create/update MySQL user

? ? ? --host string ? ? ? ? ? ? ? ? ? ? ? MySQL host

? ? ? --password string ? ? ? ? ? ? ? ? ? MySQL password

? ? ? --port string ? ? ? ? ? ? ? ? ? ? ? MySQL port

? ? ? --query-source string ? ? ? ? ? ? ? source of SQL queries: auto, slowlog, perfschema (default "auto")

? ? ? --socket string ? ? ? ? ? ? ? ? ? ? MySQL socket

? ? ? --user string ? ? ? ? ? ? ? ? ? ? ? MySQL username

Global Flags:

? -c, --config-file string ? ?PMM config file (default "/usr/local/percona/pmm-client/pmm.yml")

? ? ? --service-port uint16 ? service port

#增加本地mysql實例

[root@master ~]# pmm-admin ?add ?mysql ?--user root --password root

[linux:metrics] OK, now monitoring this system.

[mysql:metrics] OK, now monitoring MySQL metrics using DSN root:***@unix(/var/lib/mysql/mysql.sock)

[mysql:queries] OK, now monitoring MySQL queries from slowlog using DSN root:***@unix(/var/lib/mysql/mysql.sock)
