MySQL-MongoDB開源監(jiān)控利器之PMM-創(chuàng)新互聯(lián)

  最近要對數(shù)據(jù)庫的監(jiān)控體系進(jìn)行改進(jìn),發(fā)現(xiàn)Percona 公司的一款開源的監(jiān)控工具Percona Monitoring and Management(PMM) 對于MySQL的監(jiān)控指標(biāo)各項(xiàng)值比較全面準(zhǔn)確,現(xiàn)在公司內(nèi)部的開發(fā)測試環(huán)境進(jìn)行了部署體驗(yàn)。

10年積累的做網(wǎng)站、網(wǎng)站設(shè)計(jì)經(jīng)驗(yàn),可以快速應(yīng)對客戶對網(wǎng)站的新想法和需求。提供各種問題對應(yīng)的解決方案。讓選擇我們的客戶得到更好、更有力的網(wǎng)絡(luò)服務(wù)。我雖然不認(rèn)識你,你也不認(rèn)識我。但先網(wǎng)站策劃后付款的網(wǎng)站建設(shè)流程,更有麟游免費(fèi)網(wǎng)站建設(shè)讓你可以放心的選擇與我們合作。

  主要的架構(gòu)圖如下:源于官方

MySQL-MongoDB開源監(jiān)控利器之PMM

  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(shù)據(jù)的收集方式并發(fā)送到服務(wù)端的QAN API\Consul API\Prometheus等各個(gè)API然后通過Grafana來展示數(shù)據(jù)指標(biāo),界面非常靚麗

  Pmm 的server端的運(yùn)行方式主要有官方提供的以下三種方式:

   1.已經(jīng)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(xì)的請參考官方文檔

https://www.percona.com/doc/percona-monitoring-and-management/index.html

#Dokcer方式部署

提前準(zhǔn)備好系統(tǒng)和Docker服務(wù),安裝不在這里展示

1-創(chuàng)建容器的數(shù)據(jù)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(chuàng)建容器的運(yùn)行實(shí)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(jiān)控

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

OK, PMM server is alive.

#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(shí)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)
