zabbix部署文檔

zabbix部署完之后

zabbix-agent操作

1.監控mysql，首先要先安裝mysql

[root@localhost ~]# yum -y install mariadb mariadb-server

2.編寫mysql監控項的腳本

在zabbix-agent先授權個用戶 不然測試時沒有權限

[root@localhost ~]# mysqlWelcome to the MariaDB monitor. Commands end with ; or \g.Your MariaDB connection id is 33Server version: 5.5.65-MariaDB MariaDB ServerCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type "help;" or "\h" for help. Type "\c" to clear the current input statement.MariaDB [(none)]> grant all on *.* to "check"@"localhost" identified by "123";Query OK, 0 rows affected (0.00 sec)

mysql監控的內容主要有

• 主從的狀態 (得先配置主從 在下面)
• 流量檢測 發送，接受常規操作 增刪改查
• 某個庫、某個表的大小
• tps(每秒查詢處理的事務數）qps(每秒能處理多少次請求數)

[root@localhost ~]# mkdir /etc/zabbix/scipts[root@localhost ~]# cd /etc/zabbix/scipts/[root@localhost scipts]# vim mysql.sh #!/bin/bashmysql="mysql -ucheck -p123"case $1 in  # mysql主從狀態 slave_status)  $mysql -e "show slave status\G" |grep "Yes" |wc -l ;;  # mysql流量 接受 Bytes_received)  mysqladmin extended-status |grep "Bytes_received" |awk "{print $4}" ;; # mysql流量 發送 Bytes_sent)  mysqladmin extended-status |grep "Bytes_sent" |awk "{print $4}" ;; # mysql常規操作 增 Com_insert)  mysqladmin extended-status |grep -w "Com_insert" |awk "{print $4}" ;; # mysql常規操作 刪 Com_delete)  mysqladmin extended-status |grep -w "Com_delete" |awk "{print $4}" ;; # mysql常規操作 改 Com_update)  mysqladmin extended-status |grep -w "Com_update" |awk "{print $4}"		;; # mysql常規操作 查 Com_select)  mysqladmin extended-status |grep -w "Com_select" |awk "{print $4}" ;; # mysql tps tps)  mysqladmin status |awk "{print $6/$2}" ;; # mysql qps=(rollback+commit)/uptime qps)  rollback=$(mysqladmin extended-status |grep -w "Com_rollback" |awk "{print $4}")  commit=$(mysqladmin extended-status |grep -w "Com_commit" |awk "{print $4}")  uptime=$(mysqladmin status |awk "{print $2}")  count=$[$rollback+$commit]  echo "$count $uptime" > /tmp/a.txt  cat /tmp/a.txt |awk "{print $1/$2}" ;; # 庫大小 我們這里拿mysql庫舉例 db)  $mysql -e "select sum(data_length) from information_schema.tables where table_schema="mysql"" |sed -n "2p" ;; # 表大小 我們這里拿mysql下面的user表舉例 tb)  $mysql -e "select sum(data_length) from information_schema.tables where table_schema="mysql" and table_name="user"" |sed -n "2p" ;;esac

3.自定義鍵值key 重啟zabbix-agent

[root@localhost scipts]# cd /etc/zabbix/zabbix_agentd.d/[root@localhost zabbix_agentd.d]# vim mysql.confUserParameter=mysql[*],/etc/zabbix/scipts/mysql.sh $1[root@localhost zabbix_agentd.d]# systemctl restart zabbix-agent

4.在zabbix-server測試 先安裝zabbix-get

[root@localhost ~]# yum -y install zabbix-get[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[slave_status]2[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[Bytes_received]850970[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[Bytes_sent]224906[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[Com_insert]3001[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[Com_delete]135[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[Com_update]128[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[Com_select]19[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[qps]0.864842[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[tps]1.92936[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[db]555118[root@localhost ~]# zabbix_get -s 192.168.27.137 -k mysql[tb]420

報錯處理

zabbix頁面上添加監控項和圖形

查看mysql流量數據

查看mysql qps tps

查看mysql主從狀態

查看mysql常規操作

查看mysql庫表大小
