zabbix部署文檔
zabbix部署完之后
zabbix-agent操作
1.監(jiān)控mysql,首先要先安裝mysql
[root@localhost ~]# yum -y install mariadb mariadb-server
2.編寫mysql監(jiān)控項(xiàng)的腳本
在zabbix-agent先授權(quán)個(gè)用戶 不然測試時(shí)沒有權(quán)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(jiān)控的內(nèi)容主要有
- 主從的狀態(tài) (得先配置主從 在下面)
- 流量檢測 發(fā)送,接受常規(guī)操作 增刪改查
- 某個(gè)庫、某個(gè)表的大小
- tps(每秒查詢處理的事務(wù)數(shù))qps(每秒能處理多少次請求數(shù))
[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(tài) 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(fā)送 Bytes_sent) mysqladmin extended-status |grep "Bytes_sent" |awk "{print $4}" ;; # mysql常規(guī)操作 增 Com_insert) mysqladmin extended-status |grep -w "Com_insert" |awk "{print $4}" ;; # mysql常規(guī)操作 刪 Com_delete) mysqladmin extended-status |grep -w "Com_delete" |awk "{print $4}" ;; # mysql常規(guī)操作 改 Com_update) mysqladmin extended-status |grep -w "Com_update" |awk "{print $4}" ;; # mysql常規(guī)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

zabbix頁面上添加監(jiān)控項(xiàng)和圖形
查看mysql流量數(shù)據(jù)
查看mysql qps tps
查看mysql主從狀態(tài)
查看mysql常規(guī)操作
查看mysql庫表大小
