zabbix系列zabbix3.4監(jiān)控mysql5.7

本來想用python腳本監(jiān)控一下mysql的，沒有找到相關(guān)資料，懶得折騰了，使用官方自帶的監(jiān)控模板進行監(jiān)控mysql

添加zabbix-agent配置文件

把默認(rèn)的userparameter_mysql.conf 文件進行替換為一下內(nèi)容
[root@test-mq01 zabbix_agentd.d]# cat userparameter_mysql.conf

#UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/var/lib/zabbix mysql -N | awk '{print $$2}'
UserParameter=mysql.status[*],/etc/zabbix/script/mysql/chk_mysql.sh $1

#UserParameter=mysql.size[*],bash -c 'echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/var/lib/zabbix mysql -N'

#UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping | grep -c alive
UserParameter=mysql.ping,mysqladmin -u root -pRoo -P3306 -h292.168.2.252  ping | grep -c alive
UserParameter=mysql.version,mysql -V

添加chk_mysql.sh腳本文件

/etc/zabbix/script/mysql/chk_mysql.sh

在zabbix-web端主機添加模板鏈接

重啟監(jiān)控端agent

service zabbix-agent restart

zabbix server端測試是否有數(shù)據(jù)

[root@tools-jenkins ~]# zabbix_get -s 192.168.2.41 -k mysql.status[Questions]
3533479678

[Warning] Using a password on the command line interface can be insecure.

這個其實很簡單，腳本中導(dǎo)入export MYSQL_PWD=<password>，或者/etc/bashrc導(dǎo)入export MYSQL_PWD=<password>
最后腳本少-p，大概格式是這樣：

#原數(shù)據(jù)連接
# 數(shù)據(jù)連接
MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER}  -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}"
# 新數(shù)據(jù)連接
MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER}  -h${MYSQL_HOST} -P${MYSQL_PORT}"
